Hi,

 

On our S5320-32X-EI I need to remove an outer vlan for traffic we receive from one of our providers. There are two inner vlans, one needs to be forwarded in a VLL l2circuit and another vlan needs to terminate on a vlan interface on the switch. Anyone knows a working configuration for this?

I have a solution, hope it can help.

1. remove the outer VLAN on the downstream switch, this is easy to implement on the downstream switch, just added the outer VLAN as untagged mode. so, the outer VLAN will be removed when the packets is sent out from the interface.

2. configure 2:1 VLAN mapping on switch, map the 2 inner VLAN to the first inner VLAN, the second inner VLAN is terminated.

you can have a try.
