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 Chassis Discovery Policy
Procedure
Step 1
In the
Navigation pane, click the
Equipment tab.
Step 2
Click the Equipment node.
Step 3
In the
Work pane, click the
Policies tab.
Step 4
Click the
Global Policies subtab.
Step 5
In the Chassis Discovery Policy area, choose the number of
links to be used by the chassis from the Action drop-down list.
Step 6
In the
Power Policy area, click one of the following radio buttons in the
Redundancy field:
non-redundant—All installed power supplies are turned on and the load is evenly balanced. Only smaller configurations (requiring less than 2500W) can be powered by a single power supply.
n+1—The total number of power supplies to satisfy non-redundancy, plus one additional power supply for redundancy, are turned on and equally share the power load for the chassis. If any additional power supplies are installed, Cisco UCS Manager sets them to a "turned-off" state.
grid—Two power sources are turned on, or the chassis requires greater than N+1 redundancy. If one source fails (which causes a loss of power to one or two power supplies), the surviving power supplies on the other power circuit continue to provide power to the chassis.

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.

Guide.

Configuring the Aging Time for the MAC Address Table
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.
Configuring the Aging Time for the MAC Address Table
Procedure
Step 1
In the
Navigation pane, click the
Equipment tab.
Step 2
Click the Equipment node.
Step 3
In the
Work pane, click the
Policies tab.
Step 4
Click the
Global Policies subtab.
Step 5
In the MAC Address Table Aging area, complete the following fields:
Name
Description
Aging Time field
The length of time an idle MAC address remains in the MAC address table before it is removed by Cisco UCS. This can be:
never—MAC addresses are never removed from the table regardless of how long they have been idle.
mode-default—The system uses the default value. If the fabric interconnect is set to end-host mode, the default is 7,200 seconds. If it is set to switching mode, the default is 300 seconds.
other—Cisco UCS Manager GUI
displays the Seconds field which allows you to enter a custom value.
Seconds field
The number of seconds a MAC address must remain idle before Cisco UCS removes it from the MAC address table. This field is only visible if you choose other for the aging time.
