Hello community,
We have a couple of 2960S switches in our environment stacked in pairs. I have enabled traps related to the stack:
snmp-server enable traps stackwise port-change
snmp-server enable traps stackwise new-master
snmp-server enable traps stackwise stack-mismatch
snmp-server enable traps stackwise new-member
snmp-server enable traps stackwise member-removed
and traps are supposed to be sent to the server:
snmp-server host ip_address community_string.
Although most configured traps (linkup/linkdown etc) are sent from this switch, stack related traps are never sent.
We also noticed that for all 2960S we have the following value:
ciscoStackWiseMIBObjects.cswGlobals.cswEnableStackNotifications.0:false
Which means:
"This object indicates whether the system generates the
notifications defined in this MIB or not. A value of
'false' will prevent the notifications from being sent."
This is regardless of the IOS running on the stack...
According to Cisco the specific MIB is supported by c2960s-universalk9-mz.122-55.SE3.bin which is one of the IOS running on some of the stacks and not by c2960s-universalk9-mz.122-55.SE2.bin (running on some other switches). I would have thought that at least for the stacks running the 1st IOS 12.2(55)SE3 the value should have been true.
Any thoughts? Is there something that needs to be enabled for the traps to be sent? Does the value of cswEnableStackNotifications.0 need to be true for traps to be sent?
Thank you in advance,
Katerina
