  • Page 899: Terminal

    The terminal access feature supports the automatic link teardown function. You can enable the function and configure the teardown time in terminal template view. With this function enabled, if a terminal is disconnected from the router, the terminal enters the state of DOWN, and the router will automatically tear down the TCP connection to the front-end processor (FEP) after the specified time period.

  • Page 900: Bind Vpn-Instance

    (manual link establishment is the default mode). The router establishes a TCP connection to the FEP only after a user enters a character on the terminal, except the special characters for hotkeys and terminals. Special characters are the characters that the terminals process directly, such as <Shift+F2>.
