Adapter Port Channels
An adapter port channel groups all the physical links from a Cisco UCS Virtual Interface Card (VIC) to an
IOM into one logical link.
Adapter port channels are created and managed internally by Cisco UCS Manager when it detects that the
correct hardware is present. Adapter port channels cannot be configured manually. Adapter port channels are
viewable using the Cisco UCS Manager GUI or Cisco UCS Manager CLI
Viewing Adapter Port Channels
Procedure
Step 1
In the Navigation pane, click the Equipment tab.
Step 2
On the Equipment tab, expand Equipment > Chassis > Chassis_Number > Servers > Server_Number >
Interface Cards
Step 3
Click the adapter for which you want to view the adapter port channels.
Step 4
In the Work pane, click the DCE Interfaces tab.
Step 5
To view details of the adapter port channel, click the link in the Port Channel column.
Fabric Port Channels
Fabric port channels allow you to group several of the physical links from an IOM to a fabric interconnect
into one logical link for redundancy and bandwidth sharing. As long as one link in the fabric port channel
remains active, the fabric port channel continues to operate.
If the correct hardware is connected, fabric port channels are created by Cisco UCS Manager in the following
ways:
• During chassis discovery according to the settings configured in the chassis discovery policy.
• After chassis discovery according to the settings configured in the chassis connectivity policy for a
specific chassis.
For each IOM there is a single fabric port channel. Each uplink connecting an IOM to a fabric interconnect
can be configured as a discrete link or included in the port channel, but an uplink cannot belong to more than
one fabric port channel. For example, if a chassis with two IOMs is discovered and the chassis discovery
policy is configured to create fabric port channels, Cisco UCS Manager creates two separate fabric port
channels: one for the uplinks connecting IOM-1 and another for the uplinks connecting IOM-2. No other
chassis can join these fabric port channels. Similarly, uplinks belonging to the fabric port channel for IOM-1
cannot join the fabric port channel for IOM-2.
