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 static IP source guard binding table.
■ 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.
PARAMETERS
