7600 second-dot1q & vlan tag manipulation

Hi,

Does anyone know what the hardware requirements are for using config such as "sencapsulation dot1Q 660 second-dot1q 1" or any of the "service instance" commands such as below to manipulate dot1q tags?

Im running 7600 with SIP-400, IOS 12.2(33)SRD and there are no such commands available at the cli. Suspect ES-20 is needed as a minimum but can't see this mentioned in any docs.

interface FastEthernet1/0.660

encapsulation dot1Q 660 second-dot1q 1

OR

interface GigabitEthernet3/0/0

description Sample Configs

!

service instance 1 ethernet

encapsulation untagged

rewrite ingress tag push dot1q 3 symmetric

xconnect 10.30.30.173 2 encapsulation mpls

service instance 10 ethernet

encapsulation dot1q 10

rewrite ingress tag pop 1 symmetric

bridge-domain 500 split-horizon

!

service instance 20 ethernet

encapsulation dot1q 20 second-dot1q 200

rewrite ingress tag pop 1 symmetric

bridge-domain 500 split-horizon

!

service instance 30 ethernet

encapsulation dot1q 20 second-dot1q any

rewrite ingress tag pop 1 symmetric

bridge-domain 500 split-horizon

I just need to pop the service vlan tag. At the moment I'm using a port per service to peel off the outer tag and this approach isn't going to scale.

Appreciate any advice on this.

Cheers

Kent.

Re: 7600 second-dot1q & vlan tag manipulation

Hi Kent,

Just found some information on your issue, I believe this feature is not available on the V1 SPA. Where your theory is correct in your second post.

The feature you are looking for is 802.1ad QinQ termination (stacked VLAN processing)

SPA v2

Hi Kent,

Can you post the complete show version output, I suspect you are not using the right software feature set for your IOS.

Re: 7600 second-dot1q & vlan tag manipulation

Hi Jerry,

I believe - about to test it - that this only works with SPA-v2 interfaces. I was testing with a SPA-v1 interface previously. Is this your understanding? Docs are pretty light on with hardware requirements.

Re: 7600 second-dot1q & vlan tag manipulation

Hi Jerry,

Yes - confirmed as well in the lab. This functionality is supported in the SPA v2 and not the SPA v1.

Difficult info to find.

Cheers

Re: 7600 second-dot1q & vlan tag manipulation

Hi Kent,

This is really true. And the problem is it is hiding inside the hardward product datasheet.

Glad you've figured this out.

jerry
