Step 2 interface pw-ether id
Example:
RP/0/RSP0/CPU0:router(config)# interface PW-Ether1
Configures the PWHE interface and enters the interface configuration mode.
Step 3
ipv4 address ip-address subnet-mask (or) ipv6 address ipv6-prefix/prefix-length
Example:
RP/0/RSP0/CPU0:router(config-if)# ipv4 address 40.1.1.2 255.255.255.0
Sets the IPv4 or the IPv6 address of the main interface.
Step 4 attach generic-interface-list interface_list_name
Example:
RP/0/RSP0/CPU0:router(config-if)# attach generic-interface-list pw_he
Attaches the generic interface list to the interface.
Step 5
interface pw-ether id.subintfid
Example:
RP/0/RSP0/CPU0:router(config-if)# interface PW-Ether1.1
Configures the PWHE sub-interface and enters the sub-interface configuration mode.
Step 6 ipv4 address ip-address subnet-mask (or) ipv6 address ipv6-prefix/prefix-length
Example:
RP/0/RSP0/CPU0:router(config-if)# ipv4 address 40.1.1.2 255.255.255.0
Sets the IPv4 or the IPv6 address of the subinterface.
Step 7
encapsulation dot1q value
Example:
RP/0/RSP0/CPU0:router(config-subif)# encapsulation dot1q 1
