| There may be several concurrent Telnet sessions open. A user may switch back and forth between these sessions. The number of open sessions that are allowed at one time is defined by the session limit command.

The 2500 series routers are limited to five sessions. Multiple Telnet sessions can be used and suspended by using the Ctrl-Shift-6, then x sequence. The session can be resumed by using the Enter key.

The connection ID is shown by using the show sessions command.
