Users Guide
During the next authentication attempt, the system does not allow any attempt to login since maximum VTY sessions
have reached and hence no clear-line option.
NOTE: If the maximum number of VTY lines are more than the concurrent sessions and the same user is attempting to
login second time or more, the system displays the Maximum concurrent sessions for the user reached
message. You are allowed to clear the existing session and login. If you do not want to clear any of the existing session,
the system does not allow any attempt to login since maximum concurrent sessions have reached even though more
VTY lines are available. You are allowed to login as a different user as more VTY lines are available.
The following example enables you to clear your existing login sessions.
DellEMC(config)#login concurrent-session clear-line enable
