IP packets will be dropped.

ipv4 - Only IPv4 packets will be checked.
ipv6 - Specify that only IPv6 packets will be checked.
all - Specify that all packets will be checked.
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.
enable - Specify that the allow zero IP option will be enabled.
disable - Specify that the allow zero IP option will be disabled.
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
forwarded. This setting is effective when DHCP Snooping is enabled, in this case DHCP
packets trapped by the CPU must be forwarded by the software. This setting controls the
forwarding behavior in this situation.
enable - Specify that the forward DHCP packets option will be enabled.
disable - Specify that the forward DHCP packets option will be disabled.
stop_learning_threshold - (Optional) When the number of blocked entries exceeds the
threshold, the port will stop learning new addresses. Packets with a new address will be
dropped.
<int 0-500> - Enter the stop learning threshold value here. This value must be between 0 and
500.
