-?

b <command> -?

For certain commands, displays online help, including complete syntax, description, and other related information. For example, to see online help for the bigpipe service command, type:

b service -?

class

b class <class name> { <ip member> <ip member> ... } <ip member> ::= HOST <ip addr> | NETWORK <ip addr> MASK <ip addr>
b class <class name> { <string> <string> ... }
b class <class name> { <num> <num> ... }
b <class name> show
b class ip show
b class string show
b class value show
b class show
b class <class name> delete

Creates, shows, and deletes any classes, such as class AOL. Default classes are also shown.

The BIG-IP includes a number of predefined lists. They are:

  • AOL Network
  • Image Extensions
  • Non-routable addresses

These lists are located in the file /etc/default_classes.txt. When the bigpipe load command is issued, the lists are loaded. Unless modified by a user, these lists are not saved to the file bigip.conf.

The following are examples of class types defined with the class command. Note that string classes require escape characters in the syntax to keep from being interpreted literally by the UNIX system.

b class string_class { \".string\" ... } | '{ ".string" }'
b class numeric_class { <num> <num> ... }
b class host_class { host <ip_addr> }
b class network_class { network <ip_addr> mask <mask_addr> }

config

b config sync
b config sync all
b config sync running
b config save <file>
b config install <file>

Synchronizes configurations of two BIG-IP units in a redundant system by collecting and copying the configuration file(s) from the active unit to the standby unit (config sync). Also archives configuration files for backup purposes (config save) and installs saved files (config install).

Synchronizing configuration files

config sync without the all option synchronizes only the basic configuration file /config/bigip.conf.

config sync all synchronizes the following configuration files:

  • The common BIG/db keys
  • All common files in /config
  • All common files in /etc

config sync running synchronizes the running version of /config/bigip.conf, which is the image that resides in memory as the system runs. This file is loaded into memory on the standby unit, it is not saved.

Note: The config sync command applies only to BIG-IP and not to 3-DNS.

Saving configuration files to an archive

config save <file> saves all configuration files to a single archive file, <file>.ucs, on the local unit without copying it to the standby unit. By default, <file>.ucs is saved to the directory /user/local/ucs. An alternate location can be specified by expressing <file> as a relative or absolute path. For example:

b config save /user/local/config_backup/my_conf

This writes the file my_conf.ucs to the directory /user/local/config_backup.

Installing an archived configuration file

config install <file> reinstalls the archived configuration files saved as <file>.ucs to their working locations on the local unit.

If you use command line utilities to set configuration options, be sure to save the current configuration to the relevant files before you use the configuration synchronization feature. (Alternatively, if you want to test the memory version on the standby unit first, use bigpipe config sync running.) Use the following bigpipe command to save the current configuration:

b save

Note: A file named /usr/local/ucs/cs_backup.ucs is created prior to installing a UCS from a remote machine.

conn

b conn [ <client_ip>[:<client_service>] ] dump [mirror]

Displays information about current client connections to virtual addresses and virtual servers.

The following command displays all current client connections:

b conn dump

The output shows the source IP address, virtual server IP address, and node to which the client is connected.

Figure 7.1 Formatted output of the conn command

 bigip conn dump    

from virtual node
100.100.100.30:49152 -> 100.100.100.100:23 -> 200.200.200.10:23
100.100.101.90:49153 -> 100.100.100.100:80 -> 200.200.200.10:80
...

This command can also show connections that are active on the given BIG-IP, as well as those that are standby connections for the peer BIG-IP. By default, the dump command only shows items that are active on the given unit. To see standby items, you must use the mirror qualifier.

b conn dump mirror

default_gateway

b default_gateway use pool <pool_name>
b default_gateway show
b default_gateway delete

This command creates, shows, or deletes a pool of default gateways, with nodes in the pool corresponding to different routes. Connections originating from the system with a destination for which there is no other route choose a route from the default gateway pool. Note that the default gateway pool is not a last-hop pool for services running on the system.

There can be only one default gateway pool at any one time.

Defining a default gateway pool removes the need to define a default route. However, if a default route is defined, that route will be used when all the nodes in the default gateway pool are down.

Since the system performs route lookups on nodes as they are defined, the default gateway pool must be stored at the top of the bigip.conf file. Also, all nodes in the default gateway pool must reside on the same IP network as the system.

We recommend that all nodes in the default gateway pool have the same MTU.

As an alternative to using the default_gateway command, you can use the Setup utility, which allows you to create the default gateway pool at the time that you configure your base network.

failover

b failover active | standby | show | init | failback

This group of commands affects the fail-over status of the BIG-IP or 3-DNS system.

In an active/standby or active-active configuration, run the following command to place a BIG-IP or 3-DNS system in standby mode:

b failover standby

Show the status of the BIG-IP or 3-DNS system with the following command:

b failover show

In an active-active configuration, run the following command after you issue the bigpipe failover standby command. This allows the inactive unit to resume handling connections:

b failover failback

Note: The failback command is only applicable if you are running a redundant system in active-active mode.

You can use the bigpipe failover init command to refresh the parameters of the fail-over mechanism with any new configuration data entered in the BIG/db database.

b failover init

b global l2_aging_time <seconds>

auto_lasthop

When this variable is enabled, it automatically designates the lasthop router inside IP address as a lasthop route for replies to inbound traffic. If auto_lasthop is disabled, the lasthop router inside IP address must be specified as a lasthop pool. The default setting is enable.

fastest_max_idle_time

Sets the number of seconds a node can be left idle by the fastest load balancing mode. This forces the BIG-IP to send fewer connections to a node that is responding slowly, and also allows the BIG-IP to periodically recalculate the response time of the slow node.

fastflow_active

You can use this variable to control additional enhancements that speed packet flow for TCP connections when the packets are not fragmented. In most configurations these software enhancements are automatically turned on and do not require any additional configuration.

However, you may want to turn off these enhancements for individual virtual servers that use IPFW rate filters. With the speed enhancements on, IPFW only examines the first SYN packet in any given connection. If you want to filter all packets, you should turn the speed enhancements off. To do this, you first set the global state of the system on, and then you turn the feature off for individual virtual servers that use IPFW rate filtering. You can also change the settings for these enhancements from the command line or in the Configuration utility.

There are three global states you can set with fastflow_active. The default state is auto. The global states are:

  • off
  • auto
  • on

The additional speed enhancements are globally disabled if the sysctl variable fastflow_active is off or if fastflow_active is set to auto and an IPFW rate filter exists in the configuration.

To provide the benefits of software acceleration for virtual servers that do not use rate filtering and turn off software acceleration for virtual servers that use IPFW rate filtering, you can set the global variable fastflow_active to on with the following command:

b global fastflow_active on

After you set the sysctl variable, use the following bigpipe command to disable software acceleration for virtual servers that use IPFW rate filtering:

b virtual <ip>:<port> accelerate disable

gateway failsafe

Turns the gateway fail-safe feature on and off. This command is supported only for redundant systems.

The typical use of gateway fail-safe is a setup where active and standby BIG-IP units use different routers as gateways to the Internet. Fail-over is triggered if the gateway for the active unit is unreachable.

To arm fail-safe on the gateway, enter the following command:

b global gateway failsafe arm

To disarm fail-safe on the gateway, enter the following command:

b global gateway failsafe disarm

To see the current fail-safe status for the gateway, enter the following command:

b global gateway failsafe show

For more information about configuring gateway fail-safe, see Health monitors, on page 4-137.

ip forwarding

Enables IP forwarding for the BIG-IP. IP forwarding exposes all of the node IP addresses to the external network, making them routable on that network. The default setting is disabled.

mirror

Enables mirroring functions globally for the BIG-IP. The mirror feature duplicates the active unit's real-time connection or persistence information state on the standby unit for smooth transition to the inactive unit at fail-over. The default setting is enabled.

memory_reboot_percent

The value you type, 80 or higher, is the percentage of memory that is in use before the BIG-IP automatically reboots. The default value for this variable is 95. To disable this feature, set the value to 0.

open_3dns_ports

This variable is required only when running one or more separate 3-DNS Controllers in the network. It does not apply to running the 3-DNS software module on the BIG-IP itself. The variable is disabled on the BIG-IP when the 3-DNS Controller is not present in the network configuration. (See the 3-DNS Administrator Guide for more information.)

open_corba_ports

This variable enables and disables the CORBA ports, which allow administrative CORBA connections. The default setting is disabled.

open_snmp_ports

This variable enables and disables the SNMP ports, which allow administrative SNMP connections. The default setting is disabled.

open_telnet_port

This variable enables or disables ports for Telnet access, and the default setting is disable.

The following command sets this variable to open the Telnet port (23) to allow administrative Telnet connections. This is useful for BIG-IP units that do not support encrypted communications, or for a unit that needs to communicate with the 3-DNS software. (See the 3-DNS Administrator Guide for more information.)

The following command opens the Telnet port:

b global open_telnet_port enable

The following command closes the Telnet port:

b global open_telnet_port disable

open_ftp_ports

This variable enables or disables ports for FTP access, and the default setting is disable.

The following command open the FTP ports (20 and 21) to allow administrative FTP connections, which is useful for BIG-IP units that do not support encrypted communications.

b global open_ftp_ports enable

The following command closes FTP ports:

b global open_ftp_ports disable

open_ssh_ports

This variable enables or disables ports for SSH access on BIG-IP units that support encrypted communication. The default setting is enable.

The following command opens the SSH port (22) to allow encrypted administrative connections:

b global open_ssh_port enable

The following command closes the SSH port:

b global open_ssh_port disable

open_rsh_ports

This variable enables or disables ports for RSH access, and it is useful for BIG-IP units that do not support encrypted communications, or for connecting to 3-DNS Controllers that do not support encrypted communication. (See the 3-DNS Administrator Guide for more information.)

The default setting is disable.

The following command opens the RSH ports (512, 513, and 514) to allow RSH connections:

b global open_rsh_ports enable

The following command closes RSH ports:

b global open_rsh_ports disable

open_failover_ports

This variable enables or disables network failover when a VLAN has port lockdown enabled.

The following command enables network failover:

b global open_failover_ports enable

The following command disables network failover:

b global open_failover_ports disable

persist map_proxies

The default setting for the map proxies for the persistence variable is enable. The AOL proxy addresses are hard-coded. This enables you to use client IP address persistence with a simple persist mask, but forces all AOL clients to persist to the same server. All AOL clients will persist to the node that was picked for the first AOL client connection received.

The class B networks, 195.93 and 205.188, are mapped to 152.163 for persistence. For example, client 195.93.3.4 would map to 152.63.3.4 for persistence records only. This mapping is done prior to applying the persist mask. Use bigpipe pool persist dump to verify that the mapping is working.

We recommend that in addition to setting this sysctl variable, you set a persist mask of 255.255.0.0 so that all the AOL addresses map to a common address. For example, Table 7.2 is an example of how setting this variable and a persist mask of 255.255.0.0 would map a sample set of client addresses.

Address mapping of sample clients

Sample Client Address

Persist Address

152.44.12.3

195.93.0.0

152.2.99.7

195.93.0.0

205.188.11.2

195.93.0.0

208.33.23.4

208.33.0.0 (non AOL address is not mapped)

persist timer

The following command forces the persistent connection timer to reset on each packet for persistent sessions. This is the default value.

b global persist timer limit

The following command resets the timer only when the persistent connection is initiated.

b global persist timer timeout

Note: For SSL persistence, the timer is always reset on each packet.

persist across_services

When this variable is enabled, all simple persistence connections from a client IP address that go to the same virtual address also go to the same node (matches the client address and the virtual IP address but not the virtual port).

The default setting for this variable is disabled.

persist across_virtuals

When this variable is enabled, all simple persistent connections from the same client IP address are sent to the same node (matches the client IP address but not the virtual address or virtual port the client is using). The default setting for this variable is disabled.

self_conn_timeout

This variable is used as a tracking mechanism for UDP connections. After the number of seconds specified by this variable has expired, the UDP connection terminates. The default value for this variable is 5.

sticky table_limit

This is the maximum number of sticky entries allowed to accumulate on the BIG-IP when using destination address affinity (sticky persistence). When the maximum value is reached, the BIG-IP stops accumulating sticky entries. The default value for this entry is 2048.

verbose_log_level

This variable sets logging levels for both TCP and UDP traffic. Each log level is identified by a level number used in place of the <level> parameter.

The following command turns on port denial logging for both TCP and UDP traffic. This logs TCP and UDP port denials to the virtual server address and the BIG-IP address.

b global verbose_log_level 15

The following command turns logging off altogether:

b global verbose_log_level 0

Setting log levels only for TCP traffic

The following command turns on only TCP port denial logging, which logs TCP port denials to the BIG-IP address.

b global verbose_log_level 2

The following command turns on virtual TCP port denial logging, which logs TCP port denials to the virtual server address.

b global verbose_log_level 8

Setting log levels for UDP traffic

The following command turns on only UDP port denial logging, which logs UDP port denials to the BIG-IP address.

b global verbose_log_level 1

The following command turns on only virtual UDP port denial logging, which logs UDP port denials to the virtual server address.

b global verbose_log_level 4

webadmin_port

Specifies the port number used for administrative web access. The default port for web administration is port 443.

l2_aging_time

Specifies a time period after which dynamic entries in the L2 forwarding table are flushed out if the MAC address is no longer present on the network. The default value is 300 seconds.

-h and -help

b [-h | -help ]

Displays the bigpipe command syntax or usage text for all current commands.

Note: More detailed man pages are available for some individual bigpipe commands. To display detailed online help for the bigpipe command, type: man bigpipe.

interface

b interface <if_name> media <media_type> | show
b interface <if_name> duplex full | half | auto | show
b interface [<if_name>] show [verbose]
b interface [<if_name>] stats reset

Displays names of installed network interface cards and allows you to set properties for each network interface card.

Setting the media type

The media type may be set to the specific media type for the interface card or it may be set to auto for auto detection. If the media type is set is set to auto and the card does not support auto detection, the default type for that interface will be used, for example 1000BaseTX.

Setting the duplex mode

Duplex mode may be set to full or half duplex. If the media type does not allow duplex mode to be set, this will be indicated by an onscreen message. If media type is set to auto, or if setting duplex mode is not supported, the duplex setting will not be saved to the bigip.conf file.

load

b [verify] load [ <filename> | - ]
b [-log] load [ <filename> | - ]

Resets all of the BIG-IP settings and then loads the configuration settings, by default from the /config/bigip.conf and /config/bigip_base.conf files.

For testing purposes, you can save a test configuration by renaming it to avoid confusion with the boot configuration file. To load a test configuration, use the load command with the <filename> parameter. For example, if you renamed your configuration file to /config/bigtest.conf, the command would be:

b load /config/bigtest.conf

The command checks the syntax and logic, reporting any errors that would be encountered if the command executed.

You can type b load - in place of a file name, to display the configuration on the standard output device.

b save -

Use the load command together with the verify command to validate the specified configuration file. For example, to check the syntax of the configuration file /config/altbigpipe.conf, use the following command:

b verify load /config/altbigip.conf

The -log option will cause any error messages to be written to /var/log/bigip in addition to the terminal.

maint

b maint

Toggles a BIG-IP into and out of Maintenance mode. When in Maintenance mode, a BIG-IP accepts no new connections, but it does allow existing connections to complete.

The maint command interactively prompts you to enter or exit the maintenance mode.

b maint

If the BIG-IP is already in maintenance mode, the maint command takes the BIG-IP out of maintenance mode. If the BIG-IP is in maintenance mode for more than 20 minutes, that BIG-IP immediately begins to accept new connection requests.

If the BIG-IP has been in maintenance mode for more than 20 minutes, it automatically updates all network ARP caches; this process normally takes a few seconds. However, you can speed the process up by reloading the configuration file, using the following command:

b -f /config/bigip.conf

makecookie

b makecookie <ip_addr:service>

Generates a cookie string with encoding automatically added for cookie persistence Passive mode:

b makecookie <server_address:service> [ > <file>]

This command prints a cookie template similar to the templates shown in Figure 7.2 and Figure 7.3.

Figure 7.2 Sample cookie template

 Set-Cookie:BIGipServer[poolname]=336268299.20480.0000; path=/  

Figure 7.3 Sample cookie template with additional information

 Set-Cookie:BIGipServer[poolname]=336268299.20480.0000; expires=Sat, 01-Jan-2000 00:00:00 GMT; path=/  

To create your cookie using the sample string above, simply enter the actual pool names and the desired expiration date and time.

merge

b [-log] merge [<file_name>]

Use the merge command to load the BIG-IP configuration from <file_name> without resetting the current configuration.

mirror

b mirror <mirror_to_if> interfaces add <if_list>
b mirror <mirror_to_if> interfaces delete <if_list>

For the BIG-IP Application Switch, you can copy traffic from any port or set of ports to a single, separate port. This is called port mirroring. You should attach a sniffer device to the target port, called the mirror-to port, for debugging and/or monitoring.

Creating a port mirror

Creating a port mirror consists of specifying a mirror-to port and adding to it one or more ports (that is, a port list) to be mirrored. The bigpipe syntax for setting up port mirroring is:

b mirror <mirror_to_if> interfaces add <if_list>

For example, you could type the following command:

b mirror 3.24 interfaces add 3.1 3.3 3.10

Deleting interfaces from a port mirror or deleting a port mirror

The bigpipe syntax for deleting interfaces from the port mirror is:

b mirror <mirror_to_if> interfaces delete <if_list>

For example, you could type the following command:

b mirror 3.24 interfaces delete 3.10

The bigpipe syntax for deleting the port mirror is:

b mirror <mirror_to_if> delete

For example, you could type the following command:

b mirror 3.24 delete

monitor

b monitor <monitor_name> '{ use <monitor_template> [<attr> <attr_value>]... }'

b monitor show [all]
b monitor dump [all]
b monitor <name> show
b monitor <name> delete
b monitor <name> enable | disable
b monitor instance <ip>:<service> enable | disable
b monitor instance <ip> enable | disable

Defines a health monitor. A health monitor is a configuration object that defines how and at what intervals a node is pinged to determine if it is up or down. Once a monitor is defined, instances of the monitor are created for a node or nodes, one instance per node, using the bigpipe node command.

For detailed information about setting up the content converter feature, see the BIG-IP Solutions Guide, Chapter 14, Configuring a Content Converter.

ratio

b ratio [<node_ip>] [node_ip> ...] show
b ratio <node_ip> [<node_ip>...] <weight>

For the Ratio load balancing mode, this command sets the weight or proportions for one or more node addresses.

reset

b reset

Use the following syntax to clear the configuration values and counter values from memory:

b reset

Warning: Use this command with caution. All network traffic stops when you run this command.

Typically, this command is used on a standby BIG-IP prior to loading a new /config/bigip.conf file that contains new service enable and timeout values.

For example, you can execute the following commands on a standby BIG-IP:

b reset

b load <filename>

This sequence of commands ensures that only the values set in the <filename> specified are in use.

rule

b rule <rule_name> '{ if ( <expression> ) { <if statement> | <use statement> | discard | <cache statement> | <redirect statement> | <hash statement> <if statement> } [ { else <statement> } ] [ { else if <statement> } ] }'
b rule <rule_name> '{ discard }'
b rule <rule_name> '{ use <pool_name> }'
b rule <rule_name> '{ cache ( <expression> ) { origin_pool <pool_name> cache_pool <pool_name> [ hot_pool <pool_name> ] [ hot_threshold <hit_rate> ] [ cool_threshold <hit_rate> ] [ hit_period <seconds> ][ content_hash_size <sets_in_content_hash> ] } }'
b rule <rule_name> '{ redirect <redirect URL> }'
b rule <rule name> '{ hash ( variable ) }'
b rule <rule_name> { if '( <statement> ) { use ( <statement> )' } }
b rule <rule_name> { if '( <statement> )' { use '( <statement> )' } else { '( <statement> )' } }
b rule <rule_name> { if '( <statement> )' { use '( <statement> )' } else { '( <discard_statement> )' } }
b rule <rule_name> { if '( <statement> )' { use '( <statement> )' } else { '( <redirect_statement> )' } }
b rule <rule_name> { if '( <statement> )' { use '( <statement> )' } else { '( <cache_statement> )' } }
b rule <rule_name> delete
b rule <rule_name> show

Creates, delete, or display the rules on the BIG-IP. Rules allow a virtual server to access any number of pools on the BIG-IP. Based upon a simple or complex expressio,n a pool can be selected through a rule. For more detailed information about using rules, see Rules, on page 4-49.

Note: Before you define a rule, you must define the pool or pools that you want the rule to reference.

Creating a rule

Rules are generally added to an existing bigip.conf file. Note that the rule body should not be enclosed with single quotes in the bigip.conf file. For example:

Figure 7.5 A rule typed into the bigip.conf

 rule cgi_rule {    
if ( http_uri ends_with "cgi" ) { use ( cgi_pool ) }
else { use ( another_pool ) }
}

In this example, if the http_uri string ends with "cgi", then the members of pool cgi_pool are used. Otherwise, the members of pool another_pool are used.

If the rule is defined on the bigpipe command line, you can either surround each pair of parentheses in single quotation marks ('), or place a pair of single quotation marks around the braces. These two methods of defining a rule on the command line are shown as follows:

b rule <name> if '{ <if_stmt> | <use_stmt> | <discard_stmt> | <redirect_stmt> | <cache> }'

Or, you can type the same rule using the following syntax:

b rule <name> if { '(<if_stmt>)' | '(<use_stmt>)' | '(<discard_stmt>)' | '(<redirect>)' | '(<cache>)' }

For example:

b rule simply_red { if '(client_addr == 10.12.12.10)' { use '(pool_A80)' } }

b rule simply_redder '{ if (client_addr == 10.12.12.10) { use (pool_B80) } }'

Associating a rule with virtual server

Associate a rule with a virtual server using the following format:

bigpipe virtual 10.20.2.101:http use rule cgi_rule

Delete a rule

Delete a rule using the following format:

bigpipe rule cgi_rule delete

Display rules

Display all rules using the following syntax:

bigpipe rule show

Or to display a specific rule:

bigpipe rule <rule name> show

save

b save [ <filename> | - ]
b base save [ <filename> | - ]

Writes the current BIG-IP configuration settings from memory to the configuration files named /config/bigip.conf and /config/bigip_base.conf. (/config/bigip.conf stores high level configuration settings, such as pools, virtual servers, NATs, SNATs, and proxies. /config/bigip_base.conf stores low level configuration settings, like, VLANs, non-floating self IP addresses, and interface settings.)

You can type b save <filename>, or a hyphen character (-) in place of a file name, to display the configuration on the standard output device.

b [base] save -

If you are testing and integrating BIG-IP units into a network, you may want to use multiple test configuration files. Use the following syntax to write the current configuration to a file name that you specify:

b [base] save <filename>

For example, the following command saves the current configuration from memory to an alternate configuration file named /config/bigip.conf2.

b save /config/bigip.conf2

self

b self <addr> vlan <vlan_name | vlangroup_name> [ netmask <ip_mask> ][ broadcast <broadcast_addr>] [unit <id>]
b self <addr> floating enable | disable
b self <addr> delete
b self <addr> show
b self show
b self <addr> snat automap enable | disable

Defines a self IP address on a BIG-IP or 3-DNS system. A self IP address is an IP address mapping to a VLAN or VLAN group and their associated interfaces on a BIG-IP or 3-DNS system. A one true self IP address is assigned to each interface on the unit as part of first time boot configuration, and also a floating (shared) self IP address for units in a redundant pair. Additional self addresses may be created for health checking, gateway failsafe, routing, or other purposes. These additional self addresses are created using the self command.

service

b service <service> [<service>...] limit <limit>
b service <service> [<service>...] tcp enable | disable
b service <service> [<service>...] timeout tcp <timeout>
b service <service> [<service>...] udp enable | disable
b service <service> [<service>...] timeout udp <timeout>
b service [<service>... ] show
b service [<service>... ] stats reset

Enables and disables network traffic on services, and also sets connection limits and timeouts. You can use port numbers or service names (for example, www, http, or 80) for the <service> parameter. Note that the settings you define with this command control the service for all virtual servers that use it. By default, all services are disabled.

A port is any valid port number, between 0 and 65535, inclusive, or any valid service name in the /etc/services file.

snat

b snat map <orig_ip> [...<orig_ip>] to <snat_ip><snat_ip> [unit <unit ID>] [netmask <ip>] [arp disable] [vlan <vlan_name_list> disable]
b snat map default to <snat_ip> [unit <unit ID>] [netmask <ip>]

b snat <snat_ip> [...<snat_ip>] vlans enable all
b snat <snat_ip> [...<snat_ip>] vlans show
b snat map <vlan_name> to auto
b snat <snat_ip> [...<snat_ip>] arp [enable|disable]

Defines one or more addresses that nodes can use as a source IP address when initiating connections to hosts on the external network. Note that clients cannot use SNAT addresses to connect directly to nodes.

stp

b stp <stp_name> interfaces add <if_list> | all
b stp <stp_name> hello <interval>
b stp <stp_name> max_age <interval>
b stp <stp_name> forward_delay <interval>
b stp <stp_name> interfaces delete <if _list>
b stp <stp_name> enable|disable

The BIG-IP IP Application Switch provides Spanning Tree Protocol (STP) implementation for loop resolution in configurations where one or more external switches is connected in parallel with the BIG-IP. This feature allows you to configure two or more interfaces on the platform as an STP domain. For interfaces in the STP domain, the spanning tree algorithm identifies the most efficient path between the network segments, and establishes the switch associated with that path as the root. Links forming redundant paths are shut down, to be re-activated only if the root fails.

The STP domain should contain all ports that are connected in parallel to an external switch where there are nodes on the link capable of generating or receiving traffic. You will want a second domain if there is an additional switch or switches connected in parallel with additional BIG-IP interfaces.

trunk

b trunk <controlling_if> define <if_list>
b trunk [<controlling_if>] show [verbose]
b trunk [<controlling_if>] stats reset

The trunk command aggregates links (individual physical interfaces) to form a trunk. This link aggregation increases the bandwidth of the individual NICs in an additive manner. Thus, four fast Ethernet links, if aggregated, create a single 400 Mb/s link. The other advantage of link aggregation is link failover. If one link in a trunk goes down, traffic is simply redistributed over the remaining links.

A trunk must have a controlling link and acquires all the attributes of that controlling link from Layer 2 and above. Thus, the trunk automatically acquires the VLAN membership of the controlling link but does not acquire its media type and speed. Outbound packets to the controlling link are load balanced across all of the known-good links in the trunk. Inbound packets from any link in the trunk are treated as if they came from the controlling link.

A maximum of eight links may be aggregated. For optimal performance, links should be aggregated in powers of two. Thus ideally you will aggregate two, four, or eight links. Gigabit and fast ethernet links cannot be placed in the same trunk.

For more information on interface naming, refer to Interface naming conventions, on page 3-2.

unit

b unit [show]
b unit peer [show]

The unit number on a system designates which virtual servers use a particular unit in an active-active redundant configuration. You can use the bigpipe unit command to display the unit number assigned to a particular BIG-IP. For example, to display the unit number of the unit you are on, type the following command:

b unit show

To display the unit number of the other unit in a redundant system, type in the following command:

b unit peer show

Note: If you use this command on a redundant system in active/standby mode, the active unit shows as unit 1 and 2, and the standby unit has no unit numbers.

Tip: The bigpipe unit peer show command is the best way to determine whether the respective state mirroring mechanisms are connected.

verbose

b verbose virtual_server_udp_port_denial
b verbose virtual_server_tcp_port_denial
b verbose bigip_udp_ort_denial
b verbose bigip_tcp_port_denial

Used to modify the verbose log level. This command is an alternative to using the bigpipe global verbose command.

Table 7.6 defines the command and shows the equivalencies.

bigpipe verbose and global verbose command equivalencies

verify

b [log] verify <command...]
verify load [<filename> | -]

Parses the command line and checks syntax without executing the specified command. This distinguishes between valid and invalid commands

Use the verify command followed by a command that you want to validate:

b verify virtual 10.10.10.100:80 use pool my_pool

The command checks the syntax and logic, reporting any errors that would be encountered if the command executed.

Use the verify command together with the load <filename> command to validate the specified configuration file. For example, to check the syntax of the configuration file /config/altbigpipe.conf, use the following command:

b verify load /config/altbigip.conf

The vlan command defines VLANs, VLAN mappings, and VLAN properties. By default, each interface on a BIG-IP or 3-DNS system is an untagged member of a VLAN. The lowest-numbered interface is assigned to the external VLAN, the interface on the main board is assigned to the admin VLAN, and all other interfaces are assigned to the internal VLAN.

If the tag number specified when defining a VLAN is 0, the vlan command creates an empty VLAN.

The vlangroup command defines a VLAN group, which is a grouping of two or more VLANs belonging to the same IP network for the purpose of allowing L2 packet forwarding between those VLANs.

The VLANs between which the packets are to be passed must be on the same IP network, and they must be grouped using the vlangroup command. For example:

b vlangroup network11 { vlans add internal external }

A self IP address must be assigned to the VLAN group using the following command:

b self <ip_addr> vlan network11

L2 forwarding must be enabled for the VLAN group using the VLAN proxy_forward attribute. This attribute is enabled by default when the VLAN group is enabled.
