Fabric Interconnect ports configured as uplink ports are used to connect to northbound upstream network switches. These uplink ports can be connected to upstream switch ports as individual links or links configured as port channels (PC), which provides bandwidth aggregation as well as link redundancy.

The Fabric Interconnect port channel configuration is based on LACP. It is also possible to configure a port channel as a vPC where port channel uplink ports from a Fabric Interconnect are connected to different upstream switches.

It is recommended to configure Fabric Interconnect uplink ports in vPC configuration, as shown in the following diagram:

The following are the steps to configure the ports and the port channels for the preceding network topology:

1. Log into UCS Manager.
2. Click on the Equipment tab in the navigation pane.
3. In the Equipment tab, click on a Fabric Interconnect.
4. In the work area pane, select LAN Uplinks Manager.
5. Expand Ports in the Fixed Module or Expansion Module (if present).
6. Right-click on a single port or hold the Ctrl key and select multiple ports.
7. Select Configure as Uplink Port.
8. A pop-up menu will allow us to configure a new status for the port(s).
9. Select the new port status and click on Yes.

Repeat these steps to configure all the uplink ports for both Fabric Interconnects.

After all the uplink ports are configured, a port channel can be created for these ports by performing the following steps:

1. Right-click on a Fabric Interconnect in the middle pane labeled Port Channel and Uplinks of LAN Uplinks Manager.
2. Click on Create Port Channel.

3. In the pop-up window, assign an ID and a name for the port channel and click on Next.

4. In the next window, click the uplink ports which should be added to the port channel and click on the arrow sign to add ports to the port channel.
5. After adding ports, click Finish to complete the port channel configuration:
