Today's post ties together with the previous one. The show users command displays information about the active lines on the device. This command displays the line number, connection name, idle time, hosts (including virtual access interfaces), and terminal location. An asterisk (*) indicates the current terminal session.
Router# show users
Line User Host(s) Idle Location
0 con 0 idle
* 2 vty 0 user1 idle 0 SERVICE1.CISCO.COM
The show users all command specifies that all lines are displayed, regardless of whether anyone is using them.
Router# show users all
Line User Host(s) Idle Location
* 0 vty 0 user1 idle 0 SERVICE1.CISCO.COM
1 vty 1
2 con 0
3 aux 0
4 vty 2
The clear line command is simply used to close a specified virtual terminal (VTY) session. This is especially useful if you have open idle sessions due to the no exec-timeout command from the previous post. Example:
SW1#show users
Line User Host(s) Idle Location
* 0 con 0 idle 00:00:00
2 vty 0 idle 00:05:50 10.1.1.2
3 vty 1 idle 00:01:57 10.1.1.3
4 vty 2 idle 00:01:54 10.1.1.4
Interface User Mode Idle Peer Address
Let's clear the connection originating from 10.1.1.3. This can be done either using the line number or the vty number.
SW1#clear line ?
<0-6> Line number
async-queue Clear queued rotary async lines
aux Auxiliary line
console Primary terminal line
vty Virtual terminal
Option 1:
SW1#clear line 3
[confirm]
[OK]
SW1#
SW1#show users
Line User Host(s) Idle Location
* 0 con 0 idle 00:00:00
2 vty 0 idle 00:07:01 10.1.1.2
4 vty 2 idle 00:02:56 10.1.1.4
Interface User Mode Idle Peer Address
Option 2:
SW1#clear line vty 1
[confirm]
[OK]
SW1#show users
Line User Host(s) Idle Location
* 0 con 0 idle 00:00:00
2 vty 0 idle 00:09:18 10.1.1.2
4 vty 2 idle 00:05:13 10.1.1.4
Interface User Mode Idle Peer Address
The host originating the session will receive a message that the connection was closed.
