Description: The false packets(chaddr in DHCP packets is not same with source Mac-address in Ethernet frame) count.
What is hwChaddrNomatchSrcMacDhcpPktNum?
A running count of DHCP packets discarded because their CHADDR field didn't match the Ethernet frame's source MAC address on this interface/VLAN, indicating attempted client spoofing.
Examples
