Router VTY Line Locked up

Answered Question
Jul 14th, 2008

Was running a copy ftp: flash: on this router. The ftp server choked and the ssh session locked up.


Now we have a VTY line which wont free up.


Tried clearing line vty 0, line 322, line tty 322 with no luck. The exec timeout is 20 minutes on the line and we are past that.. Any ideas or a reboot my only option?



RouterA>who

Line User Host(s) Idle Location

vty 322 UserA idle 00:52:20 10.10.10.156

* vty 323 UserB idle 00:00:00 10.10.10.169


Interface User Mode Idle Peer Address

Se0/0/0:0 Sync PPP 00:00:00 10.10.10.2

Hello Jacob,

I would try clear line vty 322 otherwise you can try to clear the tcp session to ip address 10.10.10.156.

Do a sh tcp or a show tcp brief all then take the TCB hex value and use it as an argument for clear tcp


Or you can go via SNMP
