I am provisioning a new 3750 switch stack (ip x.x.x.200) to replace an old stack (ip x.x.x.100). I'm having issues with the stack-ports on the new stack. Both stacks are 3750-E 48 ports (all switches in each stack are the same hardware running the same IOS code). My SNMP monitoring is showing stack ports 1-2 and 2-1 as down, so I'm investigating. Below (at the bottom..."SHOW OUTPUT") you find the output from the commands "show switch stack-ports summary", "show switch", and "show version". I've tried disabling and reenabling the stack ports with:
switch 1 stack port 2 disable
switch 2 stack port 1 disable
switch 1 stack port 2 enable
switch 2 stack port 1 enable
but (with console logging) I get the following:
000138: *Mar 1 08:17:14.052 EST: % Disabling stack port not allowed with current stack configuration.
000139: *Mar 1 08:17:34.150 EST: % Disabling stack port not allowed with current stack configuration.
I have not, since we have servers connected to that and to do so would bring down the uplink for the top switch (since only the 1 stacking link is active) But I can probably test it early in the morning.
Also, the stack had been up with no issues at all for a couple of days. Switch 2 had been the master (it is not currently) when yesterday afternoon, my coworker unplugged the power cord of the master (bottom or switch 2) and re routed the power cord. Pretty sure he did not touch the stacking cables, but could a problem develop from turning off the master in the stack? When I saw the alert, which began right after he did that, the stacking link was reporting an issue. I noticed that 2 was the master, and changed it (switch 1 priority 15, wr mem, reload) then since I usually like the top switch to be master - makes things neater. This morning some servers have been moved to the new stack with the stacking issues, so now it's harder just to reload or change the switch without causing service interruptions. *sigh*
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
