Part of managing a BIG-IP®
system involves configuring and maintaining a certain set of system properties. These properties consist of general platform properties such as the BIG-IP system host name, IP address, and passwords for its system administrative accounts.
From the Platform screen of the Configuration utility, you can configure
general platform properties and user administration settings. Note that you can also configure many of these properties and settings by running the Setup utility, prior to running the Configuration utility.
The following procedure provides the basic steps for configuring
platform-related general properties. Following the procedure is a description of each property, along with additional details you might need for completing step 4 of the procedure.
| |For the Management Port
setting, type an IP address, a netmask, and a route address.
| |In the Host Name
box, type a unique name for the BIG-IP system.
Every BIG-IP system has a management port, or interface, named MGMT.
The management interface
is a special interface that the BIG-IP system uses to receive or send certain types of administrative traffic. You cannot use the management interface for normal traffic that is slated for load balancing. Instead, the BIG-IP system always uses the TMM switch interfaces for that type of traffic. TMM switch interfaces
are those interfaces controlled by the Traffic Management Microkernel (TMM) service.
Configuring the management interface of a BIG-IP system means assigning
an IP address to the interface, supplying a netmask for the IP address, and specifying an IP address for the BIG-IP system to use as a default route. The IP address that you assign to the management interface must be on a different network than the self IP addresses that you assign to VLANs. Note that specifying a default route for the management interface is only necessary if you intend to manage the BIG-IP system from a node on a different subnetwork.
To configure the management interface, you use the Management Port
setting on the General screen. There are no default values for this setting.
For procedural information on configuring the management interface, see
the BIG-IP® Systems: Getting Started Guide
. For information on the way that the TMM service affects the management interface, see the description of the TMM service in Chapter 24, Configuring BIG-IP System Services
Every BIG-IP system must have a host name. Using the Host Name
setting, type a fully qualified domain name for the BIG-IP system. An example of a host name is mybigip.win.net
Every BIG-IP system must have a host IP address. This IP address can be
the same as the address that you used for the management port, or you can assign a unique address.
To assign the host IP address, locate the Host IP address
setting and select either Use Management Port IP Address
or Custom Host IP address
. The default value is Use Management Port IP Address
You can use the general properties screen to specify whether the BIG-IP
system is to operate as a single device or as part of a redundant system. The default value is Single Device
To designate the BIG-IP system as being part of a redundant system, use the High Availability
setting to select Redundant Pair
. Then use the Unit ID
setting to select the unit ID that you want to assign to the BIG-IP system (1
Another of the general platform properties that you can specify is the time
zone. The many time zones that you can choose from are grouped into these categories: Africa, America, Antarctica, Arctic, Asia, Atlantic, Australia, Europe, Indian, and Pacific.
To set the time zone, use the Time Zone
setting to select a time zone from the list. Select the time zone that most closely represents the location of the BIG-IP system you are configuring.
Part of managing platform-related properties is maintaining passwords for
the system account. You can also configure the system to allow certain IP addresses to access the BIG-IP system through SSH.
When you ran the Setup utility on the BIG-IP system, you set up some
administrative accounts. Specifically, you set up the root
accounts. The root
accounts are for use by BIG-IP system administrators.
Users logging in with the root
account have terminal and browser access to the BIG-IP system. By default, users logging in with the admin
account have browser-only access to the BIG-IP system.
You can use the General screen of the platform properties to change the
passwords for root
accounts on a regular basis. To change a password, locate the Root Account
or Admin Account
setting, and in the Password
box, type a new password. In the Confirm
box, retype the same password. For more information, see To configure general platform properties
When you configure SSH access, you enable user access to the BIG-IP
system through SSH. Also, only the IP addresses that you specify are allowed access to the system using SSH.
To configure SSH access, locate the SSH Access
setting and click the Enabled
box. Then use the SSH IP Allow
setting to select either * All Addresses
or Specify Range
, which allows you to specify a range of addresses for which access is allowed.
