Configuration Examples

4.1 Example for DHCPv4 Filter

4.1.1 Network Requirements

As shown below, all the DHCPv4 clients get IP addresses from the legal DHCPv4 server,

and any other DHCPv4 server in the LAN is regarded as illegal. Now it is required that only

the legal DHCPv4 server is allowed to assign IP addresses to the clients.

4.1.2 Configuration Scheme

To meet the requirements, you can configure DHCPv4 Filter to filter the DHCPv4 packets

from the illegal DHCPv4 server.
The overview of configuration is as follows:
1) Enable DHCPv4 Filter globally and on all ports.
2) Create an entry for the legal DHCPv4 server.
Demonstrated with T2600G-28TS, the following sections provide configuration procedure

in two ways: using the GUI and using the CLI.
