It is possible that all of the VTY session have been used up (line vty 0 4); if this is the case then a clearing (clear line vty x) of the sessions should resolve the issue.

Sears Sent: Wednesday, July 28, 2004 11:54 AM To: Nanog Subject: Loss of Telnet Capability to 6509 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...? ****************************************** Richard J.
