Configure inner tag+outer tag based VID change policy table
For ingress packets on Access, Trunk, Hybrid and Uplink ports, sometimes we
need to change the VID of outer Tag to different values. Use "dot1q
new-outer-vlan VID translate old-outer-vlan vid inner-vlan v_list" command
to specify the new outer VID, old outer VID and inner Tag list, and use "no
dot1q new-outer-vlan VID translate old-outer-vlan vid inner-vlan v_list"
command to remove the configuration. Please refer to command reference for
detailed commands.
The configuration steps are shown below:
Command Function
