Question : Redundency problem with cisco 6513 and Cisco 3560 Switches

Dear Experts


I have the following set up 2 Cisco 6513 Switches for full redundency,

Cisco 6513 Switches (2 for redundency (IOS Version 12.2(17d)SXB11) and they are connected to cisco 3550 Switches (Version 12.1(22)EA6).


BB01 (6513) is connected to BB02 (6513) with two fiber connections one is active & other is in blocking state.
Before we had one SPF module ( WS-X6724-SFP) in each back bone switch to connect the work gorup switches. Each work group switch is connected from both back bone switches for redundency. Recently we got the same SPF module to expand our network. And we bought Cisco 3560G Switches. After installing new SPF modules in both backbone Switches things are working fine. I am facing problem when ever I am adding a new cisco 3560 switch to the network. When I connect the redundent link the network is hanging and following errors are generated in the backbone switches

Error in BB01

DC-MDF1-WG1#

Now looking at the above configuration can please tell me where is the mistake , as far as my guess I have some problems with spanning tree (spanning-tree vlan 1-1005 priority 24576 in BB01) and (spanning-tree vlan 1-1005 priority 28672 in BB02).

Please let me know how to over come this problem

Answer : Redundency problem with cisco 6513 and Cisco 3560 Switches

I think there shold be some problem with ether chanels so please remove them  & check.


cheers

Yasir
