Dynamic Host Configuration Protocol

Configuring the DHCP Server

This switch includes a Dynamic Host Configuration Protocol (DHCP) server that can

assign temporary IP addresses to any attached host req uesting service. It can also

provide other network settings such as the domain name, default gateway, Domain

Name Servers (DNS), Windows Internet Naming Service (WINS) name servers, or

information on the bootup file for the host device to download.

Addresses can be assigned to clients from a common address pool configured for a

specific IP interface on this switch, or fixed addresses can be assigned to hosts

based on the client identifier code or MAC address.

Command Usage

• First configure any excluded addresses, including the address for this switch.

• Then configure address pools for the network interfaces. You can co nfigure up to

8 network address pools. You can also manually bind an address to a specific

client if required. However, any fixed addresses must fall within the range of an

existing network address pool. You can configure up to 32 fixed host addresses

(i.e., entering one address per pool).

• If the DHCP server is running, you must disable it and then reenable it to implement

any configuration changes. This can be done on the DHCP, Server, General pag e.

Enabling the Server, Setting Excluded Addresses

Enable the DHCP Server and specify the IP addresses that it should not be

assigned to clients.

Command Attributes

•DHCP Server – Enables or disables the DHCP server on this switch.

(Default:Disabled)

•Excluded Addresses – Specifies IP addresses that the DHCP server s hould not

assign to DHCP clients. You can specify a single address or an address range.

•New (Excluded Addresses) – New entries for excluded addresse s can be specified

as a single address or an address range.

Note: Be sure you exclude the address for this switch and other key network devices.
