[c-nsp] me3400 EVC config help needed

[Adam Vitkovsky]

Hi William,

Regarding the l2prot tunnel
On the me3400 UNI port -I believe the protocol tunneling is off by default
so the l2protocol-tunnel cmd is needed 

Regarding the EVC requirement on me3400
So I guess it's not possible to configure cfm without the service keyword
right?
Like just:
ethernet cfm mep domain testnet mpid 1


Regarding the qinq stuff
I believe there are two options depending on your setup

Either you double tag all frames on the me3400:
(required when other customers are being connected from the pre-aggregation
me3400)
me3400 port style:
interface FastEthernet0/3
switchport access vlan 10 <=== gonna be used as outer tag
switchport mode dot1q-tunnel <=== tunnel all customer vlans
l2protocol-tunnel

me3400 EVC style:
interface FastEthernet0/3
service instance 1 ethernet cust1
  encapsulation default <==== match any
  l2protocol-tunnel
  rewrite ingress tag push dot1q 10 symmetric <===add the outer tag(not sure
it's possible on me3400)


76xx:
interface GigabitEthernet3/1
service instance 3 ethernet
  encapsulation dot1q 10 second-dot1q 1-4094  <=== match outer 10 inner any


Or you can double tag on 76xx:
(when the me3400 is basically a CPE/NTU)
me3400:
interface FastEthernet0/3
service instance 1 ethernet cust1
  encapsulation default <==== match any
  l2protocol-tunnel

76xx:
interface GigabitEthernet3/1
service instance 3 ethernet
  encapsulation default  <=== match any
  rewrite ingress tag push dot1q 10 symmetric <===add the outer tag 
  l2protocol-tunnel

Hi all

I can't find a solution on the net and whilst TAC is currently on the
case!!!

Maybe someone can throw me a quick fastball.

I want to have the following setup

CE----me3400---76xx---mpls network

I want my uni port on the me3400 to accept any CVLAN tags and untagged
frames.
I want all CVLANs to get stuck into SVLAN 10 and sent up to the NNI port.
I also want to l2-protocol tunnel any CVLANs.

I want to use the EVC setup as I have the future requirement for CFM/OAM
stuff.

I have the following at the moment:
But doesn't seem to be working:

Me3400:

ethernet cfm ieee
ethernet cfm global
ethernet cfm domain testnet level 4
service cust1 vlan 10
  continuity-check
  continuity-check interval 1s
!
ethernet evc cust1                          <== do these have to be the
same?
oam protocol cfm svlan 10 domain testnet !
ethernet lmi global

interface FastEthernet0/3
switchport trunk allowed vlan none
switchport mode trunk
speed 100
duplex full
ethernet cfm mep domain testnet mpid 1 service cust1
  cos 7
ethernet uni id END1
ethernet uni bundle all-to-one
service instance 1 ethernet cust1
  ethernet lmi ce-vlan map 1-4094,untagged !
!

interface GigabitEthernet0/1
port-type nni
switchport mode trunk
!

76xx:
interface GigabitEthernet3/1
no ip address
no cdp enable
spanning-tree bpdufilter enable
service instance 3 ethernet
  description Customer-10
  encapsulation dot1q 10 second-dot1q 1-4094
  xconnect x.x.x.x 1227 encapsulation mpls !
end

Is this the correct config?  I cannot find any decent documentation on this
and how all the commands interact.

Many thanks
