As a DHCP security feature, DHCP snooping can ensure DHCP clients to
obtain IP addresses from authorized DHCP servers and record IP-to-MAC
mappings of DHCP clients.This document describes:
DHCP Snooping Overview
Configuring DHCP Snooping Basic Functions
Configuring DHCP Snooping to Support Option 82
After you specify an interface of a device as a BOOTP client, the interface
can use BOOTP to get information (such as IP address) from the BOOTP
server. This document describes:
Introduction to BOOTP Client
Configuring an Interface to Dynamically Obtain an IP Address Through
BOOTP
Used in the TCP/IP application, Domain Name System (DNS) is a
distributed database which provides the translation between domain name
and the IP address. This document describes:
Configuring the DNS Client
Configuring the DNS Proxy
In some network environments, you need to adjust the IP parameters to
achieve best network performance. This document describes:
Enabling Reception and Forwarding of Directed Broadcasts to a
Directly Connected Network
Configuring TCP Attributes
Configuring ICMP to Send Error Packets
UDP Helper functions as a relay agent that converts UDP broadcast
packets into unicast packets and forwards them to a specified server. This
document describes:
UDP Helper overview
UDP Helper configuration
Internet protocol version 6 (IPv6), also called IP next generation (IPng),
was designed by the Internet Engineering Task Force (IETF) as the
successor to Internet protocol version 4 (IPv4). This document describes:
IPv6 overview
Basic IPv6 functions configuration
IPv6 NDP configuration
PMTU discovery configuration

A network node that supports both IPv4 and IPv6 is called a dual stack
node. A dual stack node configured with an IPv4 address and an IPv6
address can have both IPv4 and IPv6 packets transmitted. This document
describes:
Dual stack overview
Dual stack configuration
Based on packet sampling, Sampled Flow (sFlow) is a traffic monitoring
technology mainly used to collect and analyze traffic statistics. This
