Recently started experiencing a weird issue with my Powerconnect 2848. Four switchports just stopped working.
When a cable is plugged in, the external LEDs appear to function normally. The MAC address table is appropriately updated if I move the cable between the four ports in question.
The web interface and 'show tech-support' seem to indicate that everything is running fine. When I reset the port counters, I can see activity for multicast and broadcast, both in and out, but none for unicast.
They're all in VLAN1, there is no port security set up. They're all force-authorized. No mirroring or port aggregation is set up. No config changes were made before this issue occurred.
I initially suspected a hardware error, but everything about the ports appear to be normal except for my inability to reach the connected host.
Anyone have any thoughts/ideas?
Thanks.
