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. Configuring Concurrent Session Limit To configure concurrent session limit, follow this procedure: • Limit the number of concurrent sessions for all users. CONFIGURATION mode login concurrent-session limit number-of-sessions Example of Configuring Concurrent Session Limit The following example limits the permitted number of concurrent login sessions to 4. Dell(config)#login concurrent-session limit 4 66 Management
