Hi,

Can you help me out with my problem, the thing is that I continually get down and up eth1 my wan port. Sometimes after many times of down&up remains down and I have to physically reconnect the cable (cat 5e, 115meters).

Thanks for your assistance

Hi,
115 meters is a bit long for a Cat5e cable, the max length is actually 100m. This could cause the interface to flap like this.
Is there anyway to reduce the length of the cable or use fibre instead?

As tslytsly said, the cable is too long
You can install a switch in the middle of the cable or on maximum 80 meter cable length.

That was the problem

This is Eth1 (gateway).

Also i will try to make the cable shorter, to keep less than 100 meters.

Thanks!!
