Cisco Systems CCNA 2 Disconnecting and suspending Telnet sessions, Advanced Telnet operation

4.2.3 Disconnecting and suspending Telnet sessions

Network administrators may need to establish multiple Telnet sessions. The keystroke Ctrl- Shift-6and then the letter X can be used to suspend a current Telnet session. The suspend feature can be used to establish an additional Telnet session to another device. The show sessions command displays a numbered list of current Telnet sessions like the following example.

Conn Host		Address	Byte Idle		Conn Name
1	lab-a	192.168.10.1	0	0	lab-a
* 2	lab-e	192.168.10.1	0	0	lab-e

A connection can be resumed by selecting the corresponding number.

The disconnect command will terminate a specific Telnet session.

The procedure for disconnecting a Telnet session is as follows:

•Enter the disconnect command.

•Follow the command with the name or IP address of the router.

•Example: Denver> disconnect paris

The procedure for suspending a Telnet session is as follows:

•Press Ctrl-Shift-6and then the letter X.

•Enter the name of the router or IP address of the next connection.

Students often think that the Ctrl-Shift-6, then X sequence will terminate a Telnet session. They need to understand that this only suspends the session. They also need to know how to resume and terminate a session

4.2.4 Advanced Telnet operation

A user may have multiple Telnet sessions open at the same time. The number is limited by the session limit. The user can switch between these sessions with the Ctrl-Shift-6and then X key sequence. To resume a Telnet session, the resume command with the session id may be used. The connection id of all open Telnet sessions can be viewed with the show sessions command.

Command	Purpose
Ctrl-Shift-6 then X	Escapes the current connection and
	returns to the EXEC prompt
resume	Makes the connection

The resume [session number] command can be used to resume a Telnet session. The process id of a session can also be entered to resume the session.
