Disabling the MAC address check

DHCP snooping drops DHCP packets received on untrusted ports when the check address (chaddr) field in the DHCP header does not match the source MAC address of the packet (default behavior). To disable this checking, use the no form of this command.

switch(config)# dhcp-snooping verify mac

Showing the DHCP snooping verify MAC setting
