match in DHCP packets received on untrusted ports.
Use the no variant of this command to disable MAC address verification.
Syntax ip dhcp snooping verify mac-address
no ip dhcp snooping verify mac-address
Default Enabled—source MAC addresses are verified by default.
Mode Global Configuration
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 on page 56.22 . To bring the port back up again after any issues have
been resolved, use the no shutdown command on page 12.14 .
Example To disable MAC address verification on the switch, use the commands:
