Limit Concurrent Login Sessions
Dell Networking OS enables you to limit the number of concurrent login sessions of users on VTY, auxiliary,
and console lines. You can also clear any of your existing sessions when you reach the maximum permitted
number of concurrent sessions.
By default, you can use all 10 VTY lines, one console line, and one auxiliary line. You can limit the number of
available sessions using the
login concurrent-session limit
command and so restrict users to that
specific number of sessions. You can optionally configure the system to provide an option to the users to
clear any of their existing sessions.
Restrictions for Limiting the Number of
Concurrent Sessions
These restrictions apply for limiting the number of concurrent sessions:
• Only the system and security administrators can limit the number of concurrent sessions and enable the
clear-line option.
• Users can clear their existing sessions only if the system is configured with the
login concurrent-
session clear-line enable
command.
