LMS 4.1 Etherchannel member history


We have 2 6509 swithes in VSS mode. There are several portchannels configured between the VSS cores and some Data Center switcehs. Last week we had a power failure so the 6509's were shut down and then powered on when power was restored.

After Powering the 6509's I noticed that one Gigabit Fiber (SFP) uplink that is a member of an etherchannel group was down on one of the 6509. The other members of the same channel (connecting to a data center switch) were oprational as before. Is there a way in LMS 4.1 to see when the last time this inactive member port was up. I want to know if it was up prior to the power failure or not. I tried seeing Reports --> Utilization History (30 days) for the 6509 with the failed interface but the it was not included in the report, although other interfaces in the same module were present.

Is there any other way?

All Help is appreciated


Re: LMS 4.1 Etherchannel member history

One standalone Cat6Ks, the output of "show etherchannel port-channel" should have something along the lines of "Time since last port un-bundled:    00d:10h:20m:58s    TenGigabitEthernet1/5/4". That may work on cat6k VSS too.

With LMS, assuming it's collecting the sufficient level of syslogs from the VSS in question, one can run reports against the Syslog Collector for entries along the lines of "Dec 31 22:35:58.492: %EC-SW1_SP-5-UNBUNDLE: Interface TenGigabitEthernet1/5/4 left the  port-channel Port-channel1".
