DHCP SNOOPING VERIFY MAC-ADDRESS
ip dhcp snooping verify mac-address
Overview Use this command to verify that the source MAC address and client hardware
address 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. 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
