[c-nsp] me-3600 docs and drops

[Spyros Kakaroukas]

1) I can only assume it's a typo and they mean SVI instead of EFP. You can have different service instances on different ports belonging to the same bridge-domain, or even different service-instances on the same port ( assuming different encapsulation obviously ). Just remember that if it's matching tagged traffic, you need to pop all the tags before you can terminate it on an SVI.

2) No idea, never tried to match on ethertype in the past. I'd try a newer release though.

My thoughts and words are my own.

Kind Regards,

Spyros

I'm reading the docs on my shiny new ME-3600X [1]  and i see this:

The switch supports IP routing and multicast routing for bridge domains, including Layer 3 and Layer 2 VPNs, using the SVI model. There are the limitations:...

   - You must configure SVIs for bridge-domain routing.
   - The bridge domain must be in the range of 1 to 4094 to match the
   supported VLAN range.
   - There can be only one EFP in the bridge domain.


This last bit seems like a pretty serious limitation to me, so off to the
lab:

Sure enough, I am unable to ping the SVI or across the switchports.  Then I remove the "etype ipv4" restriction (leaving simply "encapsulation untagged
") and it works fine.  I couldn't find any bug directly related  So I have two questions:
1) exactly what do they mean by "There can be only one EFP in the bridge domain."
2) why would "etype ipv4" drop packets that clearly are ipv4?  (icmp echo request,  TCP3389  etc.)


Cheers,
Chris
