Performing the Initial Software Configuration for the PTX3000

These procedures connect a PTX3000 to the network but do not enable it to forward traffic. For complete information about enabling the PTX3000 to forward traffic, including examples, see the Junos OS configuration guides.

You configure the PTX3000 by issuing Junos OS CLI commands, either on a console device attached to the CON port, or over a Telnet connection to a network connected to the management Ethernet port.

Note:

These procedures enable you to use the management Ethernet port. For the initial configuration, use a device attached to the CON port.

Preparing to Configure the PTX3000

Gather the following information before configuring the PTX3000:

  • Name the PTX3000 will use on the network

  • Domain name the PTX3000 will use

  • IP address and prefix length information for the Ethernet interface

  • IP address of a default router

  • IP address of a DNS server

  • Password for the root user

Entering Configuration Mode

  1. Verify that the network device is powered on.
  2. Log in as the root user. There is no password.
  3. Start the CLI.
  4. Enter configuration mode.

Configuring User Accounts and Passwords

For information about using an encrypted password or an SSH public key string (DSA or RSA), see Configuring the Root Password and user.

  1. Add a password to the root administration user account. Enter a cleartext password.
  2. Create a management console user account.
  3. Set the user account class to super-user.

Configuring System Attributes

  1. Configure the name of the PTX3000. If the name includes spaces, enclose the name in quotation marks (“ ”).
    Note:

    The DNS server does not use the hostname to resolve to the correct IP address. This hostname is used to display the name of the device in the CLI. For example, this hostname is displayed on the command-line prompt when the user is logged in to the CLI:

  2. Configure the IP address of the DNS server.
  3. Configure the domain name of the PTX3000.
  4. Configure the IP address and prefix length for the PTX3000 router’s management Ethernet interface.
  5. Configure the IP address of a backup router. The backup router allows the PTX3000 to install a route to the management network while the Routing Engine or RCB is booting and before the routing protocol process (rpd) is up and running. The backup router must be directly connected—that is, on the same subnet—through the management Ethernet interface.
  6. (Optional) Configure the static routes to remote subnets with access to the management port. Access to the management port is limited to the local subnet. To access the management port from a remote subnet, you must add a static route to that subnet within the routing table.
  7. Configure the Telnet service at the [edit system services] hierarchy level.

Committing the Configuration

  1. Display the configuration to verify that it is correct.
  2. Commit the configuration to activate it.
  3. Optionally, configure additional properties by adding the necessary configuration statements. Then commit the changes to activate them.
  4. When you have finished the configuration, exit configuration mode.
