What You Need To Know
Management IP Address
When you first connect a management PC or laptop to a built-in Ethernet port on a
Services Router, the router acts as a DHCP client and attempts to perform an
autoinstallation. If it does not find a DHCP server, the router assigns 192.168.1.1/24
as the IP address for port 0. (If you are connected to port 1, 192.168.2.1/24 is
assigned as the IP address. On the J2320, J2350, J4350 and J6350 routers, port 2
and port 3 are assigned 192.168.3.1/24 and 192.168.4.1/24, respectively.)
Because this address is not part of any explicit configuration, it is removed when
you change the configuration in any way. You must configure an IP address for this
LAN port when you commit your initial configuration. (See “Step 4. Configuring Basic
Settings with J-Web Quick Configuration” on page 11 or “Step 4. Configuring Basic
Settings with the CLI” on page 14.)
J-Web Access
The Web interface to the router—called the J-Web interface—is enabled by default.
To configure the router with the Web interface, you attach a PC or laptop to a built-in
Ethernet port. The examples in this document use the first built-in Ethernet port:
■
On J2300 routers, the first built-in Ethernet port is Fast Ethernet PORT 0 (internally
named fe-0/0/0).
■ On J2320, J2350, J4350 and J6350 routers, the first built-in Ethernet port is
Gigabit Ethernet port 0/0 (internally named ge-0/0/0).
See “Step 1. Connecting, Logging In, and Starting the J-Web Interface” on page 9.
CLI Console Access
Services Routers are shipped with a console cable and adapter. To configure a Services
Router through the console port with the JUNOS command-line interface (CLI), you
use a terminal emulation program such as Microsoft Windows HyperTermimal. (See
“Step 1. Connecting, Logging In, and Starting the CLI” on page 13.)
Required Licenses
To use the following features on a Services Router, you must purchase a license. (See
“Step 3. Adding Licenses with the CLI” on page 14 or “Step 4. Configuring Basic
Settings with J-Web Quick Configuration” on page 11.)
■ Advanced Border Gateway Protocol (BGP) support for route reflectors
■ Data link switching (DLSw)
■ J-Flow traffic analysis
