Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
The symmetric keyword is accepted only when a single VLAN is configured in encapsulation. If a list of
VLANs or a range VLAN is configured in encapsulation, the symmetric keyword is accepted only for push
rewrite operations; all other rewrite operations are rejected.
The pop command assumes the elements being popped are defined by the encapsulation type. The exception
case should be drop the packet.
The rewrite ingress tag translatecommand assume the tags being translated from are defined by the
encapsulation type. In the 2-to-1 option, the "2" means "2 tags of a type defined by the encapsulation command.
The translation operation requires at least "from" tag in the original packet. If the original packet contains
more tags than the ones defined in the "from", then the operation should be done beginning on the outer tag.
Exception cases should be dropped.
Examples The following example shows how to specify the encapsulation adjustment that is to be performed on the
frame ingress to the service instance:
RP/0/RSP0/CPU0:router(config-if)# rewrite ingress push dot1q 200
