Step 7 (Optional): Configuring the eth1 Interface

 

You use the eth1 interface as the administrative interface for the Junos Space or FMPM node. When the Junos Space or FMPM node reboots after the basic configuration, configure the eth1 interface.

Note
  • From Junos Space Network Management Platform Release 14.1R1 onward, you can configure the eth1 Ethernet interface as an administrative interface.

  • The eth1 interface must be configured separately for each node in a multinode fabric.

  • If you configure the eth1 interface, SSH is disabled on the eth0 and the eth3 interfaces. You can then access the CLI of the Junos Space appliance only through the eth1 interface.

To configure the eth1 interface:

  1. On the Junos Space Settings Menu, type 6 to access the shell.

    You are prompted to enter your password.

  2. Type your password and press Enter.

    The shell prompt appears.

  3. At the shell prompt, type jmp_config and press Enter.

    You are prompted to enter the IP address of the eth1 interface.

  4. Type the IP address of the eth1 interface in dotted decimal notation and press Enter.

    The IP address can be in the same subnet as the virtual IP (VIP) address or in a different subnet. If the IP address is not in the same subnet as the VIP address, you are prompted to enter the subnet mask and then the default gateway for the eth1 interface.

  5. (Optional) Type the subnet mask for the eth1 interface in dotted decimal notation and press Enter.
  6. (Optional) Type the default gateway in dotted decimal notation and press Enter.

    The eth1 interface is configured.

  7. To verify that the eth1 address is configured, run the ifconfig eth1 command and check that the IP address displayed for eth1 is the same as the one that you configured.

    You can now access the Junos Space or FMPM node through the eth1 interface to perform administrative tasks.

To troubleshoot issues in configuring the eth1 interface, refer to the /var/log/changeEth1.log file.
