The CNS switch showed the following in its log: May 24 21:31:26.315 CDT: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk TenGigabitEthernet0/10 VLAN847. May 24 21:31:26.315 CDT: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking TenGigabitEthernet0/10 on VLAN0847. Inconsistent port type. May 24 22:49:51.831 CDT: %SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking TenGigabitEthernet0/10 on VLAN0847. Port consistency restored. May 25 00:57:45.614 CDT: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk TenGigabitEthernet0/10 VLAN847. May 25 00:57:45.614 CDT: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking TenGigabitEthernet0/10 on VLAN0847. Inconsistent port type. I added a "spanning-tree bpdufilter enable" on the port that points toward the main CNS switch to solve the problem. This solved the problem for now. But, it might be nice if the technical committee could come up some technical guidelines for spanning-tree that will work for MICE.
