Use the Security > IP Source Guard > Static Configuration page to bind a
static address to a port. Table entries include a MAC address, IP address,
lease time, entry type (Static, Dynamic), VLAN identifier, and port
identifier. All static entries are configured with an infinite lease time, which
is indicated with a value of zero in the table.

Static addresses entered in the source guard binding table are
◆
automatically configured with an infinite lease time. Dynamic entries
learned via DHCP snooping are configured by the DHCP server itself.
Static bindings are processed as follows:
◆
If there is no entry with the same VLAN ID and MAC address, a new
■
entry is added to the binding table using the type "static IP source
guard binding."
If there is an entry with the same VLAN ID and MAC address, and
■
the type of entry is static IP source guard binding, then the new
entry will replace the old one.
If there is an entry with the same VLAN ID and MAC address, and
■
the type of the entry is dynamic DHCP snooping binding, then the
new entry will replace the old one and the entry type will be
changed to static IP source guard binding.
Only unicast addresses are accepted for static bindings.
