•
Table entries include a MAC address, IP address, lease time, entry type (Static-IP-SG-Binding,

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
