VLANs

A VLAN is a grouping of separate networks that allows those networks to

behave as if they were a single local area network, whether or not there is a

direct ethernet connection between them.

BIG-IP offers several options that you can configure for a VLAN. These

options are summarized in Table 3.2.

Option Description

Create a default VLAN

configuration

Use the Setup utility to create a default VLAN configuration.

Create, rename, or delete

VLANs

Create, rename, or delete a VLAN.

Configure packet access to

VLANs

Through an option called tagging, you can direct packets from multiple VLANs to a

specific BIG-IP interface, or direct traffic from a single VLAN to multiple interfaces.

Manage the L2 forwarding

table

You can edit the L2 forwarding table to enter static MAC address assignments.

Create VLAN groups Create a VLAN group to allow layer 2 packet forwarding between VLANs.

Set VLAN security You can set port lockdown by VLAN.

Set fail-safe timeouts You can set a failsafe timeout on a VLAN. You can use a failsafe timeout to trigger

fail-over in a redundant system.

Set self IP addresses You can set one or more self IP addresses for VLANs.

Set MAC masquerade You can use the MAC masquerade to set up a media access control (MAC) address

that is shared by a redundant system.
