Chassis/FEX Discovery Policy
The chassis/FEX discovery policy determines how the system reacts when you add a new chassis or FEX. Cisco UCS uses the settings in the chassis/FEX discovery policy to determine:
- the minimum threshold for the number of links between the chassis or FEX and the fabric interconnect
- whether to group links from the IOM to the fabric interconnect in a fabric port channel
For more information about chassis links, including an overview of how the chassis/FEX discovery policy works in a multichassis Cisco UCS domain, see the Cisco UCS Manager configuration guides.
Configuring the Chassis/FEX Discovery Policy
You can configure a chassis policy to specify how the system reacts when a new chassis is added.
On Compute page, choose the pod that includes the Cisco UCS Manager account.
Click Equipment Global Policies.
Check the Chassis/FEX Discovery Policy check box.
From the Action drop-down list, choose the minimum threshold for the number of links between the chassis or Fabric Extender (FEX) and the fabric interconnect:
From the Link Grouping Preference drop-down list, choose whether the links from the IOMs or FEXes to the fabric interconnects are grouped in a port channel.
