What would cause DHCP Snooping to report a MAC doesn't match it's client hardware address?
Source MAC address 48:A9:D2:20:5A:1B does not match client hardware address 00:03:78:C7:42:FC. This message appears when DHCP Snooping drops the source mac address doest not match the clinet Hardware address.

Hi Electrical,
May you be able to share the logs of the switch so that we can check what seems to be going on? What is the client with the incorrect MAC address?

Yes sorry, here are the logs you've requested. I'm starting to wonder if the backup blade is not ending it's nonstop forwarding state when the management blade recovers from being unreachable. My theory is that if the forwarding state persists for too long then the MAC table becomes stale and IPs start to not match their MACs due to DHCP.
The client device is a DirectTV H25 receiver with a wireless ethernet over coax adapter like this one.
