Built-In Ethernet Interface Address; Management Access - Juniper J4350 Getting Started Manual

If you use the J-Web Set Up Quick Configuration page, you can either set a
loopback address of your choice or have the loopback address automatically set to
127.0.0.1
Built–In Ethernet Interface Address
The built-in Gigabit Ethernet interfaces,
of the Services Router, are the interfaces through which you perform initial router
setup. The examples in this guide use the
interface, but you can use any built-in Ethernet port for management. After the
initial configuration is complete, you can attach the built-in Ethernet port that
you are using for management purposes to the management network.
Before initial configuration, when the factory default configuration is active,
the Services Router attempts to perform autoinstallation by obtaining a router
configuration through all its connected interfaces, including

After you perform the initial configuration and commit it by clicking Apply or OK
on the Set Up page, the configured router can no longer act as a DHCP server.
Therefore, in order to continue using it as a management interface you should
configure the IP address of the interface as part of the initial configuration.

Management Access

Telnet allows you to connect to the Services Router and access the CLI to
execute commands from a remote system. Telnet connections are not
encrypted and therefore can be intercepted.
