setup unidirectional link from router (UDP traffic only)

Hi.

Is it possible to send data from a router to something else using an unidirectional link ?

Like a cable with only the 1,2 pair used.

The data sent from the router are netflow data, UDP only.

I like the cable hack, but the router link stays down, and I don't see how I can force it to go up. (show int will say up, but sho controllers will say link down).

thanks !

Stephane.

Hi, If you want to see the port up, you can use the command keepalive 0 in the interface configuration, but I´m not sure if the router will transmit packets under this condition.

Another option could be an access-list denying all the traffic coming to the interface.

Regards
