Question : Problem: Losing network connectivity on Cisco VG224
|
|
I periodically lose network connectivity, (ex.can not ping, and no network devices can communicate) with my VG224. Does anyone have any ideas as to why this might be happening. Here are my version, and configuration between the VG224 fastethernet interface and the connected switches fastethernet interface.

Answer : Problem: Losing network connectivity on Cisco VG224

Input and run errors are indicative of cabling and/or possible duplex mismatch settings on each device. Make sure each device has the same speed and duplex settings. Replace cable with new cable and clear counters and see if you continue to increment errors.
