4.11.16.2 Static Configuration
Add a static address to the source-guard binding table. 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.
Command Usage
• 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, of which static entries include a manually
configured lease time.
• 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.
