Dynamic Host Configuration Protocol (DHCP) Snooping is a security feature which filters untrusted DHCP messages, this security feature can protects the devices on the network from associating with an unauthorized DHCP server. When the Dynamic Host Configuration Protocol (DHCP) Snooping feature is enabled on a Cisco Switch , the Cisco Switch builds a table of MAC address, IP address lease time , binding type and interface information. In coming posts I will try to explain to how to enable and configure the Dynamic Host Configuration Protocol (DHCP) snooping security feature in a Cisco Switch.
