The DCNM-LAN client user interface, shown in Figure 13-1, presents device status information and provides configuration tools that allow you to manage devices. It is divided into the panes shown in Figure 13-1. When you want to view information about a specific object in a managed device or want to perform a configuration task, you use the panes in the order shown in Figure 13-1.
Figure 13-1 DCNM-LAN Client User Interface
Feature Selector pane
Feature Selector Pane
The Feature Selector pane, shown in Figure 13-1, allows you to see features grouped by categories and to choose the feature that you want to use or configure. The bottom section of the Feature Selector pane displays buttons for feature categories. When you choose a category, the top section of the Feature Selector pane displays a tree of features within the chosen category.
In Figure 13-1, the Interfaces category is chosen, so the tree shows features that allow you to configure the interfaces of managed devices.
The documentation and online help for DCNM-LAN includes many procedures that begin with choosing the applicable feature from the Feature Selector pane. For example, a procedure about configuring an Ethernet interface would start with the following step:
From the Feature Selector pane, choose Interfaces > Physical > Ethernet .
After you choose a feature on the tree, the Contents pane displays information about the feature.
The Contents pane, shown in Figure 13-1, displays information about the currently selected feature and provides fields for configuring that feature. The Contents pane contains two smaller panes: the Summary pane and the Details pane.
The Summary pane, shown in Figure 13-1, displays an organized set of objects that you can view information about or perform actions on. The type of objects that appear depends upon the currently selected feature.
For example, if you choose Interfaces > Physical > Ethernet from the Feature Selector pane, the Summary pane shows a table of devices. You can expand the managed devices to view the slots that contain network interface cards. You can expand the slots to view the interfaces they contain and key information about the status of the interfaces, such as the port mode, administrative status, and operational status. For most features, the title bar for the Summary pane shows what you have selected.
After you choose the object that you want to view or configure, the Details pane displays information about the selected object, such as an Ethernet interface.
Exporting the Summary Pane
You can export the data shown in the Summary pane to a spreadsheet in Microsoft Excel 97-2003 format. To do so, click the green arrow in the upper-right corner of the Summary pane and specify the filename and location for the spreadsheet.
Filtering the Summary Pane
For many features, you can filter the objects that appear in the Summary pane. If filtering is supported for the feature that you selected, you can enable filtering from the menu bar by choosing View > Filter. In the Summary pane, the columns that you can use to filter the objects become drop-down lists. To filter the Summary pane, use the drop-down column heading lists to limit the objects that appear.
The Details pane, shown in Figure 13-1, shows information and configuration fields that are specific to the object that you selected in the Summary pane. The Details tab is often further divided into tabs. You can click on a tab to view its contents.
Events—You can use this tab to view feature-specific events about the selected object. For more information, see the System Management Configuration Guide, Cisco DCNM for LAN, Release 5.x .
Sections provide further organization of related fields and information. The DCNM-LAN client allows you to expand and collapse sections so that you can show or hide fields and information as needed. For example, as shown in Figure 13-1, on the Port Details tab, the Basic Settings section is expanded but the Port Mode Settings section is collapsed.
The DCNM-LAN client also includes the Association pane, which allows you to access objects that you have configured in features that are associated with the currently selected feature. Figure 13-2 shows the Association pane.
When tabs appear on the right side of the DCNM-LAN client, you can click on them to access the Association pane. For example, as shown in Figure 13-2, if you are configuring an Ethernet interface, you can use the Association pane to access the IPv4 ACLs that you can apply to the interface. If you right-click on an IPv4 ACL in the Association pane, you can choose to apply the ACL to the interface or to go to the IPv4 ACLs feature and configure the ACL.
Figure 13-2 Association Pane
The menu bar in the DCNM-LAN client includes the following standard menus that appear:
New—Allows you to create new objects. The types of objects that you can create depends upon the currently selected feature. In some cases, the object selected in the Summary pane also affects what you can create.
Deploy—Saves your changes to the DCNM-LAN server and deploys configuration changes to managed devices.
Exit—Closes the DCNM-LAN client.

Multiple Platform Support
DCNM-LAN supports several types of Cisco Nexus platforms; however, some of the features supported in DCNM-LAN are not supported or applicable to all platforms. This section describes how DCNM-LAN handles unsupported features in the user interface.
Unsupported Features—If a platform does not support a particular feature, the platform is not displayed for that feature.
For example, if you choose Security > Access Control > Time-range from the Feature Selector pane, the Summary pane displays only the platform types that support the Time-range feature. In this case, the Cisco Nexus 1000V does not support this feature, so any managed Cisco Nexus 1000V platforms are not displayed in the Summary pane. Similarly, the Time-range association pane does not include any Cisco Nexus 1000V platforms.
Unsupported Attributes—Sometimes a platform supports a feature, but does not support a particular attribute in that feature. In this case, the attribute is grayed-out or a N/A (Not Applicable) value is displayed in the field or cell.
If all attributes grouped in a particular section are not supported, N/A is added to the section title, and DCNM-LAN does not allow you to expand the section.
If all attributes in a tab are not supported for a particular platform, the tab is displayed, but if you click on it, a message appears stating that the attribute is not supported.
Unsupported Charts—If a platform does not support some attributes in a chart, DCNM-LAN grays out those attributes. If a platform does not support any attributes in a chart, when you select the chart, DCNM-LAN displays a message stating that the chart is not supported.
Unsupported Options—If a platform does not support an option, the option is not displayed, for example, in drop-down lists.
Unsupported Operations— If a platform does not support an option for a specific operation on a context or toolbar menu, the option is grayed-out.
Opening the DCNM-LAN Client
You can open the DCNM-LAN client after you have installed the DCNM-LAN client on the computer that you are using.
Step 2 In the DCNM Server field, enter the IP address or hostname of the DCNM-LAN server. You can use the hostname only if your DNS server has an entry for the DCNM-LAN server hostname. If you have previously logged into the server with the current client installation, you may be able to choose the IP address or hostname from the drop-down list.
Note If your DCNM-LAN deployment uses a clustered-server environment, enter the DNS name or IP address of the master DCNM-LAN server.
Step 3 In the Username field, enter the name of the DCNM-LAN server user account that you want to use to access the DCNM-LAN client.
Step 4 In the Password field, enter the password for the user account that you specified.
Step 5 (Optional) If you need to change the DCNM-LAN server port, do the following:
a. If the Port field is not visible, click More >>.
b. Enter the port number in the Port field.
The default DCNM-LAN server port number is 1099; however, you can specify a different port number when you install or reinstall the DCNM-LAN server.
Step 6 (Optional) If you need to use a proxy server to connect to the DCNM-LAN server, do the following:
a. If the “Connect to the DCNM-LAN server with a proxy server” check box is not visible, click More >> .
b. Check Connect to the DCNM server with a proxy server .
The Proxy Server area appears below the check box.
c. In the Address field, enter the IP address of the proxy server.
d. In the HTTP Port and Socks Port fields, enter the port numbers on which the proxy server accepts HTTP and Socks connections.
e. (Optional) If the proxy server requires authentication, check Authentication and enter a valid username and password in the fields provided.
Step 7 Click Login .
The DCNM-LAN client user interface appears.
If a dialog box displays a message about device credentials, you have not configured device credentials for the user account that you specified.
Step 8 If a dialog box shows a message that your device credentials are not set, do one of the following:
If you want to set device credentials now, click Yes .
If you do not want to set device credentials now, click No .
You can close the DCNM-LAN client when you are done using it.
Step 1 From the menu bar, choose File > Exit .
A dialog box displays a confirmation message.
Step 2 (Optional) If you have not deployed your changes, do one of the following:
If you want to save your changes, including deploying configuration changes to managed devices, check Save pending changes .
If you want to discard your changes, uncheck Save pending changes .
Step 3 Click Yes .
If you started any statistical data collection processes during the DCNM-LAN client session, a dialog box displays the collection processes.
Step 4 If a dialog box displays the statistical data collection processes that you started, do the following:
a. Decide which statistical collection processes that you want to stop.
Note We recommend that you stop any unnecessary statistical collection processes when you log out of the DCNM-LAN client.
b. Check the collection processes that you want to stop. If you want to stop all of your collection processes, click Select All .
c. Click Ok .
When you use the DCNM-LAN client to make configuration changes to managed devices or to the DCNM-LAN server, you may need to deploy the changes or the DCNM-LAN client may deploy them automatically, depending upon what changes you have made.
Automatic deployment—If the DCNM-LAN client deploys a change automatically, the “Deploying configuration” message appears briefly. For example, if you delete an access rule from an ACL, the DCNM-LAN client immediately deploys this configuration change to the managed device that has the ACL.
Manual deployment—If the DCNM-LAN client is storing a configuration change, on the toolbar, the Deploy button is available. For example, if you change the sequence number of an access rule of an ACL, the DCNM-LAN client stores this configuration change until you manually deploy it to the managed device that has the ACL.
To remind you of the necessity to deploy changes that the DCNM-LAN client is storing, the procedures in the DCNM-LAN documentation set include a deployment step.
Deploying server changes saves your changes on the DCNM-LAN server. For example, if you add a DCNM-LAN server user account, deploying your changes adds the user account to the DCNM-LAN server and does not affect managed devices.
Deploying configuration changes to a managed device causes the DCNM-LAN server to update the running configuration of the device.
Note DCNM-LAN does not update the startup configuration of a managed device. When you want to replace the startup configuration of a managed device with the running configuration, you can log into the command-line interface of the device and copy the running configuration to the startup configuration.
When you close the DCNM-LAN client and you have not deployed your changes, you can deploy them without canceling the process of closing the DCNM-LAN client. For more information, see the “Closing the DCNM-LAN Client” section.
Working with Statistics and Charts
This section describes how to use the statistical charts available on a Statistics tab.
You can use a Statistics tab to start and stop statistical monitoring for an object and to work with charts of statistical data about the selected object. For each chart, the DCNM-LAN client also provides overview charts, which allow you to see historical trends and to control the time scale of the standard chart.
The following table shows the licensing requirements for this feature:
Real-time monitoring requires no license.
Cisco DCNM-LAN requires a LAN Enterprise license for the following features:
Maintaining a history of statistical data
Using overview charts
For information about obtaining and installing a Cisco DCNM-LAN LAN Enterprise license, see the Cisco DCNM Installation and Licensing Guide, Release 5.x .
Accessing a Chart

Using an Overview Chart
You can use an overview chart to view the historical trend of the statistical data of the current chart and to set the time scale of the standard chart.
Pre Provision—Controls whether the DCNM-LAN client displays some settings only when other settings are made or whether the DCNM-LAN client always displays all settings. For more information, see the “Configuring Preprovisioning” section.
Configuring Monitoring Preferences
You can configure the default frequency for statistical data retrieval from monitored devices. The default frequency for statistical data retrieval is 30 seconds. This frequency determines the initial data retrieval frequency for a new chart. Users can override the default frequency by configuring the chart-specific setting.
You can also configure whether the DCNM-LAN client automatically opens statistical charts when you access the Statistics tab of an object for which DCNM-LAN is already collecting statistical data.
BEFORE YOU BEGIN
Determine how often you want DCNM-LAN to retrieve statistical data by default. Consider how important it is to your organization that charts update frequently. If very current charting data is important to your organization, consider using a short data retrieval frequency.
Step 1 From the menu bar, choose Tools > Preferences .
The Global Preferences dialog box appears. Under Monitoring, the Default Monitoring Frequency drop-down list displays the current frequency for statistical data retrieval.
The default polling frequency is 30 seconds.
Step 2 If you want to configure the default frequency of statistical data retrieval, from the Default Monitoring Frequency drop-down list, choose the new data retrieval frequency.
Step 3 If you want to configure the default behavior when you access the Statistics tab of an object for which DCNM-LAN is already collecting statistical data, do one of the following:
If you want the client to show charts without asking for confirmation, check the Load history charts by default check box.
If you want the client to prompt you for confirmation before it opens statistical charts, uncheck the Load history charts by default check box.
Step 4 Click Ok .
Configuring the Maximum Age of Events Fetched from the Server
You can configure the maximum age of events that the DCNM-LAN client fetches from the DCNM-LAN server when you start the DCNM-LAN client. This setting affects how old the events are that the DCNM-LAN client displays in the Event Browser and on feature-specific Events tabs. By default, the DCNM-LAN client fetches events that occurred up to 1 hour prior to the DCNM-LAN client startup. You can configure the DCNM-LAN client to fetch events that are up to 24 hours old.
Step 1 From the menu bar, choose Tools > Preferences .
The Global Preferences dialog box appears. Under Events, the Fetch events before drop-down list displays the current maximum age of events.
Step 2 From the Fetch events before drop-down list, choose the new maximum age of events.
Note To prevent the DCNM-LAN client from fetching any old events, choose zero (0) hours as the maximum age of events. When you choose zero hours, the DCNM-LAN client shows only the events that the DCNM-LAN server receives after you start the DCNM-LAN client.
Step 3 Click Ok .
Preprovisioning refers to configuring a managed device with settings for modes or protocols that are not enabled. The preprovisioning preference affects the following sections of the DCNM-LAN client interface:
Interfaces > Physical > Ethernet > Device > Slot > Interface, Port Details tab, Port Mode Settings section
When you enable preprovisioning, the DCNM-LAN client displays all port mode fields regardless of the setting in the Mode drop-down list. When you disable preprovisioning, the DCNM-LAN client displays only the port mode settings that are relevant to the currently selected port mode. For example, if preprovisioning is disabled and you choose Trunk from the Mode drop-down list, the DCNM-LAN client displays only the Trunk settings and hides the Access, PVLAN Host, and PVLAN Promiscuous fields.
Additionally, the dialog boxes for configuring the Access VLAN field and the Native VLAN field include the Create in the Device check box. When you enable preprovisioning, you can uncheck this check box if you want DCNM-LAN to configure the device to refer to a VLAN that is not currently configured. When you disable preprovisioning, this check box is always checked and DCNM-LAN creates the VLAN specified, if it does not already exist.
Switching > Spanning Tree > Device, Configuration tab, Global Settings section
When you enable preprovisioning, the DCNM-LAN client displays MST settings regardless of the settings in the Protocol drop-down list. When you disable preprovisioning, the DCNM-LAN client displays the MST Setting fields unless you choose MST from the Protocol drop-down list.
Step 1 From the menu bar, choose Tools > Preferences .
The Global Preferences dialog box appears. Under Pre Provision, the Pre Provision check box appears.
Step 2 Do one of the following:
If you want to enable preprovisioning, ensure that the Pre Provisio n check box is checked.
If you want to disable preprovisioning, ensure that the Pre Provision check box is unchecked.
Step 3 Click Ok .
