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.
