Additional Base Network Configuration
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.
