Chapter 2 CLI Command Reference
vlan translation
vlan translation
Sets the VLAN translation constant for the network port side, and specifies whether to increment or
decrement the received VLAN tag. The subscriber port side automatically performs the reverse
operation. Use the no form of this command to disable vlan translation for this port (sets the value to
zero).
vlan translation {increment | decrement} value value
no vlan translation

Command Modes Linecard Interface Configuration
Command History This table includes the following release-specific history entries:
Usage Guidelines The configured translation is applied to the network port side. The reverse operation is automatically
performed at the subscriber side.
For example, if "increment 5" is defined, at the network port the VLAN is incremented by 5, and at the
subscriber port the VLAN is decremented by 5.
In this case, the network side VLAN tags might be 105, 205, 305, and the subscriber side the VLAN tags
would then be 100, 200, 300.
Make sure that the same VLAN translation constant is configured for all SCE platforms in the system.
Note the following limitations when VLAN translation is enabled:
• LIC Bypass not supported – In general, installations using the VLAN translation feature should rely
on cutoff on failure and at upgrade (use redundant SCE platform).
• STP hazard – VLAN translation may interfere with Spanning Tree Protocol. This should be taken
in consideration when deploying the solution.
Authorization: admin
Examples The following example specifies a VLAN translation constant of 20 for the network port side.
