Global configuration policies

Most of the policy configurations are assigned to the servers by assigning those policies to service profiles associated with physical servers. There are a few global configuration policies for UCS infrastructure that are not assigned to servers but are necessary for proper functioning of all the components.

These policies include the following:

  • Chassis/FEX Discovery Policy
  • Power Policy
  • MAC Address Table Aging
  • DNS Server
  • Time Zone Management
  • SNMP

These policies are configured under various Navigation pane tabs. We will now look into the configuration of each of these policies.

Chassis/FEX Discovery Policy

This is the first policy needed to be configured so that the UCS chassis is detected by the UCSM software. It has been highlighted in the following screenshot:

Chassis/FEX Discovery Policy

Following are the steps to configure this policy:

  1. Log in to the UCSM screen.
  2. Click on the Equipment tab in the Navigation pane.
  3. Select Policies from the Work pane and click on Global Policies.
  4. In the Chassis/FEX Discovery Policy area of the Work pane, from the Action drop-down menu, select the option with the number of connections that is equal to or less than the actual number of physical connections from IOM/FEX of chassis to the FIs.
  5. Click on OK.

Power Policy

  1. Follow the same steps as you did for Chassis/FEX Discovery Policy and select Global Policies.
  2. Select the appropriate Redundancy option, which is dependent on the total number of power supplies and power feeds to the datacenter.
  3. Click on OK.

MAC Address Table Aging

  1. Follow the same steps as you did for Chassis/FEX Discovery Policy and select Global Policies.
  2. Select the appropriate Aging Time option from the available radio buttons.
  3. Click on OK.

The other global policies to be configured are under the Admin tab in the Navigation pane. Go through the following sections to get an idea of the set of steps required to configure these settings.
