the entries for the ports. The port will check ARP packets and IP packets by IP-MAC-PORT
Binding entries. When the packet is found by the entry, the MAC address will be set to
dynamic. If the packet is not found by the entry, the MAC address will be set to block. Other
packets will be dropped. The default mode is strict if not specified.
This mode provides a looser way of control. If the user selects loose mode, ARP packets and
IP Broadcast packets will be sent to the CPU. The packets will still be forwarded by the
hardware until a specific source MAC address is blocked by the software. The port will check
ARP packets and IP Broadcast packets by IP-MAC-PORT Binding entries. When the packet is
found by the entry, the MAC address will be set to dynamic. If the packet is not found by the
entry, the MAC address will be set to block. Other packets will be bypassed.
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.
Specifies the maximum number of IP-MAC-Port Binding entries. By default, per port max entry
is 5. The Max entry threshold is 1-10.

Description
Enter the IP address to bind to the MAC address set below.
Enter the MAC address to bind to the IP Address set above.
The user may set the IP-MAC Binding Mode here by using the pull-down menu. The choices
are:
ARP – Choosing this selection will set a normal IP-Mac Binding entry for the IP address and
MAC address entered. If the system is in ARP mode, the arp mode will be effective.
Specify the switch ports for which to configure this IP-MAC binding entry (IP Address + MAC
Address). Click the All check box to configure this entry for all ports on the Switch.
