Step 2: Up and Running
Now that the EX4600 is powered on, let’s do some initial configuration to get it up and running on the network. It’s simple to provision and manage the EX4600 using the CLI.
Plug and Play
The EX4600 switch ships with factory-default settings that enable plug-and-play operation. These settings load as soon as you power on the switch.
Customize the Basic Configuration
You can easily customize the factory-default configuration using CLI commands. You can revert to the factory-default configuration whenever you want.
Have the following information handy before you begin customizing switch settings:
Root authentication password
Management port IP address
Default gateway IP address
(Optional) SNMP read community, location, and contact information
- Verify that the serial port settings for your laptop or
desktop PC are set to the default:
- Connect the console (
CON) port on the switch’s management panel to a laptop or desktop PC using the RJ-45 cable and RJ-45 to DB-9 adapter (not provided).
If your laptop or desktop PC doesn't have a serial port, use a serial-to-USB adapter (not provided).
- At the Junos OS login prompt, type root to log in. You don't need to enter a password. If the software booted
before you connected the laptop or desktop to the console port, you
might need to press the Enter key for the prompt to appear.
- Start the CLI.
- Enter configuration mode.
- Add a password for the root administration user account.
root@# set system root-authentication plain-text-password
New password: password
Retype new password: password
- (Optional) Configure the name of the switch. If the name
includes spaces, enclose the name in quotation marks (“ ”).
root@# set system host-name host-name
- Configure the default gateway.
root@# set routing-options static route default next-hop address
- Configure the IP address and prefix length for the switch
root@# set interfaces em0 unit 0 family inet address address/prefix-length
Although the CLI lets you configure two management Ethernet interfaces within the same subnet, only one interface is usable and supported at any point in time.
The management ports, em0 (labeled
C0), and em1 (labeled
C1), are on the switch’s management panel.
- Configure the static routes to remote prefixes with access
to the management port.
root@# set routing-options static route remote-prefix next-hop destination-ipretain no-readvertise
- Enable Telnet service.
root@# set system services telnet
When Telnet is enabled, you cannot log in to the EX4600 through Telnet using root credentials. Root login is allowed only for SSH access.
- Commit the configuration. Your changes become the active
configuration for the switch.
