Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than

requiring an administrator to manage the task. This means that a new computer can be added to a network without the

hassle of manually assigning it a unique IP address.

DHCP Relay

DHCP Relay is used to forward and to transfer DHCP messages between the clients and the server when they are not on

the same subnet domain.

The DHCP option 82 enables a DHCP relay agent to insert specific information into a DHCP request packets when

forwarding client DHCP packets to a DHCP server and remove the specific information from a DHCP reply packets when

forwarding server DHCP packets to a DHCP client. The DHCP server can use this information to implement IP address

or other assignment policies. Specifically the option works by setting two sub-options: Circuit ID (option 1) and Remote

ID (option2). The Circuit ID sub-option is supposed to include information specific to which circuit the request came in on.

The Remote ID sub-option was designed to carry information relating to the remote host end of the circuit.

The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The

parameter of "vlan_id" is the first two bytes represent the VLAN ID. The parameter of "module_id" is the third byte for the

module ID (in standalone switch it always equal 0, in stackable switch it means switch ID). The parameter of "port_no" is

the fourth byte and it means the port number.

The Remote ID is 6 bytes in length, and the value is equal the DHCP relay agents MAC address.

DHCP Snooping

DHCP Snooping is used to block intruder on the untrusted ports of the switch device when it tries to intervene by injecting

a bogus DHCP reply packet to a legitimate conversation between the DHCP client and server.

DNS

DNS is an acronym for

omain

ame

ystem. It stores and associates many types of information with domain names.

Most importantly, DNS translates human-friendly domain names and computer hostnames into computer-friendly IP

addresses. For example, the domain name www.example.com might translate to 192.168.0.1.

DoS

DoS is an acronym for

enial of

ervice. In a denial-of-service (DoS) attack, an attacker attempts to prevent legitimate

users from accessing information or services. By targeting at network sites or network connection, an attacker may be

able to prevent network users from accessing email, web sites, online accounts (banking, etc.), or other services that rely

on the affected computer.

Dotted Decimal Notation

Dotted Decimal Notation refers to a method of writing IP addresses using decimal numbers and dots as separators

between octets.
