Trunk only passes traffic when one cable connected.

Guys

I have a wierd one.

I have switch A (Procurve 2530) host VLAN 1020 - User Data network

I have Switch B (Procurve 2626 default vlan only - Server network

I have created a LACP trunk between them using the 1000SX ports (2 x Fibre ports used)

I only get connectiving between a workstation on switch A (VLAN1020) and server on switch B (Default VLAN) when one of the fibres is connected.  If i connect both together the connection drops.

I am thinking this is a vlan issue because if i create VLAN1020 on switch A and put the trunk ports and workstation port on this VLAN connectivity works with both fibre ports connected in the trunk.

Any ideas?

What are your IP's? I believe these are layer 2 switches and if so you need a router in order to send and receive information via cross-vlan traffic. Not so versed in HP switches but with Cisco switches this is the case.

Can you post your configuration for both switches?

I'm sure we can get this to work.
