5.2 Example for IP Source Guard
5.2.1 Network Requirements
As shown below, the legal host connects to the switch via port 1/0/1 and belongs to the
default VLAN 1. It is required that only the legal host can access the network via port 1/0/1,
and other unknown hosts will be blocked when trying to access the network via ports
1/0/1-3.

5.2.2 Configuration Scheme
To implement this requirement, you can use IP-MAC Binding and IP Source Guard to filter
out the packets received from the unknown hosts. The overview of configuration on the
switch is as follows:
1) Bind the MAC address, IP address, connected port number and VLAN ID of the legal
host with IP-MAC Binding.
2) Enable IP Source Guard on ports 1/0/1-3.
Demonstrated with T1500-28PCT, the following sections provide configuration procedure
in two ways: using the GUI and using the CLI.
