I have Xyxel P-660R ADSL modem connected to Cisco Switch Catalyst Express 500 series. At random interval of times the switch port turn orange from green. And the internet get down until i dont reset the switch manually.
I am unable to detect the problem.
The line speed is correct.
Have changed the cable.
(as stated on cisco site for common causes that can terminate the port and put on errdisable.)
Is there anything else i can do? where to look? What possible measures i can take to resolve the issue?
Please help.
