Installing a Network Module in a QFX3100 Director Device

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

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:

   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-eth2
                
   

   HWADDR=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 ~]#
   

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

Installing a Network Module in a Director Device

• Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

• Ensure the Director device is configured for the new network module and powered down. See Removing a Power Supply from a QFX3100 Director Device (includes video).

• ESD grounding strap

1. Attach the ESD grounding strap to your bare wrist, and connect the strap to a site ESD point.
2. Taking care not to touch network module components, pins, leads, or solder connections, remove the network module from its bag.
3. Ensure that the network module is properly aligned with the network module slot. The network module faceplate should be aligned so the ports are numbered 0 through 3 from left to right.
4. Insert the network module into the network module slot, and gently push the module all the way into the slot until the module is seated flush in the network module slot.
   Caution

   Do not use too much force to seat the network module flush into the network module slot. If backpressure is preventing the network module from seating flush in the network module slot, remove the network module from the slot and retry the procedure, taking care to ensure that the network module is properly aligned with the network module slot.

5. Tighten both screws on the network module, using your fingers.
6. Power on the QFX3100 Director device. See Powering On a QFX3100 Director Device.

After system bootup, CentOS rescans the network module for MAC addresses and includes the new interfaces in the aggregated Ethernet (AE) bundle.
