calling-number-avp cevlan-offset

Function

The calling-number-avp cevlan-offset command configures an LAC to add an offset to the CE-VLAN ID (inner VLAN ID) of ICRQ packets to be sent.

The undo calling-number-avp cevlan-offset command restores the default configuration.

By default, no offset is added to the CE-VLAN ID of ICRQ packets.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

If packets sent from different DSLAMs have the same CE-VLAN ID, and the CE-VLAN ID must be identified in the ICRQ packets to be sent by the LAC, run the calling-number-avp cevlan-offset command to configure an offset for the CE-VLAN ID.

Prerequisites

The calling-number-avp cevlan-offset command takes effect only after the CE-VLAN ID to be encapsulated in ICRQ packets has been specified in the calling-number-avp format include cevlan command.

Configuration Impact

After this command is run, the LAC adds an offset to the CE-VLAN ID and then encapsulates the CE-VLAN ID to the ICRQ packets. For example, if the CE-VLAN ID of user access packets is 30, and the calling-number-avp cevlan-offset 20 command is run, the CE-VLAN ID of 50 is encapsulated in the ICRQ packets.

If a VLAN ID is greater than 4094 after an offset is added, the offset is not added for the CE-VLAN ID in ICRQ packets.

Example

# Configure an LAC to add an offset of 20 to the CE-VLAN ID of ICRQ packets.
