Cisco to Nortel VLAN Config

[billy1tech]

Hey

I have connected a Linksys SRW2024 to a Nortel 5510 via fibre uplink ports. Both sides are trunk ports.

I have created VLAN 1 (default) and VLAN 20 on both switches. I can communicate from switch to switch in VLAN 1 but I cannot communicate from switch to switch in VLAN 20.

I setup 2 ports for testing 1 is in VLAN 1 only and the other is in VLAN 20 only. VLAN 1 & 20 are on both uplink ports.

What have I missed?

What VLAN 20 IP addresses do you have?
What is routing between VLANs 1 & 20?

Check the tagging/untagging config of the VLANs on the interfaces.
I suppose you should have the Nortel interface set to
- "UntagPVIDOnly"
- VLAN1 as PVID
- member of both VLANs
(that's *3* seperate bits of config on a Nortel to make a .1q trunk).

I guess the Linksys .1q trunk config is a lot more obvious - just make sure it has the untagged VLAN1 and tagged VLAN20 the same so it matches with the Nortel.
