I'm trying to track down the logic for this, any help would be appreciated.
For reference, Computer A is attached to Switch A, Computer B is attached to Switch B. Both computers have the same IP address assigned, one obtained through DHCP, the other erroneously statically set.
Port-securtiy is triggered on switch A because the maximum mac-count on the port had been reached. The mac-address that triggered this even belongs to Computer B attached to Switch B.
How did a computer attached to Switch B trigger a port-security event on Switch A based on a duplicate IP address?
Closests answer I have so far is based on gratuitous ARP that windows uses to detect duplicate IP addresses, but that doesn't not explain to me how a frame with the source mac-address of Computer B originated from Computer A's port.
Thanks in advance,
