Adapter Port Channels
Anadapter portchannel groupsall thephysical links from a Cisco UCS VirtualInterface Card (VIC) to an
IOMinto one logical link.
Adapterport channelsare created andmanaged internally by Cisco UCS Manager when it detects that the
correcthardware is present. Adapter port channels cannot be configured manually. Adapter port channels are
viewableusing the Cisco UCS ManagerGUI or Cisco UCS Manager CLI

Viewing Adapter Port Channels

Procedure
Step 1 Inthe Navigation pane, clickthe Equipmenttab.
Step 2 Onthe Equipment tab, expand Equipment >Chassis >Chassis_Number >Servers >Server_Number >
InterfaceCards
Step 3 Clickthe adapter for which you want to view the adapter port channels.
Step 4 Inthe Work pane, click the DCE Interfaces tab.
Step 5 Toview details of the adapter port channel, click the link in the Port Channel column.
Fabric Port Channels
Fabricport channels allow you to group several of the physical links from an IOM to a fabric interconnect
intoone logical link for redundancy and bandwidth sharing. As long as one link in the fabric port channel
remainsactive, the fabric portchannel continuesto operate.
Ifthe 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
specificchassis.
Foreach IOM there is a single fabric port channel. Each uplink connecting an IOM to a fabric interconnect
canbe configured as a discrete link or included in the port channel, but an uplink cannot belong to more than
onefabric port channel. For example, if a chassis with two IOMs is discovered and the chassis discovery
policyis configured to createfabric 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
chassiscan join these fabric port channels. Similarly, uplinks belonging to the fabric port channel for IOM-1
cannotjoin the fabricport channelfor IOM-2.
