Establishing Basic Connectivity
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
when you click
Apply
or
OK
to commit the configuration.
Built–In Ethernet Interface Address
The built-in Gigabit Ethernet interfaces,
ge-0/0/0
through
ge-0/0/3
, on the front panel
of the Services Router, are the interfaces through which you perform initial router
setup. The examples in this guide use the
ge-0/0/0
interface as the management
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
ge-0/0/0
. The Services
Router acts as a DHCP client out the built-in Ethernet interfaces.
If the Services Router does not find a DHCP server within a few
seconds, it sets the address of
ge-0/0/0
to
192.168.1.1/24
and becomes
a DHCP server out the
ge-0/0/0
interface.
NOTE:
If the
ge-0/0/1
interface is being used, it is set to
192.168.2.1/24
.
With the router temporarily acting as a DHCP server, you can manually
configure it with the J-Web interface. Any DHCP client host, for example,
a PC or laptop computer, directly connected to
ge-0/0/0
receives an
address on the
192.168.1.1/24
network.
NOTE:
The DHCP functionality for initial setup is different from the configurable
DHCP server functionality of the Services Router during operation. To configure the
Services Router as a DHCP server, see the
J-series Services Router Administration
Guide
.
Once you connect your laptop or PC to
ge-0/0/0
, you can use a Web browser to
visit the address
192.168.1.1/24
, access the J-Web Set Up Quick Configuration
page, and complete the initial configuration of the router.
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.
