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.
Allow Zero IP
Use the drop-down menu to enable or disable this feature. Zero IP configures the state which
allows ARP packets with 0.0.0.0 source IP to bypass.
FDP
By default, the DHCP packet with broadcast DA will be flooded. When set to Disabled, the
broadcast DHCP packet received by the specified port will not be forwarded.
Mode
The user may set the mode for this IP-MAC-port binding settings by choosing ARP or ACL.
When configuring the mode of the port to ACL, the Switch will create an ACL access entry
corresponding to the entries of this port. If the port changes to ARP, all the ACL entries will be
deleted automatically. The default mode is ARP.
SLT (0-500)
Enter a Stop-learning Threshold value between 0 and 500. The default SLT for each port is
500.
Max Entry (1-50)
Specifies the maximum number of IP-MAC-port binding entries between 1 and 50. The default
is 5. Alternatively, tick the No Limit check box.
