Additional Base Network Configuration

BIG-IP® Reference Guide 3-21

feature to configure two or more interfaces on the unit 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. A second domain is called for if there is an additional

switch or switches connected in parallel with additional BIG-IP interfaces.

Use of STP may slow performance significantly, particularly if more than

one STP domain is created, and may have unforeseen effects on complex

networks. It is important to test your STP configuration before placing it

online.

Creating and deleting STP domains

You can create or delete STP domains using the Configuration utility or

from the command line.

To create an STP domain using the Configuration utility

1. In the navigation pane, click Network.

The Network screen opens.

2. Click the STP tab.

The Trunks screen opens.

3. Click the Add button.

4. Configure the STP domain attributes.

5. Click Done.

To create or delete an STP domain from the command line

To create an STP domain from the command line, use the following syntax:

b stp <stp_name> interfaces add <if _list> | all

For example, if you want to create an STP domain named mystp that

contains the interfaces 1.1 and 1.2, type the following command.

b stp mystp interfaces add 1.1 1.2

If you want to create an STP domain named mystp that contains all

interfaces on the BIG-IP, type:

b stp <stp_name> interfaces add all

To delete an STP domain, use the following syntax:

b stp <stp_name> delete

1 2 ... 70 71 72 73 74 75 76 77 78 79 80 ... 425 426
