Cisco ASR 920 series Configuration Guide Ethernet Router

PurposeCommand or Action
Configures dot1ad NNI, C-port or S-port on the interface.ethernet dot1ad {nni | uni {c-port | s-port}}
Example:
Router(config-if)# ethernet dot1ad nni
Step 4
or
Router(config-if)# ethernet dot1ad uni
c-port
or
Router(config-if)# ethernet dot1ad uni
s-port
Configure an EFP (service instance) and enter service instance
configuration) mode.
service instance number ethernet [name]
Example:
Router(config-if)# service instance 1
Ethernet
Step 5
•
The number is the EFP identifier, an integer from 1 to 4000.
•
(Optional) ethernet name is the name of a previously
configured EVC. You do not need to use an EVC name in a
service instance.
Configure encapsulation type for the service instance.encapsulation {default | dot1q | priority-tagged
| untagged}
Step 6
• default—Configure to match all unmatched packets.
Example:
Router(config-if-srv)# encapsulation dot1q
10
• dot1q—Configure 802.1Q encapsulation. See Encapsulation
for details about options for this keyword.
• priority-tagged—Specify priority-tagged frames, VLAN-ID
0 and CoS value of 0 to 7.
• untagged—Map to untagged VLANs. Only one EFP per port
can have untagged encapsulation.
(Optional) Specify that encapsulation modification to occur on packets
at ingress.
rewrite ingress tag push dot1ad vlan-id [dot1q
vlan-id] symmetric}
Step 7
Example:
Router(config-if-srv)# rewrite ingress tag
push dot1ad 30 symmetric
•
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. This keyword is required for rewrite
to function properly.
• push—Adds a tag to an ingress packet.
• dot1ad vlan-id—Specifies the 802.1 do1ad tag. Valid Vlan ID
range is from 1 to 4094.
• dot1q vlan-id—Specifies the 802.1 do1q tag. Valid Vlan ID
range is from 1 to 4094.
