Configuring Overriding Profile Assignments for VLAN Major Interfaces

You can assign an overriding profile to a single VLAN major interface within a bulk-configured VLAN subrange.

The overriding profile includes debugging attributes to help you identify and troubleshoot problems with the VLAN dynamic subinterface column created on the specified VLAN ID.

To assign an overriding profile to a VLAN within a bulk-configured VLAN subrange:

1. Configure both of the following:
   • Base profile for the bulk-configured dynamic VLAN on the static VLAN major interface. The VLAN range consists of one or more VLAN subranges.
   • Overriding profile for a dynamic VLAN within a bulk-configured VLAN subrange.

   For information about configuring profiles, see Configuring a Dynamic Interface from a Profile in Configuring Dynamic Interfaces.

2. Create a bulk-configured range of single-tagged VLAN IDs or double-tagged S-VLAN IDs on a static VLAN major interface. The following commands create a bulk-configured VLAN range named myBulkConfig that consists of two VLAN subranges. The first subrange encompasses VLAN IDs 150–250. The second subrange encompasses VLAN IDs 300–500.

   host1(config)#interface gigabitEthernet 4/0.101

   host1(config-if)#vlan bulk-config myBulkConfig vlan-range 150 250
   vlan-range 300 500

3. Assign the previously configured base profile (vlanBaseProfile) to the bulk-configured VLAN range.

   host1(config-if)#profile vlan bulk-config myBulkConfig vlanBaseProfile

4. Assign the previously configured overriding profile to a single VLAN ID or double-tagged S-VLAN ID within the bulk-configured VLAN subrange. The following command assigns the overriding profile overrideVoiceSubscriber to the VLAN ID 202. This VLAN ID exists within the first VLAN subrange (VLAN IDs 150–250) configured in Step 2.

   host1(config-if)#profile vlan override bulk-config myBulkConfig vlan 202 overrideVoiceSubscriber

   The router now uses the information in the overriding profile instead of the information in the base profile to create subsequent VLAN dynamic subinterface columns over this VLAN ID.

5. (Optional) You can assign the same overriding profile to a VLAN ID within the same VLAN range or within a different VLAN range. For example, the following command assigns the overriding profile overrideVoiceSubscriber to the VLAN ID 160. This S-VLAN ID exists within the VLAN subrange configured in Step 2.

   host1(config-if)#profile vlan override bulk-config-name myBulkConfig
   svlan 120 202 overrideVoiceSubscriber

   Note: You can reverse the order of Step 2 and Step 4 with identical results. That is, you can assign the overriding profile to an S-VLAN ID and then assign the base profile to the entire VLAN subinterface.

6. Configure the VLAN major interface to support autodetection of the VLAN dynamic encapsulation type.

   host1(config-if)#auto-configure vlan

7. (Optional) Use the show vlan profile command to verify the overriding profile configuration.
