I have an SF-300-24 port switch and am having an issue.
When a device says "Who has 192.168.0.1" (which is the default gateway) two devices are replying in the affirmative, and therefor the MAC address table is getting screwed up.
I know the correct MAC address of 192.168.0.1 is 00:1b:21:95:02:b0, so how do I tell the router to disgard any packets that say otherwise? I tried to figure out DHCP snooping and IP source guard, and ARP Inspection, but I am not getting anywhere and keep losing connectivity to the switch.
Seems that this should be simple, any help is much appreciated! Obviously a device on the network is misconfigured, unfortunately it is a large wireless network and the misconfigured device is 30 miles away on the top of a mountain. I am hoping to bandaid it locally and then eventually go out and fix the offending equipment.
