allow_zeroip
- (Optional) Specify whether to allow ARP packets with a source IP address of
0.0.0.0. If the IP address 0.0.0.0 is not configured in the binding list and this setting is enabled,
ARP packets with the source IP address of 0.0.0.0 will be allowed; If the IP address 0.0.0.0 is
not configured in the binding list and this setting is disabled, ARP packets with the source IP
address of 0.0.0.0 will not be allowed. This option does not affect the IMPB ACL Mode.

forward_dhcppkt
- (Optional) By default, DHCP packets with a broadcast DA will be flooded.
When set to disabled, the broadcast DHCP packet received by the specified port will not be

packets trapped by the CPU must be forwarded by the software. This setting controls the
forwarding behavior in this situation.
