ARP or broadcast IP packet is detected.
The default value is Disabled.
When both ARP and IP inspections are enabled, all IP packets are checked. The
legal IP packets are forwarded, while the illegal IP packets are dropped. When IP
Inspection is enabled, and ARP Inspection is disabled, all non-IP packets (Ex. L2
packets, or ARP) are forwarded by default.
The default value is Disabled.
Use the drop-down menu to select the protocol types, IPv4, IPv6 or All.
Use the drop-down menu to enable or disable this feature. Allow zero IP configures
the state which allows ARP packets with 0.0.0.0 source IP to bypass.
By default, the DHCP packet with broadcast DA will be flooded. When set to disable,
the broadcast DHCP packet received by the specified port will not be forwarded in
strict mode. This setting is effective when DHCP snooping is enabled, in the case
when a DHCP packet which has been trapped by the CPU needs to be forwarded by
the software. This setting controls the forwarding behavior in this situation.
Here is displayed the number of blocked entries on the port. The default value is 500.
