[VLAN] Vlan 1 in bridge ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi again Peter,

I have got to the bottom of the problem. Thanks very
much for your advice. The problem was not actually
with my bridge - to include vlan 1 i simple created
eth0.1 using vconfig and added it to the bridge. 

The problem lies with the trunk port I am connecting
to. This is setup to trunk all vlans. On closer
inspection however into how 802.1Q works, the native
vlan on a trunk port is not actually tagged. When i
made the native vlan a vlan other than 1, I could see
all the traffic from vlan 1 in by bridge, because it
was now arriving tagged.

I'm using a Cisco 2950 and unfortunately it would seem
there is no way to make it tag the traffic on the
native vlan, this can however be done with other Cisco
models.

Many thanks
Piccalo
