We posted this to cisco-nsp but someone suggested posting it here as
well...
We have a 6509 running a SUP720 in IOS only mode (no cat os).
At around 4am this morning, we lost our ability to telnet to the router.
Running a tcpdump shows that the router never responds to the telnet
request.
All functions and interfaces on the router seem fine (bgp, etherchannel,
ibgp, vtp, hsrp) and I can console into the sup with no problems at all,
we just cannot telnet into it. The CPU is at around 6%.
I have checked all access lists on the router, none were added/removed
or modified on line vty that would cause this problem. All logging
appears normal.
We are running Version 12.2(17a)SX3.
Anyone have a similar problem or know how to check or restart the telnet
process on the router without a reload...?
