push additional tag to the service

[moods]

Hi,

i have hard time to find how can i push the additional tag to the epipe service.

The customer will send to us a tagged or double-tagged traffic. i want to push additional tag and send the traffic to the other side of the epipe/SDP

example from Cisco

Code: Select all

service instance 8000 ethernet
  encapsulation default
  rewrite ingress tag push dot1q 4000 symmetric

Could you share the topology first, then let me know. what kind of vlan tagging that you use, is it dot1q or qnq

If you are doing something like this:

CE1 ---------------- 7750_1 -------------- 7750_2 ---------------------------- CE2
tagged 100_______ null encap____________ dot1q encap tag 4000 ____________ rx tag 4000.100

example on 7750_1
conf ser ep 100
sap x/y/z create
exit
spoke-sdp 7750_2:100 create

example on 7750_2
conf ser ep 100
sap a/b/c:4000 create
exit
spoke-sdp 7750_1:100 create

7750_1 receives tag 100 but as it is configured as a null port it does not care what tags are in the frame header. As 7750_2 is a dot1q port it will push tag 4000 on to anything it sends towards CE2
