console-login

Enables the user to be prompted for a user ID and password on the physical console. This is useful for security situations. If you do not con®gure any administrative users and you enable this feature, the following message appears:

Warning: Console login is disabled until an administrative user is added.

Attention: Before enabling console login, save the con®guration with console login disabled. If login authentication is set to a remote server using Radius or Tacacs+ and the router is unable to reach the authentication server, then access to the router is denied. By disabling the console login, a lock-out situation is prevented.

interface interface#

Causes the interface to be enabled after issuing the restart command. command.

modem-control [carrier-wait or ring-wait] [service1 or service2]

Sets up the router for login on the physical console, if the physical console is connected to the router through a modem. Before using this command, be sure to:

vSet your modem for auto-answer.

vVerify that the console baud rate is equal to the modem baud rate.

vVerify that the cable connecting the modem to the router is con®gured correctly.

vTurn echo off by using the ATE0 command.

vRun in quiet mode by using the ATQ1 command.

vVerify that any necessary jumpers are set. Refer to your router's User's Guide more information.

The router automatically hangs up the modem when you log out. Also, if your modem becomes disconnected from the router while you are using it, the router logs you out.

Specify the service port for both the enable modem-controlcarrier-waitand the enable modem-controlring-waitcommands. For routers with two service ports, also specify to which service port you connected the modem, either service1 or service2. To enable both service ports, enable them separately.

Note: No console connection can be made with the router after enabling modem control unless you clear all con®guration and restart the router.

You can tell the router to wait for the carrier-detect signal from the modem before sending Request to Send. This is the standard method of modem control.
