Port Flapping

Tue Jul 19, 2016 7:30 am

I'm running into an issue with more than one rb where ports are flapping or it will auto negotiate to 100Mbs & 1Gpbs within seconds.

See attached image. Running OS 6.35.2 will be upgrading firmware to 6.35.4 to see if it helps.

Hi,

How long is that cable of yours?

Which device?  What kind if environment?
I encountered such an issue in a rooftop installation and it was caused by a very strong local transmitter.
It has been solved by putting ferrite clamps over some cables (network, supply, etc),
But in your case the cause may be different.

The runs are about 140' or less.

On private towers, not sharing space with anyone else.

Now seeing other ports without anything plugged into them going to 10Mb connection rate and then shutting off.  :shock:
