 Clearing Terminal Connections
When a terminal connects to the network device, the corresponding terminal line is occupied. Run the show user command
to display the connection status of these terminal lines. If you want to disconnect the terminal from the network device, run
the clear line command to clear the terminal line. After the terminal lines are cleared, the related connections (such as Telnet
and SSH) are interrupted, the CLI exits, and the terminal lines restore to the unoccupied status. Users can re-establish
connections.
