The dhcp packet-rule command configures whitelist rules to filter DHCP packets.
The undo dhcp packet-rule command deletes configured whitelist rules.
By default, no whitelist rule is configured.
dhcp packet-rule ruleid { source-ip source-ip-address { source-ip-mask | source-ip-mask-length } | destination-ip destination-ip-address { destination-ip-mask-length | destination-ip-mask } } * [ source-port { bootpc | bootps } ] [ destination-port { bootpc | bootps } ]
undo dhcp packet-rule ruleid [ { source-ip source-ip-address { source-ip-mask | source-ip-mask-length } | destination-ip destination-ip-address { destination-ip-mask-length | destination-ip-mask } } * [ source-port { bootpc | bootps } ] [ destination-port { bootpc | bootps } ] ]
