We have always been able to telnet to this switch and now we get : "Could not open connection to the host, on port 23: Connect failed"

I know if I reboot this I will be able to telnet to it, but this is our core switch and I was wondering if there is a why to clear the telnet session without rebooting the switch?

Sounds like your vty (telnet) sessions are all tied up..


Try this..


Connect to console..


rtr1#sho users

Line User Host(s) Idle Location

1 vty 0 jonesmic 172.x.x.x 1w0d 172.x.x.x

* 2 vty 1 jonesmic idle 00:00:00 172.x.x.x


Interface User Mode Idle Peer Address


rtr1#clear line vty 0

[confirm]

[OK]


As you can see I cleared an old hung session..


Then you might want to set the exec-timout under line vty 0 4 to a shorter period..


example;


conf t

line vty 0 4

exec-timeout 20


(sets timeout to 20 minutes)
