I have equipment that never replies to PING. However the story sounds like someone made their own cables or if they used punchdowns got the pairs wrong.
The MAC table is good information, PING is not.
So given the light story, I'll wait for more.
I'm new in forum. I hope i can get some help here, and as i can see I can really start to help in some topics
So, here's my question.
I have a simple switch of 24 ports from ZTE and I have another equipment contected to it in one port.
The port is UP, but i can't ping the equipment. After 1minute (sometimes more, sometimes less) when port learns the other equipment's MAC ADDRESS it goes down.
I already tested. The port is up while i'm checking MAC table and there's no mac in port. When finally port learns the MAC i will check port state again and it is down. Some seconds later port is UP again and everything starts again.
Anyone have a idea what's can be the problem?
i already check negotion parameters and mac learning. It's everyting OK.
