Oracle® Enterprise Manager

Overview of the Plug-In

By deploying the plug-in to your Grid Control environment, you gain the following management features:

• Monitor Cisco Switch targets.

• Raise alerts and violations based on thresholds set on monitoring and configuration data.

• Provide rich out-of-box metrics and reports based on the gathered data.

Versions Supported

This plug-in supports the following versions of products:

• Oracle Exadata Storage Server 11g Release 2 (11.2) and later

• Enterprise Manager Grid Control 11g Release 1 (11.1) and later

Prerequisites

The following prerequisite must be met before you can deploy the plug-in:

• For all Management Agents on which the Cisco switch plug-in is deployed, you must set and validate the preferred credentials in Enterprise Manager.

Deploying the Plug-In

After you ensure that the prerequisites are met, follow these steps to deploy the plug-in to the appropriate Management Agents.

1. Download the Cisco Switch Plug-In archive file to your desktop or computer on which the browser is launched. You can download the archive from Oracle Technology Network (OTN).

2. Log in to Enterprise Manager Grid Control as SYSMAN.

3. Click Setup from the upper-right-corner of the Grid Control Home page, then click Management Plug-ins from the left-side menu of the Setup page.

4. Click Import.

5. Click Browse. Navigate to the directory where you have downloaded the plug-in JAR file. Select the JAR file, then click OK.

6. Click List Archive. The plug-ins within the selected JAR file appear in a list.

7. Select the check box for the Cisco Switch version 1.2 and click OK.

8. Verify that you have set preferred credentials on all Agents where you want to deploy the plug-in.

9. In the Management Plug-ins page, click the icon in the Deploy column for the plug-in.

   The Deploy Management Plug-in wizard appears.

10. Click Add Agents.

11. Select Agent from the Target Type pull down menu.

12. Select the Agent(s) you want to deploy the plug-in to, then click Select.

13. Click Next, then click Finish. The plug-in is deployed to the selected Agents.

    If you see an error message stating that the preferred credential is not set up, go to the Preferences page and add the preferred credentials for the Agent target type. To go to the Preferences page, click Preferences from the top-right corner of the Grid Control page.

Hardware Configuration

Follow the below steps to configure Cisco switch for EM plug-in (the Cisco switch host name in the example below is 'dm01sw-ip'):

1. Login to the Cisco switch and enter Configure mode:

   # telnet dm01sw-ip User Access Verification Password:  dm01sw-ip> enable
   Password:  dm01sw-ip# configure terminal Enter configuration commands, one per line.  End with CNTL/Z. dm01sw-ip(config)#
    
   

2. Enable access to allow the plug-in to poll the switch. In the command, <EMagentIPaddr> is the IP address of the server where the EM Agent is running that has the EM Cisco Switch Management Plug-In deployed. The SNMP community specified must match the value provided during EM Cisco Switch Management Plug-In setup:

   dm01sw-ip(config)# access-list 1 permit <EMagentIPaddr> 
   dm01sw-ip(config)# snmp-server community <community_string> ro 1
    
   

3. Set the EM Cisco Switch Management Plug-In as the location where SNMP traps are delivered. The SNMP community specified must match the value provided during EM Cisco Switch Management Plug-In setup:

   dm01sw-ip(config)# snmp-server host <EMagentIPaddr> version 1 <community string> udp-port <EMagentRecvltListenPort>
    
   

   Where EMagentRecvltListenPort is the EMD_URL port of emagent or SnmpRecvletListenNIC property value if it is enabled.

4. Configure the switch to send only environmental monitor SNMP traps:

   dm01sw-ip(config)# snmp-server enable traps envmon
    
   

5. Verify settings and save the configuration:

   dm01sw-ip(config)# end 
   dm01sw-ip# show running-config 
   dm01sw-ip# copy running-config startup-config 
   

Adding Cisco Switch Targets for Monitoring

After successfully deploying the plug-in, follow these steps to add the Cisco Switch target to Grid Control for central monitoring and management:

1. Click the Targets tab, the click All Targets.

2. Select Agent from the “Search” pull down menu. Enter the server hostname of the first database server name in your cluster in the search field, then click Go.

3. Click on the Agent you want to add as a target (sclczdb01.us.oracle.com:3872 in the example below). IMAGE

4. Select the Cisco Switch target type from the “Add” pull down menu, then click Go.

5. Enter the following parameters in the Add Cisco Switch page:

   • Name: Enter the switch name, which should match the Cisco Switch hostname

   • Hostname or IP Address: Enter the switch name

   • SNMP Read Community String: Accept the default value

   • SNMP Timeout: Accept the default value

6. Click Test Connection to make sure the parameters you entered are correct.

7. If the test is successful, click OK.

Verifying Hardware Configuration

Using the snmpwalk command line utility or equivalent tool, Cisco switch configuration can be verified.

Running the following command should fetch the data from the Cisco switch and display them:

snmpget –v 1 –c <community_string> <hostname_of_cisco_switch> 1.3.6.1.4.1.9.2.1.56.0

Verify the Cisco Switch Plug-in

This section provides the steps to validate that the plug-in can collect the metrics through SNMP queries.

Prerequisites:

• Install the plug-in.

• Configure the Cisco switch for accepting SNMP queries from the EM Agent and send trap information to the EM Agent host and recvlt listening ports (default recvlt listening port is EMD_URL port).

Verify:

To verify the Cisco switch is configured correctly for responding to SNMP queries from the EMAgent:

• In the EM console, go to the Cisco switch target page.

• The All metrics link should show all the data collected.

• The Alert history link should show the events generated, if any.

Setting Up Alerts

After configuring the Cisco Switch targets to send SNMP alerts, set up alerts in Grid Control.

1. Log in to Enterprise Manager Grid Control as SYSMAN.

2. Click the Targets tab, then All Targets.

3. In the All Targets page, from the Search list, select Cisco Switch and click Go.

4. Click the target you are interested in. The target home page appears.

5. Click Metric and Policy Settings in the Related Links section of the page.

6. In the Metric and Policy Settings page, you can modify metric threshold values, edit monitoring settings for specific metrics, change metric collection schedules, and disable collection of a metric.

   You can modify the thresholds directly in the table or click the edit icon (pencil icon) to access the Edit Advanced Settings page. For more information on the fields displayed in this page and how the thresholds can be modified, click Help from the top-right corner of this page.
