MAC Block List

This window is used to view unauthorized devices that have been blocked by IP-MAC binding restrictions.
To view this window, click Security > IP-MAC-Port Binding (IMPB) > MAC Block List as shown below:
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 pull-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.
