no
variant of this command to disable MAC address verification.

Usage
When MAC address verification is enabled, the switch treats DHCP packets with
source MAC address and client hardware address that do not match as DHCP
snooping violations: it drops them and applies any other violation action specified
by the
ip dhcp snooping violation
command. To bring the port back up again after
any issues have been resolved, use the
shutdown
command.
Example
To disable MAC address verification on the switch, use the commands:
awplus#
configure terminal
awplus(config)#
no ip dhcp snooping verify mac-address
