3750 stack - stuck

[coltengine]

Hello,

i have 4 3750 in stack:

                                           H/W   Current
Switch#  Role   Mac Address     Priority Version  State 
----------------------------------------------------------
 1       Member 001a.a1a3.d280     10     0       Ready               
*2       Master 001a.a1c1.f200     15     0       Ready               
 3       Member 04fe.7f5e.f200     1      1       Ready               
 4       Member 04fe.7f5e.8880     1      1       Ready               

after a PDU failure, switch nr 1 and nr 3 are gone away...

after that, all stack stopped his switching and routing works. when i turned on the powered OFF switches, i must shut down and reactivate all portchannel versus cisco 7600 router ( i founded the ports in blocking state ), and also vertus other cisco switch.

Any idea ?

Hi,

First I need to understand how your connectivity is established between cisco 7600 router and the Stack 3750 Master.

If you have direct connectivity with the Switch Stack number 1 and 3 then the scenario is ideal.

And If my understanding is not correct then kindly share the logs, interface status at both the end at the  time of the issue occcured. As well I need the Show stack output when there was the problem.

remote command ( switch no.) sh log for all the stack switch.
