IP Source Guard
FIGURE 232 Setting the Filter Type for IP Source Guard
Configuring Static Bindings for IP Source Guard
Use the Security > 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.
CLI References
• “ip source-guard binding” on page 221
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.
• Only unicast addresses are accepted for static bindings.
Parameters
These parameters are displayed:
Add
• Port – The port to which a static entry is bound.
• VLAN – ID of a configured VLAN (Range: 1-4093)
