Configuring IP Source Guard
Beginning in Privileged EXEC mode, use the following commands to
configure IPSG settings on the switch.
Command Purpose
configure Enter global configuration mode.
interface interface Enter interface configuration mode for the specified port
or LAG. The interface variable includes the interface type
and number, for example gigabitethernet 1/0/3. For a
LAG, the interface type is port-channel.
You can also specify a range of ports with the interface
range command, for example, interface range
gigabitethernet 1/0/8-12 configures interfaces 8, 9, 10, 11,
and 12.
ip verify source [port-
security]
Enable IPSG on the port or LAG to prevent packet
forwarding if the source IP address in the packet is not in
the DHCP snooping binding database. Use the option
port-security keyword to also prevent packet forwarding if
the sender MAC address is not in forwarding database
table or the DHCP snooping binding database. \
NOTE: To enforce filtering based on the source MAC
address, port security must also be enabled on the interface
by using the port security command in Interface
Configuration mode.
