Description
Select a port or range of ports to set for IP-MAC Binding.
Use the pull-down menu to Enable or Disable these ports for IP-MAC Binding.
Enabled (Strict) – This mode provides a stricter method of control. If the user selects this
mode, all packets will be sent to the CPU, thus all packets will not be forwarded by the
hardware until the S/W learns 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 Enabled (Strict) if not
specified.
Enabled (Loose) – 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.
