Vlan trunk from 2848 to A5500 Problem
I'm having a problem with a vlan trunk port from my 2848 which is my core switch to a new A5500. My configs are below for both switches if someone would like to help me. I'm pretty clueless on the Comware based devices having spent most of my time with Cisco. Thanks.

Re: Vlan trunk from 2848 to A5500 Problem
It might help if you specified which switchports were being used to patch the two switches together.
Assuming it's port 48 on the Comware switch, as you don't have VLANs 20 and 40 tagged on any interface on the Procurve, these VLANs aren't going to be trunked between them.

Re: Vlan trunk from 2848 to A5500 Problem
Port 45 on the 2848 is connected to the A5500 on port 48 and the 2848 is tagged for Vlans 1,20,40. Access port 13 is not able to see any devices on the 2848.
Thanks.

Re: Vlan trunk from 2848 to A5500 Problem
I think I must be going blind - I didn't see those tagged ports before in the Procurve config...
I know Procurves let you specifiy only tagged VLANs on a trunk, but the Comware I'm pretty sure will always have an untagged VLAN - if you have none specified, it will be VLAN1.
So with Comware like with Cisco, either leave VLAN1 untagged on the Procurve side, or create a dead VLAN to be untagged on both sides of your trunk.
Also, Comware might like it if you declare the untagged VLAN to also be the PVID on the interface.

Re: Vlan trunk from 2848 to A5500 Problem
Also, should
"port link-type access" not appear explicitly on port 13? Or is this not displayed and is implicit?
Also, why is
"port bridge enable" been switched on? I think this is weird Comware stuff that you should leave off.
