Hi,

In what case i use the command down-when-looped command in cisco router.

The router serial interface become looped (i dont khnow why ) and i must restart the patton modem to desactivate the loop. Can i use this command to desactivate the loop automaticly.

Thanks for your Help

You use this command to tell the router to regard looped interface as down. In this case router choose another path to route packets via dynamic routing or via another static route. Route, which points to interface which is down is automatically removed from routing table.

Hello,

It is OK. But my problem is :

I search a command to desactivate the router interfec to become looped when there is many interrupts in modem. This command (ignore-hw local-loopback ) resolve my problem, but i dont understand how i uses it .

Thanks

You use this command when modem experiences short outages and a result of it interface can come into loopback state. The signal to enter the loopback state comes into interface through pin #18 of RS-232. The command you specified makes interface ignore any signal on pin #18, so interface will not go into loopbacked state.
