Usage Information
You must have either the System Administrator or Security Administrator privileges to configure login concurrent-
session limit or to enable clear-line.
To limit the number of concurrent sessions that any user can have on console, auxiliary, and virtual terminal lines,
use the login concurrent-session limit number-of-sessions command.
If the login concurrent-session clear-line enable command is configured, you are provided with
an option to clear any of your existing sessions after a successful login authentication. When you reach the
maximum concurrent session limit, you can still log in by clearing any of your existing sessions.
Example
The following example shows how to limit the number of concurrent sessions that any user can have to four:
DellEMC(conf)# login concurrent-session limit 4
DellEMC(conf)#
The following example shows how to use the login concurrent-session clear-line enable
command.
DellEMC(conf)# login concurrent-session clear-line enable
DellEMC(conf)#
When you try to log in, the following message appears with all your existing concurrent sessions, providing an
option to close any one of the existing sessions:
$ telnet 10.11.178.14
Trying 10.11.178.14...
Connected to 10.11.178.14.
