Creating a Network Aggregated Link with Ops Center (12R2)

Contributed by Juergen Fleischer and Mahesh Sharma.

In this short blog we will use Ops Center to create Link Aggregation. This will allow us to combine multiple network connections in parallel to increase the throughput and provide redundancy.

If you recall from the ""Ops Center 12.2: Creating a CDOM - Detaching Unused PCIe Buses - Adding PCIe Buses", we created the CDOM with just one network connection (net0, ixbge2), this was from pci_0 which is the onboard bus. Pci_0 also had device ixgbe3 attached which we did not configure during provisioning.

In the “"Ops Center 12.2: Creating a CDOM - Detaching Unused PCIe Buses - Adding PCIe Buses" blog we also attached another PCIe bus (pci_1) to the Control Domain, which gave us another two network devices (ixbge0 and ixbge2) as seen below.

So to summarize we have the following devices:

Link PCIe Bus Physical Device
net0 pci_0 (on board) ixgbe2
net1 pci_0 (on board) xgbe3
net4 pci_1 xgbe0
net5 pci_1 xgbe1

The idea here is that net1, net4 and net5 will be connected to our Production network on the CDOM. As mentioned above we would like to combine the Nets to provide some redundancy and better throughput.

So, let us create the aggregated link with Ops Center.

From: Navigation -> Assets , select the CDOM OS Asset as shown below:

From the tabs in the middle panel select "Networks" then "Link Aggregations". Click on green plus sign “Create Link Aggregations”

From the next screen, specify an aggregation name and move the nets from “Available Network Interfaces” to “Link Aggregation Members”, as shown below:

The next screen allows you to configure the Links:

The last step is to review the Summary and click Finish.

Let’s confirm these changes have taken place by command line and from the Ops Center BUI.

From the command line, log on to the Control Domain and run the following:

We can see we have an aggregated link called aggr0, which consisting of net 1, 4 and 5.

This can also be seen from the BUI.

Hope this helps!
