crs can support double 802.1Q vlan tag and untag?

now set 802.1Q vlan & service vlan can use。but double 802.1Q vlan can‘t to set,how to do?

Hi, a few days ago I had the same problem.

The default service tag type on crs is 802.1ad, but you can overwrite this configuration to 802.1Q for each port.

/interface ethernet switch port
set ether1 ingress-service-tpid-override=0x8100 egress-service-tpid-override=0x8100

In my case this works perfect.

thanks for you rep.i will try this way :slight_smile:
