config filter dhcp_server
22-3
Description
This command is used to configure filters on a DHCP server.
You can use DHCP Filtering as a security measure against unauthorized DHCP servers. A known
attack can occur when an unauthorized DHCP server responds to a client that is requesting an IP
address. The unauthorized server can configure the gateway for the client to be equal to the IP
address of the server. At that point, the client sends all of its IP traffic destined to other networks to
