server on the network, the TFTP server must be identified. If configuring the
switch to use a DNS server to resolve hostnames into IP addresses, it is
possible to 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.
How Is Basic Network Information Configured?
A console-port connection is required to perform the initial switch
configuration. When booting the switch for the first time, if there is no
startup configuration file, the Dell Easy Setup Wizard starts. The Dell Easy
Setup Wizard is a CLI-based tool to help the administrator perform the
initial switch configuration. If no response to the Dell Easy Setup Wizard
prompt is received within 60 seconds, the console> prompt appears, and
the switch enters User Configuration mode.
For more information about performing the initial switch configuration by
using the wizard, see the Getting Started Guide at www.dell.com/support.
If the wizard is not used to supply the initial configuration information, the
administrator can manually enable the DHCP client on the switch to obtain
network information from a DHCP server via the in-band ports or the out-of-
band port. Alternatively, the network configuration can be statically
configured.
After configuring the switch with an IP address and creating a user account,
continue to use the console connection to configure basic network
information, or log on to the switch by using a Telnet client or a web browser.
It is possible at this point to change the IP address information and configure
additional network information from the remote system.
What Is Out-of-Band Management and In-Band Management?
The Dell EMC Networking N3000, N3100-ON, and N4000 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 switch, for example Telnet, SSH, DHCP
client, and TFTP. If using the out-of-band management port, it is strongly
