Step 2: Up and Running
Now that the QFX5700 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 QFX5700 using the CLI.
Plug and Play
The QFX5700 switch ships with factory-default settings that enable plug-and-play operation. These settings load as soon as you power on the QFX5700 switch.
Customize the Basic Configuration
You can easily customize the factory-default configuration using CLI commands. Initially, you’ll need to make changes through the console port. After you configure the management port, you can access the device using SSH to make additional configuration changes. You can revert to the factory-default configuration whenever you want.
Have the following information ready before you begin to configure custom settings for the switch:
Hostname
Root authentication password
Management port IP address
Default gateway IP address
(Optional) SNMP read community, location, and contact information
Verify that your laptop or desktop PC has these default serial port settings:
Baud Rate—9600
Flow Control—None
Data—8
Parity—None
Stop Bits—1
DCD State—Disregard
Connect the console port on the QFX5700 to a laptop or desktop PC using an RJ-45 cable and RJ-45 to DB-9 adapter (not provided).
Note:If your laptop or desktop doesn't have a serial port, use a serial-to-USB adapter (not provided).
At the Junos OS Evolved 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.
login: root
Start the CLI.
root@% cli
Enter configuration mode.
root> configure
Add a password for the root administration user account.
[edit] 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 (“ ”).
[edit] root@# set system host-name host-name
Configure the IP address and prefix length for the management port on the switch.
Note:Although the CLI permits you to configure two management Ethernet interfaces within the same subnet, only one interface is usable and supported at any point of time.
[edit] root@# set interfaces re0:mgmt-0 unit 0 family inet address address/prefix-length
Create a routing instance.
[edit] root@# edit routing-instances mgmt_junos root@# set routing-instances mgmt_junos routing-options static route 0.0.0.0/0 next-hop 10.102.70.254
Configure the static routes to remote prefixes.
[edit] root@# set routing-options static route remote-prefix next-hop destination-ip
Enable the management instance.
[edit] root@# set system management-instance
Enable Telnet service if needed.
[edit] root@# set system services telnet
Note:When Telnet is enabled, you can’t log in to the QFX5700 through Telnet using root credentials. Root login is allowed only for SSH access.
Enable SSH service.
[edit] root@# set system services ssh
To allow users to log in to the switch as root through SSH, include the root-login statement.
[edit system services ssh] root@# root-login (allow | deny | deny-password)
Note:By default, users are not allowed to log in to the switch as root through SSH.
Commit the configuration. Your changes become the active configuration for the switch.
[edit] root@# commit
