Broadcom NIC Teaming


With NIC teaming, the 2 options that we care about are Load Balancing and Fail Over. They both have
their own advantages.

With both scenarios, each adapter will be hidden from the outside world and all the traffic will go
through the “virtual” adapter which will have the static IP.

With Load balancing the network will be split between both NICs to keep the load to a minimum. This
will help with some over head associated with TCP/IP traffic; TOE will also save the CPU from
having to
deal with the overhead. This is preferable for all the camera traffic, since it is continuous traffic. If a NIC
fails in the scenario, all the traffic will just be pushed through the remaining adapters, so it is a
combination of LB + Fail Over.

With Fail over, you basically have 1 NIC working, and if it dies, the virtual adapter will push all the data
to the next one in line. This scenario does not help with network as a bottleneck.

Both teams do support TOE.

Download the Server Management

First you must download the Broadcom Advanced Server Program (BASP) from the Broadcom website.

Find the correct link by seeing what NIC you have; most of the Dells are using the 5708.

Choose the correct series, then on the next page, scroll down almost to the bottom where it says
Windows Management Applications. You will want to download the 32bit versio
n, which is the first one

Install Management Tools

You need to extract that zip file, and then go all the way through all those folders until you run the

Make sure that BASP is going to install. You can leave SNMP and CIM as not b
eing installed.

Finish out that installer and once you are done, you will be required to reboot. Once the server comes
back up, you will need to browse to C:
Program Files
BASP and run 2 executables:

After that, open up Broadcom Advanced Control Suite (through control panel, or through the Start
menu under Broadcom folder. It should now I have a new icon at the bottom below Device

Click on that icon, it will take you to the Teaming

section of the program.

Right click on Team, and select Create Team

It will then ask you for the Team name. It doesn’t really matter much, I called mine NVR Team.

Next it will ask you what type of team you want, you want to leave it defaulted to the t
op one, Smart
Load Balancing and Failover. That is the only way to have TOE enabled.

It will then ask you what adapters you want to add to the team, simply click on each one then click the
add button, they should both be on the bottom.

The next screen

will allow you to set up the team for failover if you would like. If you do not want fail
over, don’t configure a standby member.

The next screen will ask if you want to have Live Link enabled, which you do not. Live link will probe an
IP at a set int
erval, and if that link ever fails, it will then roll over to the standby NIC. This will require
you to have 3 static IPs and a constant ping every x seconds. I do not think it is necessary, or advisable.

The next screen will ask if you want to add a VLA
N which you do, so select Add VLAN and click Next.

Give your VLAN a name, I left mine default, it doesn’t matter since we only have 1.

Next screen, make sure you set it to untagged VLAN.

Next screen, select No to adding more VLANS.

Next Screen, Select comm
it changes to the system, and click Finish. It will take a few seconds to
configure everything and then it will take you back to the BACS screen.

Notice the Offload Capabilities line, TOE should be there.

Looking at the VLAN information, it shows that
the IP is assigned by DHCP, which we will want to

Changing the IP of the Team

To change the static IP of the team, you will go into Control Panel and you will see a new Network
Adapter. If you named your team the same as mine, it will say NVR Te
am / VLAN 1.

If you look at the status of the individual NICs, you will see that they do not have an IP assigned to them.
It is all being managed by the Team NIC.

After you assign your Static IP to the Team NIC, it will say that there are multiple gat
eways , just click
Yes. It is just a warning, it doesn’t check anything.

If you run an IPCONFIG /ALL you should see something like below

You will see that you only see the Team NIC not the individual ones. And you will see the new static IP
that you

assigned to the virtual adapter.

Data Transfer

You are now finished!!

Here is a picture of the throughput of a 2.5GB file on our internal network running on a gigabit switch.

TOE will make more of a difference with multiple TCP/IP Connections, th
is was just a single file transfer.
