Step 4: Installing the LLDP and Port Bonding

Before you install and configure the Dell OVS agent install the following on the Nova compute node and network node:

• LLDP package.

NOTE: Use the LLDP package for dynamic discovery of server switch connectivity. If you are using static

switch server connectivity, see Configuring Static Switch Server Connectivity.

• Port Bonding

Step 4.1: Installing the LLDP Package

To install LLDP on the Nova compute node. :

1. On the Nova compute node and network node, login as root.

2. Install the lldpd package using the apt-get install lldpd command.

3. Start the lldpd package using the service lldpd start command.

4. Install lldpad ( lldptool) using the apt-get install lldpad command.

5. Verify the successful installation of LLDP package on the Nova compute node and network node using the lldpctl

command to detect connected lldp neighbors.

Step 4.2: Install and Configure Port Bonding

When you connect to a Nova compute node and network node to the fabric that the Active Fabric Manager (AFM)

manages, you can connect to the Ethernet ports to the two leaf (or access) switches in the AFM supported topologies.

These two connections provide redundancy.

When you have two connections from a Nova compute node and network node to the switches, create a Ubuntu

Bonding port so that the compute node can use the redundancy from these two ports. For information about port

bonding, see https://help.ubuntu.com/community/UbuntuBonding?action=show&redirect=LinkAggregation.

To install and configure port bonding:

1. On the Nova compute node, install port bonding using the following command:

sudo apt-get install ifenslave-2.6

2. Verify that bonding module is in the kernel system is in the /etc/modules configuration file using the following

command.

sudo vi /etc/modules

The bonding module file should look like the following:

# /etc/modules: kernel modules to load at boot time.

# This file contains the names of kernel modules that should be loaded

# at boot time, one per line. Lines beginning with "#" are ignored.
