Before you Power Off the Director Device
date_range
05-Feb-16
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.
- 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:
content_copy zoom_out_map[root@qfabric ~]# ll /etc/sysconfig/network-scripts/ifcfg-eth1 -rw-r--r-- 1 root root 219 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth0 -rw-r--r-- 1 root root 153 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth1 -rw-r--r-- 1 root root 134 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth2 -rw-r--r-- 1 root root 135 Jun 17 07:15 /etc/sysconfig/network-scripts/ifcfg-eth3 -rw-r--r-- 1 root root 135 Jun 17 07:15 /etc/sysconfig/network-scripts/ifcfg-eth4 -rw-r--r-- 1 root root 135 Jun 17 07:15 /etc/sysconfig/network-scripts/ifcfg-eth5 -rw-r--r-- 1 root root 134 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth6 -rw-r--r-- 1 root root 121 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth7 -rw-r--r-- 1 root root 121 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth8 -rw-r--r-- 1 root root 121 Jun 17 07:14 /etc/sysconfig/network-scripts/ifcfg-eth9 [root@dg1 ~]# [root@dg1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2HWADDR=00:18:7D:31:19:C2 << Delete the entire line.DEVICE=eth2 USERCTL=no SLAVE=yes MASTER=bond0 ONBOOT=yes BOOTPROTO=static PEERDNS=no NOZEROCONF=yes MTU=9000 [root@qfabric ~]#
- Save the file and repeat the process with the remaining 3 files for the Director device.
- Locate and delete the following file:
[root@qfabric ~]# rm /etc/udev/rules.d/61-persistent-net.rules - Power off the QFX3100. See Powering Off a QFX3100 Director Device
