When the packet is found by the entry, the MAC address will be set to dynamic state. If the
packet is not found by the entry, the MAC address will be set to block. Other packets will be
bypassed.
Zero IP
Use the pull-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.
DHCP Packet 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. This setting is
effective when DHCP snooping is enabled, under the case that DHCP packets which have
been trapped by the CPU need to be forwarded by the software. This setting controls the
forwarding behavior in this situation.
Mode
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 entries and acl mode
entries will be effective. If the system is in the ACL mode, only the ACL mode entries will be
active.
ACL – Choosing this entry will allow only packets from the source IP-MAC binding entry
created here. All other packets with a different IP address will be discarded by the Switch. This
mode can only be used if the ACL Mode has been enabled in the IMP Global Settings
window as seen previously.
Stop Learning
Threshold
Specifies the maximum number of IP-MAC-Port Binding entries that can be learned. The range
