We are having troubles with one of our cisco 6509 switches (with native IOS) which acts
as MPLS router. We don't get SNMP counter values anymore (at least not
all of them). We have a second identical MPLS router (same model, same
IOS image) which does not have any problems at all,
what we already did:
- os upgrade
In the following graph, you can see that we don't get any counter
values any more (red coloured text): (I am sorry for the language, but
you should be able to get the important part without german skills)
MTRG graph says that this suddenly started in May 2009:
We already checked the changes, but we could not find anything special.
At the moment, we are out of options. We could replace the sup720, but
I am not sure if this has any effect (each 6509 switch as two sup720,
so I guess it would not be a problem).
Any other ideas? Thanks
