redundant network setup for hp 3800 switches

[matt8520]

Hey Everyone,

I need some help with setting up a redundant links between a stackable 3800 switch and two patch panel switches which are 3800.

So what I have so far:

I have two trunks on the stackable switch:

trk1 1/1 & 2/1 LACP

trk2 1/2 & 2/2 LACP

On both of the patch panel switches I have trk1 ports 1 & 2 using LACP

When I turn on trk1 1/1 - I get traffic moving on the switch

When I turn on trk 2 2/2 - I get traffic moving on the other switch

When I turn on trk1 1/2 - I get traffic moving but then the switch blocks port 2/2

The event viewer tell me that it is being block by STP.

Any help with this would be great both HP support and myself are stump.

I'm guessing that the "patch panel switches" are inter-connected.

Have you reduced your spanning-tree priority on the 3800 stack?

Put "descriptions" on your interfaces (eg, "Link to PP Switch1", etc...).

Then show us a copy of your switch config and a "show lldp inf rem" from the stacked 3800.
