Before you Power Off the Director Device

If you power off the QFX3100 Director device before configuring the new interfaces, the new interfaces will stay down or be removed from the control plane when the Director device is brought back up. If you are removing network module 1, you need to edit:

  • ifcfg-eth2

  • ifcfg-eth3

  • ifcfg-eth4

  • ifcfg-eth5

If you are removing network module 2, you need to edit:

  • ifcfg-eth6

  • ifcfg-eth7

  • ifcfg-eth8

  • ifcfg-eth9

Use the following procedure to edit the four ifcfg-ethn files.

  1. From root, use the vi editor to delete the HWADDR= line in each of the four files.

    For example, to configure ifcfg-eth1 for Director device 1:

  2. Save the file and repeat the process with the remaining 3 files for the Director device.
  3. Locate and delete the following file:

    [root@qfabric ~]# rm /etc/udev/rules.d/61-persistent-net.rules

  4. Power off the QFX3100. See Powering Off a QFX3100 Director Device
