Core issue
When an attempt is made to add a new Virtual LAN (VLAN) interface to the Firewall Services Module (FWSM), it does not show as active. When this issue occurs the vlan xx is not assigned to this FWSM module error message appears.
Resolution
Complete these steps in order to determine why the interface does not show as active:
-
Issue the show running-config command from the switch, review the output, and determine the interface to which the VLAN is associated. For example:
interface FastEthernetx/x
description XXXX XXXX (optional)
!--- displays the description given to the port
logging event link-status (optional)
shutdown
!--- reveals whether the port is administratively shutdown
speed 100
!--- displays the port speed
duplex full
!--- displays the duplex status
no snmp trap link-status (optional)
switchport
switchport access vlan yy
!--- displays the vlan number associated with the port
switchport mode access
In this example, the port is shutdown. In such situations, try to activate the port.
- The vlan xx is not assigned to this FWSM module error message appears if the FWSM is not able to download the VLANs into its database.
In order to resolve such issues, delete the VLAN and re-add it to the VLAN group.
