Command
Step 8
rewrite ingress tag pop {1 | 2} symmetric
Step 9
end
Step 10
show ethernet service instance

Use the no forms of the commands to remove the service instance, encapsulation type, or bridge domain
or to disable the rewrite operation.

Configuration Examples

Configuring a Service Instance

Switch (config)# interface gigabitethernet0/1
Switch (config-if)# switchport mode trunk
Switch (config-if)# switchport trunk allowed vlan none
Switch (config-if)# service instance 22 Ethernet [name]
Switch (config-if-srv)# encapsulation dot1q 10
Switch (config-if-srv)# bridge-domain 10

Encapsulation Using a VLAN Range

Switch (config)# interface gigabitethernet0/1
Switch (config-if)# service instance 22 Ethernet
Switch (config-if-srv)# encapsulation dot1q 22-44
Switch (config-if-srv)# bridge-domain 10

Two Service Instances Joining the Same Bridge Domain

In this example, service instance 1 on interfaces Gigabit Ethernet 0/1 and 0/2 can bridge between each
other.
Switch (config)# interface gigabitethernet0/1
Switch (config-if)# service instance 1 Ethernet
Switch (config-if-srv)# encapsulation dot1q 10
Switch (config-if-srv)# bridge-domain 10
Switch (config)# interface gigabitethernet0/2
Switch (config-if)# service instance 1 Ethernet
Switch (config-if-srv)# encapsulation dot1q 10
Switch (config-if-srv)# bridge-domain 10

Purpose
(Optional) Specify that encapsulation modification to occur on
packets at ingress.
• pop 1—Pop (remove) the outermost tag.
• pop 2—Pop (remove) the two outermost tags.
• symmetric—Configure the packet to undergo the reverse of
the ingress action at egress. If a tag is popped at ingress, it is
pushed (added) at egress.
Although the symmetric keyword appears to be optional,
Note
you must enter it for rewrite to function correctly.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
