Hi everyone. I'm having an strange issue with one Nexus 7k: A few days ago it suddenly started to fail connections through SSH/telnet. We haven't changed anything relevant, and we haven't found any reasons regarding this problem.
When we try to ssh to it, we get the message: "connection timeout". We can ping without any problem to the Nexus, and in general, it works fine.
When we connect through console port, we don't see any relevant logs; we type "show users", and lines are not busy:
DS-CORE-NX7K# show users
NAME LINE TIME IDLE PID COMMENT
cpsadmin ttyS0 Feb 13 08:35 . 22327 *
We check the processes, and we don't see anything either. It doesn't have a login block nor an ACL. The walkaround is to reset the SSH feature:
(conf-t)# no feature ssh
(conf-t)# feature ssh
After restarting this feature, it keeps working a few days, and then it fails again. This is a cisco Nexus7000 C7010 running version 6.2(2a)
What can we do to troubleshoot this issue?. I cannot see anything relevant in the logs, and I couldn't find a debug that could be useful, or a bug related to this NX-OS version.
Thanks.
