Chapter 10 Configuring Network Access

Configuring Virtual Context VLAN Interfaces

The ACE Appliance Device Manager uses class maps and policy maps to classify (filter) traffic and to

direct it to different contexts. A virtual context uses VLANs to receive packets classified for that context.

Note When you create a new VLAN interface for a virtual context, you can configure one or more VLAN

interfaces in any user context before you assign those VLAN interfaces to the associated user contexts

in a virtual context through the Allocate-Interface VLANs field (see the “Creating Virtual Contexts”

section on page 4-2).

Use this procedure to configure VLAN interfaces for virtual contexts.

Procedure

Step 1 To configure a virtual context, select Config > Virtual Contexts > context > Network > VLAN

Interfaces. The VLAN Interface table appears.

Step 2 Click Add to add a new VLAN interface, or select an existing VLAN interface, and then click Edit to

modify it.

Note If you click Edit, not all of the fields can be modified.

Step 3 Enter the VLAN interface attributes (see Table 10-3). Click More Settings to access the additional

VLAN interface attributes. By default, ACE appliance Device Manager hides the default VLAN

interface attributes and the VLAN interface attributes which are not commonly used.

Note If you create a fault-tolerant VLAN, do not use it for any other network traffic.
