Hi all,
I'm trying to configure a interface with two dot1q tags but I can't do it.
I think thats is because my line card doesn't support it but I can't find any doc to confirm it.
I have a 7606-S chassis with two WS-SUP32-GE-3B, one WS-X6548-RJ-45 and one WS-X6516A-GBIC.
When I try to configure a subinterface in any line module with the command "encapsulation dot1Q X second-dot1q Y" the router doesn't accept second-dot1q part of the command,
Router(config-subif)#do sh run interface GigabitEthernet2/1.2
Building configuration...
Current configuration : 38 bytes
!
interface GigabitEthernet2/1.2
end
Router(config-subif)#interface GigabitEthernet2/1.2
Router(config-subif)#encapsulation dot1Q 3 ?
native Make this as native vlan
<cr>
I tried it in a interface of each module and always is the same output.
After, I have tried to use service instance but I can't set encasulation under service instance configuration part,
Router(config)#interface GigabitEthernet6/5
Router(config-if)#service instance 1 ethernet
Router(config-if-srv)#?
Ethernet EFP configuration commands:
default Set a command to its defaults
description Service instance specific description
ethernet ethernet
exit Exit from ETHER EFP configuration mode
ipv6 IPv6 interface subcommands
mac Commands for MAC Address-based features
no Negate a command or set its defaults
shutdown Take the Service Instance out of Service
snmp Modify SNMP service instance parameters
The easy way is upgrade hardware but is not a choice now...
Anybody know if it's possible do it with my hardware config?
Thanks in advance.
David.

Hello.
Yes, this kind of MPLS configuration is supported on SIP400, ES20/ES40 LC, but ES20/40 requires SUP720, so SIP400 is your only chose.
If you configure xconnect under service instance, you need SIP400 V2 SPA; if you configure under sub-interface -> just SIP400. In this case SIP400 is customer-facing LC.
Also you have an option to configure xconnect under interface VLAN -> SIP400 should be CORE-facing LC.

I believe only ES20/40 line cards and some Ethernet modules in a SIPxxx card can support the type of configuration your looking to perform.
