Configuring Static Binding for IP Source Guard
Use the 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.
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.
• 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.
Command Attributes
• Static Binding Table Counts – The total number of static entries in the table.
• Current Static Binding Table – The list of current static entries in the table.
• Port – The port to which a static entry is bound. (Range: 1-28/52)
• VLAN ID – ID of a configured VLAN (Range: 1-4094)
