190 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?
Dell EMC Networking N-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. A
username and password is required to be able to log into the switch from a
remote host. For information about configuring users, see "Authentication,
Authorization, and Accounting" on page 253. If managing the switch by using
the console connection only, configuring an IP address and user is not
required. In this case, disabling the Telnet server using the no ip telnet
command is recommended.
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 a
hostname is entered without the domain name
information, the default domain name is automatically
appended to the hostname.
Host Name Mapping Allows statically mapping an IP address to a hostname.
NOTE: The configuration example in this chapter includes commands to create
an administrative user with read/write access.
