Joining procurve switches together

[amaze_it]

Thanks for the quick reply.  I have tried as you suggested, and turned on DHCP for one of the other VLANs - it does indeed pick up an IP fine; so i'm starting to suspect it's specifically to do with the phones.  I noticed that when i set up the trk port it's automatically added "spanning-tree Trk1 priority 4" to both configs - i've tried the global spanning tree disable command but it's still there.  Could this be the cause (bearing in mind my previous information about the IP phones)?

i've attached the config for both switches (ip addresses removed) - any help would be appreciated. 

The phones are clearly struggling to get DHCP as they are reporting "DHCP Timeout" and then restarting when connected to the new switch.

You missed on Tagging "Trk1" on Core Switch for Vlan 2

can't believe i missed that....you are indeed correct.  added to VLAN2 on main switch and phone immediately came online.

Thanks you once again :)
