PurposeCommand or Action
Example:
Router(config-if-srv)# encapsulation dot1q 100
second-dot1q 200
Specifies the tag manipulation that is to be performed
on the frame ingress to the service instance.
rewrite ingress tag {push {dot1q vlan-id | dot1q vlan-id
second-dot1q vlan-id | dot1ad vlan-id dot1q vlan-id} | pop {1
| 2} | translate {1-to-1 {dot1q vlan-id | dot1ad vlan-id}| 2-to-1
Step 6
dot1q vlan-id | dot1ad vlan-id}| 1-to-2 {dot1q vlan-id
second-dot1q vlan-id | dot1ad vlan-id dot1q vlan-id} | 2-to-2
{dot1q vlan-id second-dot1q vlan-id | dot1ad vlan-id dot1q
vlan-id}} [symmetric]
Example:
Router(config-if-srv)# rewrite dot1q double symmetric
Binds an attachment circuit to a pseudowire, and
configures an Any Transport over MPLS (AToM)
static pseudowire.
xconnect peer-ip-address vc-id {encapsulation {l2tpv3 [manual]
| mpls [manual]} | pw-class pw-class-name }[pw-class
pw-class-name] [sequencing {transmit|receive| both}]
Example:
Router(config)# xconnect 1.1.1.1 100 pw-class
vlan-xconnect
Step 7
Configures a maintenance endpoint (MEP) for a
domain.
cfm mep domain domain-name [up | down] mpid mpid-value
[cos cos-value]
Example:
Router# cfm mep down mpid 100 domain Core
