Q: I have several hanging telnet / vty sessions that I need to kill on my Cisco 6509 router. Which command will murder those connections?

Actually, our 6509 has two MSFC modules (redundant), a switch module, a firewall service module, an intrusion detection module and a network analysis module.
Wow that is like the Swiss-army knife of Layer 3 switches! 
If you want to keep the inactive vty lines from happening you can use guy's suggestion of exec-timeout on the vty lines to time out inactive sessions.
actually a 6509 with msfc and SLB is considered a layer7 switch. But at its heart it is a switch that routes at layers 3 and 4 with the capability to be an application (layer7) switch.
Architectually though – it is a switch, but then again any really good router is a "switch" at its core. There are two separate planes in a high end router…a control plane and a switching plane. Control tells it where to go, switching is the actual act of moving/reproducing the frame on the egress port.

I believe my co-worker used the exec-timeout method to kill the sessions after a reload failed to kill them. However, since we killed those sessions, I had another hung session and was able to kill it using your clear line method with no problem.

Re:Actually, our 6509 has two MSFC modules (redundant), a switch module, a firewall service module, an intrusion detection module and a network analysis module. It's primary function is as a router and firewall vs. a switch. Thanks for the help BTW. guy's method works great.
Re:Cisco states not to turn off your router or switch..only in emergencies…also 6509 is a switch not a router

Re:you can also use exec-timeout (in line config mode on the vty) to kill inactive sessions…
Re:clear line # (where # is the vty line)
Course there's always the reload command :laugh:
