Cisco logging
Hi Experts,
I have installed several cisco stacks with each 2 x 2960X
Now I had a complete outage, the stacks were running but no uplinks.
The uplinks also were green.
Is it possible to check old logs from cisco 2960X switches ?

Can you ID what that MAC address is? That log indicates the uplinks were bouncing due to that flap. I am assuming those uplinks are in a Port channel.

Hi, in my stack I have 2 switches.
Each switch has one fiber uplink.
And since now the uplinks are not in port channel.

Can you help me with the port channel command of two uplinks ?
Now I had a complete outage, the stacks were running but no uplinks.Please define "Complete outage". Are you saying that all the users were complaining of no network connectivity? No internet?
on my core switch I found this logThat entry was three days ago.
and the next log was :Are those the only entries in the logs? This second entry was from today but does the time correspond to the "outage"? Address flapping between ports is typically a result of spanning-tree not blocking a redundant port. What are T1/1/1 and T1/1/3 connected to?
ASKER
with outage I mean no internet
ASKER
no the log is bigger, check here:

Strange is the lack of 3 days and the time shift.
I never shifted the time, from where this came ?

with outage I mean no internetIt would be helpful to understand the topology. Can you post a diagram? Without knowing what's connected to the ports that have address flapping, all we can do is make guesses.

Here is the picture...

the switches are stacked, see here...
Can you show the config of the uplinks for each TenGig and the core switch?
Something isn't right and need to see more of the picture.

!ASKER
maybe the problem is that each stack has two uplinks to the core without any portchannel group.
right ?
right ?

tonight I will change the config and create a port channel of the uplinks.

Done thanks to all and I hope the errors are gone.
