Device |
Specifies the discovered BIG-IP device for the virtual
server. |
Name |
Specifies the name of the virtual server. |
Description |
Specifies a description for the virtual server. |
Partition |
Specifies the partition or path to which the virtual server belongs. Only users with
access to a partition can view the objects (such as the self IP address) that it contains.
If the virtual server resides in the Common partition, all users
can access it.
Note: Although pre-populated with Common
(default), you can set the partition by replacing Common with a
unique name for the partition. The partition with that name must already exist on the
BIG-IP device. If it does not exist, then, at deployment, the deployment will fail. No
whitespace is allowed in the partition name.
|
Type |
Specifies the network service provided by this virtual server. The default type is
Standard. The possible types are listed.
Note: Not all
properties are valid for all types. When you specify the type, certain properties may
become available or unavailable.
-
Standard: Specifies a virtual server that directs client
traffic to a load balancing pool and is the most basic type of virtual server. When you
first create the virtual server, you assign an existing default pool to it. From then
on, the virtual server automatically directs traffic to that default pool.
-
Forwarding (Layer 2): Specifies a virtual server that shares
the same IP address as a node in an associated VLAN. This type of virtual server has no
pool members to load balance.
-
Forwarding (IP): Specifies a virtual server like other virtual
servers, except that the virtual server has no pool members to load balance. The virtual
server simply forwards the packet directly to the destination IP address specified in
the client request.
-
Performance (HTTP): Specifies a virtual server with which you
associate a Fast HTTP profile. Together, the virtual server and profile increase the
speed at which the virtual server processes HTTP requests.
-
Performance (Layer 4): Specifies a virtual server with which
you associate a Fast L4 profile. Together, the virtual server and profile increase the
speed at which the virtual server processes Layer 4 requests.
-
Stateless: Specifies a virtual server that accepts traffic
matching the virtual server address, and load balances the packet to the pool members
without attempting to match the packet to a pre-existing connection in the connection
table. New connections are immediately removed from the connection table. This addresses
the requirement for one-way UDP traffic that needs to be processed at very high
throughput levels, for example, load balancing syslog traffic to a pool of syslog
servers. Stateless virtual servers are not suitable for processing traffic that requires
stateful tracking, such as TCP traffic. Stateless virtual servers do not support iRules, persistence, connection mirroring, rateshaping, or SNAT
automap.
-
Reject: Specifies that the BIG-IP system rejects any traffic
destined for the virtual server IP address.
-
DHCP: Specifies a virtual server that relays Dynamic Host
Control Protocol (DHCP) client requests for an IP address to one or more DHCP servers,
and provides DHCP server responses with an available IP address for the client.
-
Internal: Specifies a virtual server that supports
modification of HTTP requests and responses.
|
Source |
Specifies an IP address or network from which the virtual server accepts traffic.
The virtual server accepts clients only from one of these IP addresses. For this setting
to function effectively, specify a value other than 0.0.0.0/0 or
::/0 (that is, any/0, or
any6/0). In order to maximize utility of this setting, specify the
most specific address prefixes covering all customer addresses and no others. Specify the
IP address in Classless Inter-Domain Routing (CIDR) format: address/prefix, where the
prefix length is in bits: for example, for IPv4: 10.0.0.1/32 or
10.0.0.0/24, and for IPv6: ffe1::0020/64 or
2001:ed8:77b5:2:10:10:100:42/64. |
Destination |
Specifies the destination IP address information to which the virtual server sends
traffic.
- If the destination type is set to Host, specify only the IP
address in the Address field. Specify the IP address in CIDR
format: address/prefix, where the prefix length is in bits: for example, for IPv4:
10.0.0.1/32 or 10.0.0.0/24, and for IPv6:
ffe1::0020/64 or
2001:ed8:77b5:2:10:10:100:42/64. The defaults for DHCP are
255.255.255.255 (IPv4 Default) and ff02::1:2 (IPv6 Default). You
can also select Other to specify another destination
address.
- If the destination type is set to Network, specify both the IP
address in the Address field, and the network mask in the
Mask field. Specify the mask address in CIDR format as you did
the IP address.
|
Service Port |
Type a service port or select a type from the list. When you select a type from the
list, the value in the Service Port field changes to reflect the
associated default, which you can change. |
State |
Specifies whether the virtual server and its resources are available for load
balancing. The default is Enabled. |
Connection Mirroring |
Specifies that the system mirrors connections on each member in a redundant
configuration. Connection mirroring is the process of duplicating connections from the
active system to the standby system. Enabling this setting ensures a higher level of
connection reliability, but it may also have an impact on system performance. |
Protocol |
Specifies a network protocol name that you want the system to use to direct traffic
on this virtual server. The default is TCP. If the
Type is set to Performance (HTTP), the
network protocol is set to TCP. If the Type
is set to DHCP, the Protocol property is not
available. The following are valid network protocol keywords.
-
*All Protocols: Specifies that the virtual server supports all
network protocols. This setting is not available when you select the
Type of Standard.
-
TCP: Specifies that the virtual server supports the TCP
protocol, defined in RFC 675.
-
UDP: Specifies that the virtual server supports the UDP
protocol, defined in RFC 768.
-
SCTP: Specifies that the virtual server supports the Stream
Control Transmission Protocol (SCTP) protocol, defined in RFC 4960.
-
Other: Provides the ability to specify another protocol. This
setting is not available when you select the Type of
Standard.
|
Protocol Profile (Client) |
Specifies that the selected profile is a client-side profile. The list contains
entries for each defined client protocol profile for the protocol selected in the
Protocol property. |
Protocol Profile (Server) |
Specifies that the selected profile is a server-side profile. Options are:
(Use Client Profile), and entries for each already defined server
protocol profile. The default is (Use Client Profile). |
VLAN and Tunnel Traffic |
Specifies the VLANs and tunnels for which the virtual server is enabled or disabled.
The default is All VLANs and Tunnels.
-
All VLANs and Tunnels: Specifies that the virtual server is
enabled on all VLANs and tunnels configured on the system.
-
Enabled on: Specifies that the virtual server is enabled on
the VLANs and tunnels specified in the Selected list.
-
Disabled on: Specifies that the virtual server is disabled on
the VLANs and tunnels specified in the Selected list.
|
Default Pool |
Specifies the pool name that you want the virtual server to use as the default pool. A
load balancing virtual server sends traffic to this pool automatically, unless an iRule
directs the server to send the traffic to another pool instead. Options are:
None, and entries for each already defined pool. The default is
None.
|
DoS Profile |
Specifies the DoS profile to use, if enabled. Options are:
Disabled and Enabled. The default is
Disabled. When Enabled is selected, choose
a DoS profile from those displayed in the Profile area. DoS profiles are defined using the
Shared Security DoS Profiles panel. |
HTTP Profile |
Specifies the HTTP profile for managing HTTP traffic. Options are:
None, and entries for each already defined HTTP profile. The
default is None.
Note: Adapt profiles cannot be used
when the http-transparent profile is selected.
|
SIP Profile |
Specifies the Session Initiation Protocol (SIP) profile for the system to use for this
virtual server. Options are: None, and entries for each already
defined SIP profile. The default is None.
|
DNS Profile |
Specifies the Domain Name System (DNS) profile for the system to use for this virtual
server. Options are: None, and entries for each already defined
DNS profile. By selecting dns and specifying
53 for the Service Port, you can create a
virtual server that acts as a DNS listener. The default is None.
If you select None for a currently configured listener, the object
is no longer a DNS listener.
|
Log Profiles |
Specifies the log profile to be used. To select a log profile, use the arrow keys to
move the log profile to the Selected column. To remove a selected
log profile, use the arrow keys to move the log profile to the
Available column. Log profiles listed in the
Available column are defined using the Shared Security Logging
Profiles
panel. |
