Issue with EVC and MAC learning

[mplatise]

Hi,

I have a testing scenario that seems no to work and I don't find eny clue.

On switch 3800-B I have configured this two ports. To the port  0/8 I have connected a host with IP address and MAC f0f7.55cf.6201.

interface GigabitEthernet0/8
switchport access vlan 20
end

interface GigabitEthernet0/7
switchport trunk allowed vlan none
switchport mode trunk
service instance 1 ethernet
  encapsulation dot1q 10 second-dot1q 11
  rewrite ingress tag pop 2 symmetric
  bridge-domain 20

Then I connect the interface 0/7 of this switch to the switch 3800-A to port 0/8. Port is configured as follows.

  bridge-domain 15 interface GigabitEthernet0/8
switchport trunk allowed vlan none
switchport mode trunk
service instance 1 ethernet
  encapsulation dot1q 1-4094 second-dot1q 1-4094
  bridge-domain 15

The connectivity is going further, but issue is happening here.

I see MAC adress of the host on the 3800-B Gi0/8,

  20    f0f7.55cf.6201    DYNAMIC     Gi0/8

but I do not see this MAC at the port and service instance on the switch 3800-A ??

Do I have missed something or there is any issue with double tagging on this platform ?

I appreciate quick response and thanks for any hint.

I am still not clear with the requirement. What exactly are you trying to achieve?

If you can draw a topology with the required result, I would be able to help you with the configuration.

Hi Waris,

the whole configuration consists of some other links and connections, so I might have had a loop somewhere. I completelly changed the design and it works.

Thank you for your engagement and best regards.
