Cisco ASR 920 series Configuration Guide Ethernet Router

PurposeCommand or Action
Creates a service instance (an instance of an EVC) on an interface and sets the device into the config-if-srv
submode.
encapsulation untagged dot1q {any | vlan-id [vlan-id [vlan-id]]} second-dot1q {any | vlan-id [vlan-id
[vlan-id]]}
Step 5
Example:
Router(config-if-srv)# encapsulation dot1q 20 second-dot1q 30
Configures the encapsulation. Defines the matching criteria that maps the ingress dot1q, QinQ, or untagged
frames on an interface for the appropriate 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 dot1q vlan-id | dot1ad
Step 6
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 ingress tag pop 2 symmetric
Specifies the tag manipulation that is to be performed on the frame ingress to the service instance.
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}]
Step 7
Example:
Router(config)# xconnect 1.1.1.1 100 pw-class vlan-xconnect
Binds an attachment circuit to a pseudowire, and configures an Any Transport over MPLS (AToM) static
pseudowire.
cfm mep domain domain-name [up|down] mpid mpid-value [cos cos-value]
Step 8
Example:
Router# cfm mep up mpid 100 domain Core
Configures a maintenance endpoint (MEP) for a domain.
