The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
This chapter includes the following sections:
Configuring the Chassis Discovery Policy
This discovery policy determines how the system reacts when you add a new chassis. If you create a chassis discovery policy, Cisco UCS Manager configures the chassis for the number of links between the chassis and the fabric interconnect specified in the policy.
Configuring the Power Policy
The power policy is a global policy that specifies the redundancy for power supplies in all chassis in the Cisco UCS instance. This policy is also known as the PSU policy.
For more information about power supply redundancy, see Cisco UCS 5108 Server Chassis Hardware Installation Guide.
Configuring the Aging Time for the MAC Address Table
To efficiently switch packets between ports, the fabric interconnect maintains a MAC address table. It dynamically builds the MAC address table by using the MAC source address from the packets received and the associated port on which the packets were learned . The fabric interconnect uses an aging mechanism, defined by a configurable aging timer, to determine how long an entry remains in the MAC address table. If an address remains inactive for a specified number of seconds, it is removed from the MAC address table.
You can configure the amount of time (age) that a MAC address entry (MAC address and associated port) remains in the MAC address table.
