Scenario 1:2 – Multiple Simple Networks with Active\Active Uplinks and Optional Link Aggregation 802.3ad (LACP) - Windows

Defining two new vNet via GUI
Create a vNet and name it “vNet-PROD-1”
•
On the Virtual Connect Manager screen, click Define, Ethernet Network to create a vNet
•
Ether the Network Name of “vNet-PROD-1”
a.
Optionally select Smart Link, but, do NOT select any of the other options (ie; Private
Networks etc.)
•
Select Add Port, then add the following ports;
a.
Enclosure 1, Bay 1, Port 1
•
Leave Connection Mode as Auto
•
Select Apply
Create a vNet and name it “vNet-PROD-2”
•
On the Virtual Connect Manager screen, click Define, Ethernet Network to create a vNet
•
Ether the Network Name of “vNet-PROD-2”
a.
Select Smart Link, but, do NOT select any of the other options (ie; Private Networks etc.)
•
Select Add Port, then add the following ports;
a.
Enclosure 1, Bay 2, Port 1
•
Leave Connection Mode as Auto
•
Select Apply
Note: By creating TWO vNets we have provided a redundant path to the network. As each uplink
originates from a different VC module and vNet both, uplinks will be active. This configuration provides
the ability to lose an uplink cable, network switch or depending on how the NICs are configured at the
server (teamed or un-teamed), even a VC module.
Note: Smart Link – In this configuration Smartlink SHOULD be enabled. Smartlink is used to turn off
downlink ports within Virtual Connect if ALL available uplinks to a vNet or SUS are down. In this scenario
if an upstream switch or all cables to a vNet were to fail on a specific vNet, VC would turn off the
downlink ports connect to that vNet, which would then force the NIC Teaming software to fail-over to the
alternate NIC.
Defining a new vNet via CLI
The following command(s) can be copied and pasted into an SSH based CLI session with Virtual Connect
# Create the vNet "vNet-PROD" and configure uplinks as discussed above
add Network vNet-PROD-1
add uplinkport enc0:1:1 Network=vNet-PROD-1 speed=auto
set network vNet-PROD-1 SmartLink=Enabled
add Network vNet-PROD-2
add uplinkport enc0:2:1 Network=vNet-PROD-2 speed=auto
set network vNet-PROD-2 SmartLink=Enabled
