Chapter 2 CLI Command Reference
vlan
Symmetric and Asymmetric Environments
In a symmetric environment, the same VLAN tags are used for carrying a transaction in the upstream
and downstream directions.
In an asymmetric environment, the upstream and downstream VLAN tags of the same flow might not be
the same.
The Cisco SCE platform is configured by default to work in symmetric environments. The a-symmetric
skip command is needed to allow correct operation of the Cisco SCE platform in an asymmetric
environment. The command instructs the platform to take into consideration that the upstream and
downstream of each flow has potentially different VLAN tags.
Examples The following example shows how to enable VLAN-based classification:
SCE8000>enable 10
Password:<cisco>
SCE8000#config
SCE8000(config)#interface linecard 0
SCE8000(config if)#vlan symmetric classify
SCE8000(config if)#
