Procedure
PurposeCommand or Action
The Ethernet switching mode must be in End-Host
Mode for Cisco UCS to be able to communicate with
upstream disjoint L2 networks.
Configure Ethernet switching mode for both
fabric interconnects in Ethernet End-Host
Mode.
Step 1
See Configuring Ethernet Switching Mode.
See Configuring Ports and Port Channels, on page
77.
Configure the ports and port channels that
you require to carry traffic for the disjoint
L2 networks.
Step 2
(Optional)
See Configuring LAN Pin Groups, on page 293.
Configure the LAN pin groups required to
pin the traffic for the appropriate uplink
Ethernet ports or port channels.
Step 3
These can be named VLANs or private VLANs. For
a cluster configuration, we recommend that you create
Create one or more VLANs.
Step 4
the VLANs in the VLAN Manager and use the
Common/Global configuration to ensure they are
accessible to both fabric interconnects.
See Creating a VLAN for an Upstream Disjoint L2
Network, on page 325.
When this step is completed, traffic for those VLANs
can only be sent through the trunks for the assigned
ports and/or port channels.
Assign the desired ports or port channels
to the VLANs for the disjoint L2 networks.
Step 5
Assigning Ports and Port Channels to VLANs, on
page 327
You can complete this configuration through one or
more vNIC templates or when you configure the
networking options for the service profile.
Ensure that the service profiles for all
servers that need to communicate with the
disjoint L2 networks include the correct

the vNICs send the traffic to the appropriate
VLAN.
Creating a VLAN for an Upstream Disjoint L2 Network
For upstream disjoint L2 networks, we recommend that you create VLANs in the VLAN Manager.
