About Cisco IMC Supervisor

Cisco IMC Supervisor is a management system that allows you to manage rack-mount servers on a large scale. It allows you to create groups of rack-mount servers for monitoring and inventory purposes. If Cisco IMC Supervisor is installed as a connector for exiting UCS Director, then Cisco IMC Supervisor configuration supersede the default Cisco IMC installation and display only Cisco IMC Supervisor related menu options and tabs.

You can use Cisco IMC Supervisor to perform the following tasks:

- Logically grouping servers and viewing summary per group

- Collecting inventory for the managed servers

- Monitoring servers and groups

- Managing firmware including firmware download, upgrade, and activation

- Provide Northbound REST APIs to discover, monitor and manage servers and perform firmware upgrades programmatically.

- Managing standalone server actions including power control, LED control, log collection, KVM launch, and CIMC UI launch.

- Restricting access using Role Based Access Control (RBAC)

- Configuring email alerts

- Configuring server properties using policies and profiles

- Defining schedules to defer tasks such as firmware updates or server discovery

- Diagnosing server hardware issues using UCS Server Configuration Utility

- Cisco Smart Call Home provides proactive diagnostics, alerts, and remediation recommendations

About Licenses

Cisco IMC Supervisor requires you to have the following valid licenses:

- A Cisco IMC Supervisor base license.

- A Cisco IMC Supervisor bulk endpoint enablement license that you install after the Cisco IMC Supervisor base license.

- A Cisco IMC Supervisor advanced license. You can add, edit, and delete policies and profiles with the base license but you cannot apply a policy or a profile to a server without the advanced license. An error occurs if this license is unavailable when you apply a policy.

- A default embedded Cisco IMC Supervisor evaluation license. The evaluation license is generated automatically when the end user installs Cisco IMC Supervisor and all the services start for the first time. It is applicable for 50 servers.

Important:
If you are using an evaluation license for Cisco IMC Supervisor, note that when this license expires (90 days from the date the license is generated), retrieving inventory and system health information, such as faults, will not work. You will not be able to refresh system data, or even add new accounts. At that point, you must install a perpetual license to use all features of Cisco IMC Supervisor.

The process for obtaining and installing the licenses is the same. For obtaining a license, perform the following procedures:

1. Before you install Cisco IMC Supervisor, generate the Cisco IMC Supervisor license key and claim a certificate (Product Access Key).

2. Register the Product Access Key (PAK) on the Cisco software license site, as described in Fulfilling the Product Access Key.

3. After you install Cisco IMC Supervisor, update the license as described in Updating the License.

4. After the license has been validated, you can start to use Cisco IMC Supervisor.

For various other licensing tasks you can perform, see Licensing Tasks.
