Manual Chapter: Configuring BIG-IP Platform Properties
Manual Chapter
Table of Contents   |   << Previous Chapter   |   Next Chapter >>

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.
When you configure platform properties, you are affecting the operation of the BIG-IP system as a whole, rather than just one aspect of it.
Note: For detailed information on configuring specific features of local traffic management, see the Configuration Guide for BIG-IP® Local Traffic Manager.
The remainder of this chapter describes how to configure and maintain these platform properties, using the BIG-IP Configuration utility.
Note: An alternate way to configure platform is to use either the bigpipe utility or tmsh. For more information, see the Bigpipe Utility Reference Guide or the Traffic Management Shell (tmsh) Reference Guide.
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.
1.
On the Main tab of the navigation pane, expand System, and click Platform.
The General screen opens.
2.
For the Management Port setting, type an IP address, a netmask, and a route address.
3.
In the Host Name box, type a unique name for the BIG-IP system.
4.
Configure all other general property settings as needed.
For more information, see the sections following this procedure, as well as the online help.
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.
Tip: You can also configure the management port using the LCD menu on the IP switch hardware. If you configure the management port using the LCD menu, you do not need to configure the port with the Configuration utility.
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 or 2).
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 and admin accounts. The root and admin 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 and admin 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.
