Hi,

you do usually not need a command for it. When the link goes down it will be removed.

The question is what you call severe errors. In case there are transmission errors in the Sp network, but your interfaces are OK, then you can only detect this with active probing like keepalives.

Try "ppp quality " on your contributing links. Have a look at

Did it help? Then rate it please.

Hi Martin,

Thanks for your response.

The errors I referred to are interface errors: CRC, input/output, runts, and etc.

I think "ppp quality " will do the trick. Let's say the link quality drops below my configured threshold and the link got shutdown. Will this link be automatically back in service when the link quality is restored or less than my threshold? Or I must administratively re-enable the interface?

Thanks

Hello,

if the link quality is restored, the link will be restored after a time lag, in order to prevent problems with bouncing links.

Unfortunately I haven´t been able to figure out the length of that time lag...

Regards,

GP
