VLL support on S7700

Latest reply: Dec 12, 2014 01:27:38 1735 1 0 0 0


I want to configure Kompella VLL using S7700 switches. When I use VLAN encapsulation everything works (port link-type trunk on PE on both sides).

The problem is that I have VLAN encapsulation on one side (port link-type trunk) and link-type access port on remote.

The VLL connection is up, but there is no communication. Is this config supported, or what else should be configured?

when you connect the trunk port to access port, only two kinds of  packets can get through the access port.

1. VLan tagged packet with the tag number the same as the access vlan number.

2. untagged packet.

Any other tagged packet can't get thruough the access port.

When packets go out from the trunk port, all the packets are tagged except the packet from the native vlan.

I'm not quite sure why you configure the peer port as access mode, maybe you can describe you demands, and we'll find some solution for you.
