DELL N3000 User Manual

Setting Basic Network Information

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 

server on the network, you must identify the TFTP server. If you configure 

the switch to use a DNS server to resolve hostnames into IP addresses, you 

can enter the hostname of the TFTP server instead of the IP address. It is 

often easier to remember a hostname than an IP address, and if the IP address 

is dynamically assigned, it might change from time-to-time.

You must use a console-port connection to perform the initial switch 

configuration. When you boot the switch for the first time and the 

configuration file is empty, the Dell Easy Setup Wizard starts. The Dell Easy 

Setup Wizard is a CLI-based tool to help you perform the initial switch 

configuration. If you do not respond to the Dell Easy Setup Wizard prompt 

within 60 seconds, the console> prompt appears, and you enter User 

Configuration mode.
For more information about performing the initial switch configuration by 

using the wizard, see the 

Getting Started Guide at 

If you do not use the wizard to prompt you for the initial configuration 

information, you can enable the DHCP client on the switch to obtain 

network information from a DHCP server on your network, or you can 

statically assign the network information.
After you configure the switch with an IP address and create a user account, 

you can continue to use the console connection to configure basic network 

information, or you can log on to the switch by using a Telnet client or a web 

browser. You can change the IP address information and configure additional 

network information from the remote system.

The Dell Networking 3000 and 4000 series switches have an external port 

intended solely for management of the switch. This port is the out-of-band 

(OOB) management port. Traffic received on the OOB port is never switched 

or routed to any in-band port and is not rate limited. Likewise, traffic received 

on any in-band port is never forwarded or routed over the OOB port. The only 

applications available on the OOB port are protocols required to manage the
