Creating a Trunk/Tagged Vlan port

Ryrager — Thu, 08 Oct 2009 20:14:13 GMT

Hi All

Wer have a new 5406zl this is configured to have VLAN 1 and 90 passed through port A2 to a Cisco 2950 on port 1 on the 2950 switch.

This is all set however I can only seem to get Vlan 90 traffic passing between the 2 on that port? any ideas? Configs below.

The 2950 has ports 18,19,20,21 set to be VLAN 90 for our phones.

So we want A2 to be Tagged in both Vlan 1 and 90 on the 5406zl and want fa0/1 to be cisco trunked on Vlan 1 and 90.

Now why aren't they working as expected?

Thanks for any help.

Ryan

I think your problem is that the Cisco doesn't expect vlan-1 to be tagged. Where the Procurve does.

The "native" vlan on the cisco must match the "untagged" on the procurve.
So untag vlan1 on the procurve or change the native vlan on the cisco so vlan1 is tagged there.

Some Cisco switches have a dot1q-all-tagged mode, don't know if the 2950 does...

suggestion : next time put config in attachement, makes the thread more readable.
