Guard
Use the Security > IP Source Guard > Static Binding (Configure ACL Table and
Configure MAC Table) pages 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
Table entries include a MAC address, IP address, lease time, entry type (Static-IP-
SG-Binding, Dynamic-DHCP-Binding), VLAN identifier, and port identifier.
Static addresses entered in the source guard binding table are automatically
configured with an infinite lease time.
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.
An entry with same MAC address and a diferent VLAN ID cannot be added to
the binding table .
Static bindings are processed as follows:
A valid static IP source guard entry will be added to the binding table in
ACL mode if one of the following conditions is true:
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.
