DHCP Snooping
DHCP Snooping expands network security by providing firewall security between untrusted interfaces
and DHCP servers. By enabling DHCP Snooping network administrators can differentiate between
trusted interfaces connected to end-users or DHCP Servers and untrusted interfaces located beyond the
network firewall.
For more information, see "Configuring DHCP Snooping" on page 269.
Additional CLI Documentation
The CLI Reference Guide, which is available on the Documentation CD, provides information about
the CLI commands used to configure the device. The document provides information including the CLI
description, syntax, default values, guidelines, and examples.
