Overriding VLAN Base Profile Assignments Overview

You can also use the profile vlan override bulk-config command to assign an overriding profile to a single VLAN ID or double-tagged S-VLAN ID that exists within a bulk-configured VLAN subrange. The VLAN ID subrange that encompasses the major interface must have been previously configured with the vlan bulk-config command for use by a dynamic VLAN subinterface. After you assign the overriding profile, the router uses the information in this profile instead of the information in the previously assigned base profile to create any subsequent VLAN dynamic subinterface columns on the specified VLAN major interface, as long as they match the VLAN or S-VLAN specified in the override.

The overriding profile, like the original base profile, can include VLAN attributes, nested profile assignments, and individual characteristics for dynamic upper-interface encapsulation types.

Overriding the base profile assignment for a VLAN with a profile enables you to create a special profile for a subscriber in a DSLAM. For example, you can use the overriding profile to create dynamic VLAN subinterfaces for subscribers with an S-VLAN ID of 200 and a VLAN ID of 100.

You can also use an overriding profile with debugging attributes to troubleshoot problems with VLAN dynamic subinterface columns.

Note: See JunosE Release Notes, Appendix A, System Maximums for information about the maximum number of overriding profile assignments currently supported per chassis.
