Cisco ASR 9000 Series

Configuring Source Bypass Filter
Perform this task to add a source bypass filter.
SUMMARY STEPS
1. configure
2. interface type interface-path-id.subinterface l2transport
3. Do one of the following:
• encapsulation dot1q vlan-id or
• encapsulation dot1ad vlan-id or
• encapsulation untagged or
• encapsulation dot1ad vlan-id dot1q vlan-id or
• encapsulation dot1q vlan-id second-dot1q vlan-id or
4. rewrite ingress tag translate translate 1-to-1 dot1q vlan-id symmetric
5. ethernet egress-filter disable
6. ethernet source bypass egress-filter
7. Use the commit or end command.
DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters Global Configuration mode.
Step 2 interface type interface-path-id.subinterface l2transport
Example:
RP/0/RSP0/CPU0:router(config)# interface GigabitEthernet 0/2/0/4.1 l2transport
Enters subinterface configuration mode and enables Layer 2 transport mode on a port and enters Layer 2 transport
configuration mode.
Step 3 Do one of the following:
• encapsulation dot1q vlan-id or
• encapsulation dot1ad vlan-id or
• encapsulation untagged or
• encapsulation dot1ad vlan-id dot1q vlan-id or
• encapsulation dot1q vlan-id second-dot1q vlan-id or
Example:
RP/0/RSP0/CPU0:router(config-subif)#
encapsulation dot1q 10
or
RP/0/RSP0/CPU0:router(config-subif)#
encapsulation dot1ad 10
