122 Setting Basic Network Information
Additionally, this chapter describes how to view host name-to-IP address 
mappings that have been dynamically learned by the system.
Why Is Basic Network Information Needed?
PowerConnect 7000 Series switches are layer 2/3 managed switches. To 
manage the switch remotely by using a web browser or Telnet client, the 
switch must have an IP address, subnet mask, and default gateway. You must 
also configure a username and password to be able to log into the switch from 
a remote host. For information about configuring users, see "Configuring 
Authentication, Authorization, and Accounting" on page 175. If you manage 
the switch only by using a console connection, configuring an IP address and 
user is not required.
Configuring the DNS information, default domain name, and host name 
mapping help the switch identify and locate other devices on the network and 
on the Internet. For example, to upgrade the switch software by using a TFTP 
Default Gateway Typically a router interface that is directly connected to 
the switch and is in the same subnet. The switch sends 
IP packets to the default gateway when it does not 
recognize the destination IP address in a packet.
DHCP Client Requests network information from a DHCP server on 
the network. 
Domain Name System 
(DNS) Server
Translates hostnames into IP addresses. The server 
maintains a domain name databases and their 
corresponding IP addresses.
Default Domain Name Identifies your network, such as dell.com. If you enter a 
hostname and do not include the domain name 
information, the default domain name is automatically 
appended to the hostname.
Host Name Mapping Allows you to statically map an IP address to a 
hostname. 
NOTE: The configuration example in this chapter includes commands to create 
an administrative user with read/write access.
