Before you begin connecting and configuring the switch, set the following parameter values on the console server or PC:

Baud Rate—9600
Flow Control—None
Data—8
Parity—None
Stop Bits—1
DCD State—Disregard

You must perform the initial configuration of a QFX10000 modular switch through the console port using the command-line interface (CLI) or through Zero Touch Provisioning (ZTP). On QFX10002 fixed-chassis models, in addition to using the CLI, you may also use ZTP. In order to provision the QFX10002 using ZTP, you must have access to a Dynamic Host Control Protocol (DHCP) server and a File Transfer Protocol (anonymous FTP), Hypertext Transfer Protocol (HTTP), or Trivial File Transfer Potocol (TFTP) server on which the software image and configuration files are stored. For more information about using ZTP for provisioning the device, see Zero Touch Provisioning Overview.

The following procedure sets up the QFX10000 using the command-line interface (CLI).

To connect and configure the switch from the console:

Connect the console port to a laptop or PC using an RJ-45 cable and RJ-45 to DB-9 adapter. The console (CON) port is located on the port panel of the switch.
Log in as root. There is no password. If the software booted before you connected 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 to the root administration user account.

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 default gateway.

root@# set routing-options static route default next-hop address

Configure the IP address and prefix length for the switch management interface.
```
[edit]
root@# set interfaces em0 unit 0 family inet address address/prefix-length
```
CAUTION:
Although the CLI permits you to configure two management Ethernet interfaces within the same subnet, only one interface is usable and supported.

Note:
The management ports, em0 (MGMT for RJ-45 connections) and em1 (also labeled MGMT for fiber connections), are found on the port panel of the QFX10002 and on each of the Routing and Control Boards of the QFX10008 and QFX10016.
Note:
We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:
RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)

RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)

RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.
(Optional) Configure the static routes to remote prefixes with access to the management port.
```
[edit]
root@# set routing-options static route remote-prefix next-hop destination-ip retain no-readvertise
```
Enable Telnet service.
```
[edit]
root@# set system services telnet 
```
Note:
When Telnet is enabled, you cannot log in to a QFX10000 through Telnet using root credentials. Root login is allowed only for SSH access.
Commit the configuration to activate it on the switch.
```
[edit] 
root@# commit
