Updating Network Settings After a NIC Replacement

 

If you replace your integrated system board or stand-alone (Network Interface Cards) NICs, you must update your JSA network settings to ensure that your hardware remains operational.

The network settings file contains one pair of lines for each NIC that is installed and one pair of lines for each NIC that was removed. You must remove the lines for the NIC that you removed and then rename the NIC that you installed.

Note

In previous releases of JSA, interfaces were named in the following format: eth0, eth1, eth4, and so on. JSA 7.3.0 interface naming includes a greater range of possible interface names. For example, ens192, enp2s0, and so on.

Your network settings file might resemble the following example, where NAME="<old_name>" is the NIC that was replaced and NAME="<new_name>" is the NIC that was installed.

  1. Use SSH to log in to the JSA product as the root user.

    The user name is root.

  2. Type the following command:

    cd /etc/udev/rules.d/

  3. To edit the network settings file, type the following command:

    vi 70-persistent-net.rules

  4. Remove the pair of lines for the NIC that was replaced: NAME=”<old_name>”.
  5. Rename the Name=<name> values for the newly installed NIC.
  6. Save and close the file.
  7. Type the following command: reboot.
