An IP address is a 32-bit address allocated to a network interface on a
device that is attached to the Internet. This document describes:
Introduction to IP addresses
IP address configuration
Address Resolution Protocol (ARP) is used to resolve an IP address into a
data link layer address. This document describes:
ARP Overview
Configuring ARP
Configuring Gratuitous ARP
Proxy ARP and Local Proxy ARP configuration
If a host sends an ARP request for the MAC address of another host that
actually resides on another network , the device in between must be able
to respond to the request with the MAC address of the receiving interface
to allow Layer 3 communication between the two hosts. This is achieved
by proxy ARP. This document describes:
Proxy ARP Overview
Configuring Proxy ARP
Currently, ARP attacks and viruses are threatening LAN security. The
device can provide multiple features to detect and prevent such attacks.
This document describes:
Configuring ARP Source Suppression
Configuring ARP Defense Against IP Packet Attacks
Configuring ARP Active Acknowledgement
Configuring Source MAC Address Based ARP Attack Detection
Configuring ARP Packet Source MAC Address Consistency Check
Configuring ARP Packet Rate Limit
Configuring ARP Detection
DHCP is built on a client-server model, in which the client sends a
configuration request and then the server returns a reply to send
configuration parameters such as an IP address to the client. This
document describes:
Introduction to DHCP
DHCP Address Allocation
DHCP Message Format
DHCP Options
Protocols and Standards
Via a relay agent, DHCP clients communicate with a DHCP server on
another subnet to obtain configuration parameters. Thus, DHCP clients on
different subnets can contact the same DHCP server for ease of
centralized management and cost reduction. This document describes:
Introduction to DHCP Relay Agent
Configuring the DHCP Relay Agent
With the DHCP client enabled on an interface, the interface will use DHCP
to obtain configuration parameters such as an IP address from the DHCP
server. This document describes:
