Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Limit concurrent login sessions

To avoid an unlimited number of active sessions on a switch for the same user ID, limit the number of console and remote connections. Log in from a console connection by cabling a terminal emulator to the console serial port on the switch. Log in to the switch remotely through a virtual terminal line, such as Telnet and SSH.

• Configure the maximum number of concurrent login sessions in CONFIGURATION mode.

  OS10(config)# login concurrent-session limit number

  • limit number — Sets the maximum number of concurrent login sessions allowed for a user ID, from 1 to 12; default 10.

Configure concurrent login sessions

OS10(config)# login concurrent-session limit 4

If you log in to the switch after the maximum number of concurrent sessions are active, an error message displays. To log in to the system, close one of your existing sessions.

OS10(config)# login concurrent-session limit 4

Too many logins for 'admin'.
