If the binding mode is not specified in this command, the entry is bound
◆
to the ACL table by default.
Table entries include a MAC address, IP address, lease time, entry type
◆
(Static-IP-SG-Binding, Dynamic-DHCP-Binding), VLAN identifier, and
port identifier.
All static entries are configured with an infinite lease time, which is
◆
indicated with a value of zero by the
(page 931).
When source guard is enabled, traffic is filtered based upon dynamic
◆
entries learned via DHCP snooping, or static addresses configured in
the source guard binding table with this command.
Static bindings are processed as follows:
◆
If there is no entry with same VLAN ID and MAC address, a new
■
entry is added to binding table using the type of static IP source
guard binding.
If there is an entry with 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 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.

This example configures a static source-guard binding on port 5. Since the
binding mode is not specified, the entry is bound to the ACL table by
default.
