Configuration Guide Configuring Global IP-MAC Binding
IP Network is an external IP network.
Deployment
Manually configure the global IP-MAC binding. (Take three users as an example.)
Enable the IP-MAC binding function globally.
Configure the uplink port (Gi0/5 port in this example) of the device as the exclude port.

Basic Concepts
IPv6 Address Binding Mode
IPv6 address binding modes include Compatible, Loose, and Strict. The default mode is Strict. If IPv4-MAC binding is not
configured, the IPv6 address binding mode does not take effect, and all IPv4 and IPv6 packets are allowed to pass through. If
IPv4-MAC binding is configured, the IPv6 address binding mode takes effect, and the device forwards IPv4 and IPv6 packets
based on the forwarding rules described in the following table:
IPv4 Packet Forwarding Rule
IPv6 Packet Forwarding Rule
Packets matching the global IPv4-MAC
binding are forwarded.
Packets matching the global IPv6-MAC binding are forwarded.
(The binding is generated by other access security functions,
such as port security and IPv6 Source Guard.)
Packets matching the global IPv4-MAC
binding are forwarded.
If IPv6+MAC address binding is configured, packets matching
the IPv6-MAC binding are forwarded. (The binding is generated
by other access security functions, such as port security and
IPv6 Source Guard.)
If IPv6-MAC binding does not exist, all IPv6 packets are
forwarded.
Packets matching the global IPv4-MAC
binding are forwarded.
If the IPv6 packets contain a MAC address matching the MAC
address in the IPv4-MAC binding, the IPv6 packets are
forwarded.
Packets matching the global IPv6-MAC binding conditions are
forwarded. (The binding is generated by other access security
functions, such as port security and IPv6 Source Guard.)
