Configuring Auto Provisioning for Controllers

Auto provisioning allows NCS to automatically configure a new or replace a current wireless LAN controller (WLC). The NCS auto provisioning feature can simplify deployments for customers with a large number of controllers.


Note For Auto Provisioning privileges, you must have Admin, Root, or SuperUser status.



Note To allow or disallow a user Auto Provisioning privileges, edit the permitted tasks using the Administration > AAA > User Groups > group name > List of Tasks Permitted section of NCS. Select or unselect the check box to allow or disallow these privileges.



Note A controller radio and b/g networks are initially disabled by the NCS downloaded startup configuration file. If desired, you may turn on those radio networks by using a template, which should be included as one of the automated templates.



Note To specify the Auto Provision filter contents, you can directly enter the details in the application or import the details from a CSV file. The auto provisioning feature supports the 5500 and non-5500 series of controllers. The non-5500 series controllers have AP manager interface configuration information defined, whereas 5500 series controllers do not have this information.


To access the Auto Provisioning feature, choose Configure > Controller Auto Provisioning.

Auto Provisioning Device Management (Auto Provisioning Filter List)—Allows you to create and edit auto provisioning filters which define the list of allowable devices to be auto provisioned or auto monitored by NCS.

Auto Provisioning Primary Search Key Settings—Provides the ability to set the matching criteria search order.

Auto Provisioning Device Management (Auto Provisioning Filter List)

This feature allows you to create and edit auto provisioning filters which define the list of allowable devices to be auto provisioned or auto monitored by NCS.

Filter parameters include the following:

Filter Name—Identifies the name of the filter.

Filter Enable—Indicates whether or not the filter is enabled.


Note Only enabled filters can participate in the Auto Provisioning process.


Monitor Only—If selected, the WLC defined in this filter is managed by NCS but not configured by NCS if the WLC contacts NCS during the auto provisioning process.

Filter Mode—Indicates the search mode for this filter (Host Name, MAC Address, or Serial Number).

Config Group Name—Indicates the Configuration Group name.


Note All Config-Groups used by auto provision filters should not have any controller defined in them.


Auto Provisioning Options

The Select a command drop-down list has the following options:

Add Filter—Allows you to add an Auto Provisioning filter. See the "Adding an Auto Provisioning Filter" section on page 15-63 for more information.

Delete Filter(s)—Allows you to delete the selected Auto Provisioning filter. See ""Deleting an Auto Provisioning Filter(s)" section on page 15-66" for more information.

List Filter(s) Device Info—Allows you to view details for the selected Auto Provisioning filter. See ""Listing Auto Provisioning Filter(s) Device Information" section on page 15-67" for more information.

List All Filter(s) Device Info—Allows you to view details for all of the Auto Provisioning filter. See ""Listing All Auto Provisioning Filter(s) Device Information" section on page 15-68" for more information.

High Availability

To ensure continued operation in case of failure, NCS now provides a high availability (or failover framework). When an active (primary) NCS fails, a secondary NCS takes over operations (in less than two minutes) for the failed primary NCS and continues to provide service. Upon failover, a peer of the failed primary NCS is activated on the secondary NCS using the local database and files, and the secondary NCS runs a fully functional NCS. While the secondary host is in failover mode, the database and file backups of other primary NCSs continue uninterrupted.

If Email Address is specified in the HA Configuration then Mail Server must be configured and reachable in order to succeed in HA configuration.

For more High Availability information, refer to the following sections:

Guidelines and Limitations for High Availability, page 15-109

Failover Scenario, page 15-109

Performing Background Tasks, page 15-15

High Availability Status, page 15-110

Configuring High Availability on the Primary NCS, page 15-110

Deploying High Availability, page 15-112

User Preferences

Select alarms for Alarm Summary Toolbar—To select alarms for the Alarm Summary Toolbar, click Edit Alarm Categories and choose the required alarm categories and sub-categories.

License Center

The License Center allows you to manage NCS, wireless LAN controllers, and MSE licenses. The License Center is available from the NCS Administration menu. To view the License Center page, choose Administration > License Center (see Figure 15-2).


Note Although NCS and MSE licenses can be fully managed from the License Center, WLC licenses can only be viewed. You must use WLC or CLM to manage WLC licenses.



Tip To learn more about NCS License Center, go to Cisco.com to watch a multimedia presentation. Here you can also find the learning modules for a variety of NCS topics. Over future releases, we will add more overview and technical presentations to enhance your learning.


For more information about NCS licenses, see the "NCS Licenses" section on page 1-3.

Figure 15-2 License Center

NCS License Information

The NCS Licenses portion of the License Center page displays the following:

Feature—The type of license. It can be NCS or DEMO.

Device Limit—The total number of licensed access points and switches.

Device Count—The current number of access points and switches using licenses.


Note AP count includes both associated and unassociated access points. When you are near the AP limit, you can delete any unassociated access points to increase available license capacity. For a demo license, you can click the "If you do not have a Product Authorization Key (PAK), please click here for available licenses" link and choose Wireless Control System Trial License.



Note Autonomous access points are not counted towards the total device count for your license.


% Used—The percentage of access points and switches licensed across NCS. If the percentage drops to 75%, the value appears in red. At this level, a message also appears indicating that both associated and unassociated access points are part of the AP count.

Type—Permanent if all licenses are permanent. If any licenses are evaluations (or demos), it shows the number of days remaining on the license that has the fewest number of days until expiration.


Note To obtain a new license for NCS, go to the Product License Registration link

(https://tools.cisco.com/SWIFT/Licensing/PrivateRegistrationServlet)

and provide your Product Authorization Key (PAK) and host name.



Note If you choose Summary > NCS from the left sidebar menu, only the NCS license information is displayed.


See the Cisco Wireless Control System Licensing and Ordering Guide at this URL:
http://www.cisco.com/en/US/prod/collateral/wireless/ps5755/ps6301/ps6305/product_data_sheet0900aecd804b4646.html#wp9000156.

It covers selecting the correct SKU, ordering the SKU, installing the software, registering the PAK certificate, and installing the license file on the server.

See the "NCS Licenses" section on page B-1 for more information on licensing enforcement, PAK certificates, license types, and installing and managing NCS licenses.

WLC Controller License Information

The Controller Licensing portion of the License Center page provides the following information for both WPLUS and Base licenses:

Controller Count—The current number of licensed controllers.


Note Only 5500 series controllers are included in the count. NCS provides only an inventory view and issues warnings if a license is expiring.



Note Clicking the number in this column is the same as choosing Summary > Controller from the left sidebar menu, except that it is sorted by the feature you select. This page provides a summary of active controllers.


AP Limit—The total number of licensed access points.

Type—The four different types of licenses are as follows:


Note For any controllers with a type other than Permanent, the least number of days left to expiration is shown.


Permanent—Licenses are node-locked and have no usage period associated with them. They are issued by the licensing portal of Cisco and must be installed using management interfaces on the device. Upon installation of these licenses, you have the necessary permissions across different versions.

Evaluation—Licenses are non-node-locked and are valid only for a limited period. They are used only when no permanent, extension, or grace period licenses exist. Before using an evaluation license, you must accept an End User License Agreement (EULA). Even though they are non-node-locked, their usage is recorded on the device. The number of days remaining on the evaluation license that has the fewest number of days until expiration is shown.

Extension—Licenses are node-locked and metered. They are issued by licensing portal of Cisco and must be installed using management interfaces on the device. Before using an extension license, you must accept a EULA during installation.

Grace Period—Licenses are node-locked and metered. These licenses are issued by licensing portal of Cisco as part of the permission ticket to rehost a license. They are installed on the device as part of the rehost operation, and you must accept a EULA as part of the rehost operation.

If you need to revoke a license from one controller and install it on another, it is called rehosting. You might want to rehost a license in order to change the purpose of a controller. See the Chapter 4, "Performing Maintenance Operations," of the Cisco Wireless LAN Controller Configuration Guide for information on rehosting a license.


Note The licensing status is updated periodically. To initiate an immediate update, choose Administration > Background Tasks and run the Controller License Status task.


If your network contains various Cisco licensed devices, you might want to consider using the Cisco License Manager (CLM) to manage all of the licenses using a single application. CLM is a secure client/server application that manages Cisco software licenses network wide. You can download the CLM software and access user documentation at this URL: http://www.cisco.com/go/clm. You can either register a PAK certificate with CLM or with the licensing portal found at https://tools.cisco.com/SWIFT/Licensing/PrivateRegistrationServlet.

WLC Controller License Summary

If you want to see more details about controller licensing, choose the Summary > Controller option from the left sidebar menu. The License Center page appears (see Figure 15-3). All currently active licenses on the controller are summarized.

Figure 15-3 License Center (Edit View) Page

All licensed controllers and their information in the bulleted list below are displayed. If you want to change how the controller results are displayed, click Edit View. In the Edit View page, highlight License Status, and click Hide to remove the column from the display.

Above the Controller Summary list is a series of filters that allow you to filter the list by Controller Name, Feature, Type, or Greater Than Percent Used. For example, if you enter 50, the list shows any WLCs that have more than 50% of its licenses used.


Note You can also use the Advanced Search link to sort the list of controllers.


Controller Name—Provides a link to the Files > Controller Files page.

Controller IP—The IP address of the controller.

Model—The controller model type.

Feature—The type of license, either Base or WPLUS. The Base license supports the standard software set, and the WPLUS license supports the premium Wireless Plus (WPLUS) software set. The WPLUS software set provides the standard feature set as well as added functionality for OfficeExtend access points, CAPWAP data encryptions, and enterprise wireless mesh.

AP Limit—The maximum capacity of access points allowed to join this controller.

AP Count—The current number of access points using licenses.

% Used—The percentage of licensed access points that are being used. If the percentage is greater than 75%, the bar appears red to indicate that the limit is being approached.

Type—The three different types of licenses are as follows:


Note For any controllers with a type other than Permanent, the least number of days left to expiration is shown.


Permanent—Licenses are node-locked and have no usage period associated with them. They are issued by licensing portal of Cisco and must be installed using management interfaces on the device. Upon installation of these licenses, you have the necessary permissions across different versions.

Evaluation—Licenses are non-node-locked and are valid only for a limited time period. They are used only when no permanent, extension, or grace period licenses exist. Before using an evaluation license, you must accept an End User License Agreement (EULA). Even though they are non-node-locked, their usage is recorded on the device. The number of days remaining on the evaluation license which has the fewest number of days until expiration is shown.

Extension—Licenses are node-locked and metered. They are issued by licensing portal of Cisco and must be installed using management interfaces on the device. Before using an extension license, you must accept a EULA during installation.


Note If a license shows as expired, the controller does not stop functioning. Only upon a reboot will the controller with the expired license become inactive.


Status—In Use, Not in Use, Inactive, or EULA Not Accepted.

Inactive—The license level is being used, but this license is not being used.

Not In Use—The license level is not being used and this license is not currently recognized.

Expired In Use—The license is being used, but is expired and will not be used upon next reboot.

Expired Not In Use—The license has expired and can no longer be used.

Count Consumed—The ap-count license is In Use.

Mobility Services Engine (MSE) License Information

There are three types of licenses:

Permanent—Licenses are node-locked and have no usage period associated with them. They are issued by licensing portal of Cisco and must be installed using management interfaces on the device. Upon installation of these licenses, you have the necessary permissions across different versions.

Evaluation—Licenses are non-node-locked and are valid only for a limited time period. They are used only when no permanent, extension, or grace period licenses exist. Before using an evaluation license, you must accept an End User License Agreement (EULA). Even though they are non-node-locked, their usage is recorded on the device. The number of days remaining on the evaluation license which has the fewest number of days until expiration is shown.

Extension—Licenses are node-locked and metered. They are issued by licensing portal of Cisco and must be installed using management interfaces on the device. Before using an extension license, you must accept a EULA during installation.

Major Polling—Specify two time periods at which you would want the major pollings to happen. Valid format: hh:mm AM|PM. Example: 12:49 AM.

For wired clients, NCS polls managed switches at regular interval to discover new clients or changes to the existing clients. To find this, NCS caches the last change time of the interface. In the next poll, it checks the new value of the change time of the interface with the cached value to determine whether there is any change on any interface. Then polling happens only for the interfaces where there is a change. If there is no change on an interface between the polling, no polling happens for that interface. When polling happens during major polling schedule, a complete polling is done irrespective of whether there is a change on the interface or not. The reason for having major and minor polling is because, polling the switches for wired clients on all interfaces is expensive and resource-intensive for NCS and switches. So, the major polling happens only twice a day.

Adding NCS to a Non-Cisco ACS Server for Use with RADIUS

When you use a RADIUS server to log into NCS, the AAA server sends back an access=accept message with a usergroup and a list of available tasks, after the username and password were verified. The access=accept message comes back as a fragmented packet because of the large number of tasks in some user groups. You can look in the following file to see the tasks associated with a given user group: C:\Program Files\NCS\webnms\webacs\WEB-INF\security\usergroup-map.xml. The tasks are passed back as a vendor specific attribute (VSA), and NCS requires authorization information using the VSA (IETF RADIUS attribute number 26). The VSA contains the NCS RADIUS task list information (see Figure 15-15).

Figure 15-15 Extracting Task List

The content of the VSA is as follows:

Type = 26 (IETF VSA number)

Vendor Id = 9 (Cisco vendor ID)

Vendor Type = 1 (Custom attributes)

Vendor Data = The NCS task information (for example NCS: task0 = Users and Group)

Each line from the NCS RADIUS task list should be sent in its own RADIUS VSA.

In the data portion of the access=access packet, the truncated output sometimes shows only one role sent back for an Admin user group login. The tasks associated with the role start with task0 and increment with task1, task2, and so on. Table 15-4 defines what these attributes in the access=access packet example signify.

Configuring an Audit

The Settings > Audit page allows you to determine the type of audit and on which parameters the audit is performed.

Audit Mode—Choose between basic auditing and template based auditing.

Audit On—Choose to audit on all parameters or on selected parameters for a global audit.

Audit Mode

The audit mode group box allows you to choose between basic auditing and template based auditing. Basic audit is selected by default.

Basic Audit—Audits the configuration objects in the NCS database against current WLC device values. Prior to the 5.1.0.0 version of NCS, this was the only audit mode available.


Note Configuration objects refer to the device configuration stored in the NCS database.


Template-based Audit—Audits on the applied templates, config group templates (which have been selected for the background audit), and configuration audits (for which corresponding templates do not exist) against current WLC device values.

To indicate the type of audit you want to perform, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Audit. The Audit Setting page appears (see Figure 15-20).

Figure 15-20 Audit Settings Page

Step 3 Select the Basic Audit or Template Based Audit. A basic audit audits the device configuration in the NCS database against the current WLC configuration. A template-based audit audits the applied templates, config group templates, and configuration objects (for which corresponding templates do not exist) against current WLC configuration.

Step 4 Choose if you want the audit to run on all parameters or only on selected parameters. If you select the Selected Parameters radio button, you can access the Configure Audit Parameters configuration page. (See the "Configuring Audit Parameters" section on page 15-79). The Select audit parameters URL appears.

The selected audit parameters are used during network and controller audits.

Step 5 Click Save.


Note These settings are in effect when the controller audit or network audit is performed.



Audit On

The Audit On group box allows you to audit on all parameters or to select specific parameters for an audit. When the Selected Parameters radio button is selected, you can access the Select Audit Parameters configuration page.

The selected audit parameters are used during network and controller audits.

Configuring Audit Parameters

To configure the audit parameters for a global audit, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Audit.

Step 3 Select the Selected Parameters radio button to display the Select Audit Parameters link.

Step 4 Click Save.

Step 5 Click Select Audit Parameters to choose the required parameters for the audit in the Audit Configuration > Parameter Selection page.

Step 6 Select the parameters that you want audited from each of the tabs. The tabs include System, WLAN, Security, Wireless, and Selected Attributes.

Step 7 When all desired audit parameters are selected, click Submit to confirm the parameters or click Cancel to close the page without saving any audit parameters.

Once you click Submit, the selected audit parameters display on the Selected Attributes tab.

A current Controller Audit Report can be accessed from the Configure > Controllers page by selecting an object from the Audit Status column.


Note You can audit a controller by choosing Audit Now from the Select a command drop-down list in the Configure > Controllers page, or by clicking Audit Now directly from the Controller Audit report. See the "Viewing Audit Status (for Access Points)" section on page 9-187.



Configuring Clients

You can configure the following client processes to improve NCS performance and scalability:

Processing Diagnostic Trap, page 15-80

Host Name Lookup, page 15-81

Data Retention, page 15-82

Client Traps and Syslogs, page 15-82

Autonomous Client Traps, page 15-82

To confirm changes to these client configurations, click Save at the bottom of the page.


Note See the "Client Troubleshooting Dashlet" section on page 10-4 for further information on client troubleshooting.


Processing Diagnostic Trap

The Settings > Client page allows you to enable automatic client troubleshooting on a diagnostic channel.


Note Automatic client troubleshooting is only available for a CCXV5 client.


To enable this automatic client troubleshooting, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Client. The Client page appears (see Figure 15-21).

Step 3 Select the Automatically troubleshoot client on diagnostic channel check box.


Note If the check box is selected, NCS processes the diagnostic association trap. If it is not selected, NCS raises the trap, but automated troubleshooting is not initiated.



Note While processing the diagnostic association trap, the NCS invokes a series of tests on the client. The client is updated on all completed tasks. The automated troubleshooting report is placed in dist/acs/win/webnms/logs. When the test is complete, the location of the log is updated in client details pages:V5 tab:Automated Troubleshooting Report group box. An export button allows you to export the logs.


Step 4 Click Save.


Host Name Lookup

DNS lookup can take a considerable amount of time. Because of this, you can enable or disable the DNS lookup for client host name. It is set to Disable by default.

To enable host name lookup, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Client.

Step 3 Select the Lookup client host names from DNS server check box.

Step 4 Enter the number of days that you want the host name to remain in the cache.

Step 5 Click Save.


Data Retention

Client association history can take a lot of database and disk space. This can be an issue for database backup and restore functions. The retaining duration of a client association history can be configured to help manage this potential issue.

To configure data retention parameters, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Client.

Step 3 Enter or edit the following data retention parameters:

Dissociated Clients (days)—Enter the number of days that you want NCS to retain the data. The default is 7 days. The valid range is 1 to 30 days.

Client session history (days)—Enter the number of days that you want NCS to retain the data. The default is 32 days. The valid range is 7 to 365 days.

Step 4 Click Save.


Client Discovery

If you select the Poll clients when client traps/syslogs received check box, NCS polls clients to quickly identify client sessions. In a busy network, you may want to disable polling while the client traps are received. This option is disabled by default.

Client Traps and Syslogs

In some deployments, NCS may receive large amounts of client association and disassociation traps. Saving these traps as events may cause a slight performance issue. In such cases, other events that may be useful may be aged out sooner than expected.

To ensure that NCS does not save client association and disassociation traps as events, unselect the Save client association and disassociation traps as events check box. Click Save to confirm this configuration change. This option is disabled by default.

For more information on traps and syslogs, see Enabling Traps and Syslogs on Switches for Wired Client Discovery, page 9-198.

Autonomous Client Traps

Select the Save 802.1x and 802.11 client authentication fail traps as events option if you want to save the Save 802.1x and 802.11 client authentication failed traps as events.

Interval Time—Enter the time interval in seconds to poll for the failed traps.

Configuring Protocols for CLI Sessions

Many NCS features such as autonomous access point and controller CLI templates, along with migration templates require executing CLI commands on the autonomous access point or controller. These CLI commands can be executed by establishing Telnet or SSH sessions. The CLI session page allows you to select the session protocol. SSH is the default.


Note In CLI templates, you are not required to answer the question responses (such as Yes or No answer to a command, Press enter to continue, and so on.). This is automatically performed by NCS.


To configure the protocols for CLI sessions, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose CLI Session.

Step 3 The default controller session protocol SSH is selected. To choose Telnet, select that radio button.

Step 4 The default autonomous access point session protocol SSH is selected. To choose Telnet, select the radio button.

Step 5 The Run Autonomous AP Migration Analysis on discovery option is set to No by default. Choose Yes if you want to discover the autonomous APs as well as perform migration analysis.

Step 6 Click Save.


Configuring Controller Upgrade

The Controller Upgrade Settings page allows you to auto-refresh after a controller upgrade. To perform an auto-refresh, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Controller Upgrade Settings (see Figure 15-22).

Figure 15-22 Controller Upgrade Settings

Step 3 Select the Auto refresh After Upgrade check box to automatically restore the configuration whenever there is a change in the WLC image.

Step 4 Determine the action NCS will take when a save config trap is received. When this option is enabled, you can choose to retain or delete the extra configurations present on the device but not on NCS. The setting is applied to all controllers managed by NCS.


Note If you select the Auto Refresh on Save Config Trap check box in the Configure > Controllers > Properties > Settings page, it overrides this global setting.



Note It may take up to three minutes for the automatic refresh to occur.


Step 5 Click Save.

Whenever a save config trap is received by NCS this option when enabled will determine the action taken by NCS.

When this option is enabled user can choose to retain or delete the extra configurations present on device and not on NCS.

This setting will be applied to all of the controllers managed by NCS. The setting in the controller > properties page for processing the save config trap will override this global setting.

When there is a change in the WLC image, the configuration from the controller is automatically restored.


Configuring Data Management

To set retention periods for aggregated data used in timed calculations and network audit calculations, follow these steps. You can configure retention periods on an hourly, daily, and weekly basis.


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Data Management. The Data Management page appears (see Figure 15-23).

Figure 15-23 Data Management Page

Step 3 Specify the number of days to keep the hourly data. The valid range is 1 to 31. The default is 31 days.

Step 4 Specify the number of days to keep the daily data. The valid range is 7 to 365. The default is 90 days.

Step 5 Specify the number of weeks to keep the weekly data. The valid range is 2 to 108. The default is 54 weeks.

Step 6 Specify the number of days to retain the audit data collected by the Network Audit background task before purging. The limit is 365 days, and the minimum cleanup interval is 7 days. The default is 90 days.


Note For the best interactive graph data views, change the default settings to the maximum possible: 90 days for daily aggregated data and 54 weeks for weekly aggregated data. You must also make the appropriate measures to increase RAM and CPU capacity to compensate for these adjustments.


Step 7 Click Save.


NCS Historical Data

There are two types of historical data in NCS, including the following:

Aggregated historical data—Numeric data that can be gathered as a whole and aggregated to minimum, maximum, or average. Client count is one example of aggregated historical data.

Use the Administration > Settings > Data Management page to define the aggregated data retention period. Aggregation types include hourly, daily, and weekly.

The retention period for these aggregation types are defined as Default, Minimum, and Maximum (see Table 15-5).

Table 15-5 Aggregated Data Retention Periods

Aggregated Data
Default
Minimum
Maximum

Hourly

31 days

1 day

Step 5 Provide the same information for the secondary SMTP server (only if a secondary mail server is available).

Step 6 The From text box in the Sender and Receivers portion of the page is populated with NCS@<NCS server IP address>. You can change it to a different sender.

Step 7 Enter the e-mail addresses of the recipient in the To text box. The e-mail address you provide serves as the default value for other functional areas, such as alarms or reports. Multiple e-mail addresses can be added and should be separated by commas.


Note Global changes you make to the recipient e-mail addresses in Step 7 are disregarded if e-mail notifications were set.


You must indicate the primary SMTP mail server and fill the From address text boxes.

If you want all alarm categories applied to the provided recipient list, select the Apply recipient list to all alarm categories check box.

Step 8 Enter the text that you want to append to the email subject.

Step 9 If you click the Configure email notification for individual alarm categories link, you can specify the alarm categories and severity levels you want to enable. Email notifications are sent when an alarm occurs that matches categories and the severity levels you select.


Note You can set each alarm severity by clicking the alarm category, choosing Critical, Major, Minor, or Warning, and providing an email address.


Step 10 Click the Test button to send a test e-mail using the parameters you configured. The results of the test operation appear on the same screen. The test feature checks the connectivity to both primary and secondary mail servers by sending an e-mail with a "NCS test e-mail" subject line.

If the test results were satisfactory, click Save.

Step 3 To view or edit details about a current SNMP entry, click the Network Address link. See the "Viewing Current SNMP Credential Details" section on page 15-99 for more information.


Note The default network address is 0.0.0.0 which indicates the entire network. An SNMP credential is defined per network so only network addresses are allowed. 0.0.0.0 is the SNMP credential default and is used when no specific SNMP credential is defined. The default community string is private for both read and write. You should update the pre-populated SNMP credential with your own SNMP information.


Figure 15-33 SNMP Credentials Page

Step 4 To add a new SNMP entry, choose Add SNMP Entries from the Select a command drop-down list and click Go. See the "Adding a New SNMP Credential Entry" section on page 15-100 for more information.


Viewing Current SNMP Credential Details

To view or edit details for current SNMP credentials, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose SNMP Credentials.

Step 3 Click the Network Address link to open the SNMP Credential Details page. The details page displays the following information:

General Parameters

Add Format Type—Read-only. See the "Adding a New SNMP Credential Entry" section on page 15-100 for more information regarding Add Format Type.

Network Address

Network Mask

SNMP Parameters—Select the applicable version(s) for SNMP parameters. The SNMP credentials are validated according to which SNMP version(s) are selected.


Note Enter SNMP parameters for write access, if available. With read-only access parameters, the switch is added but you will not be able to modify its configuration in NCS. Device connectivity tests use the SNMP retries and timeout parameters configured in Administration > Settings > SNMP Settings.


Retries—The number of times that attempts are made to discover the switch.

Timeout—The session timeout value in seconds. This determines the maximum amount of time allowed for a client before it is forced to reauthenticate.

SNMP v1 Parameters or v2 Parameters—If selected, enter the applicable community in the available text box.

SNMP v3 Parameters—If selected, configure the following parameters:

Username

Auth. Type

Auth. Password

Privacy Type

Privacy Password


Note If SNMP v1 or v2 with default community is configured, the network is open to easy attacks because default communities are well known. SNMP v1 or v2 with a non-default community is more secure than a default community, but SNMP v3 with Auth and Privacy type and no default user is the most secure SNMP connection.


Step 4 Click OK to save changes or Cancel to return to the SNMP Credentials page without making any changes to the SNMP credential details.


Adding a New SNMP Credential Entry

To add a new SNMP credential entry, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose SNMP Credentials.

Step 3 From the Select a command drop-down list, choose Add SNMP Entries.

Step 4 Click Go. The SNMP Credentials page opens (see Figure 15-33).

Step 5 Choose one of the following:

To manually enter SNMP credential information, leave the Add Format Type drop-down list at SNMP Credential Info. To add multiple network addresses, use a comma between each address. Go to Step 7.

If you want to add multiple switches by importing a CSV file, choose File from the Add Format Type drop-down list. The CSV file allows you to generate your own import file and add the devices you want. Go to Step 6.

Step 6 If you chose File, click Browse to find the location of the CSV file you want to import. Skip to Step 11.

The first row of the CSV file is used to describe the columns included. The IP Address column is mandatory.

Sample File:

ip_address,snmp_version,snmp_community,snmpv3_user_name,snmpv3_auth_type,snmpv3_auth_passw
ord,snmpv3_privacy_type,snmpv3_privacy_password,network_mask  
1.1.1.0,v2,private,user1,HMAC-MD5,12345,DES,12345,255.255.255.0  
2.2.2.0,v2,private,user1,HMAC-MD5,password3,DES,password4,255.255.255.0  
10.77.246.0,v2,private,user1,HMAC-MD5,12345,DES,12345,255.255.255.0 

The CSV file can contain the following fields:

ip_address:IP address

snmp_version:SNMP version

network_mask:Network mask

snmp_community:SNMP V1/V2 community

snmpv3_user_name:SNMP V3 username

snmpv3_auth_type:SNMP V3 authorization type. Can be None or HMAC-MD5 or HMAC-SHA

snmpv3_auth_password:SNMP V3 authorization password

snmpv3_privacy_type:SNMP V3 privacy type. Can be None or DES or CFB-AES-128

snmpv3_privacy_password:SNMP V3 privacy password

snmp_retries:SNMP retries

snmp_timeout:SNMP timeout

Step 7 If you chose SNMP Credential Info, enter the IP address of the switch you want to add. If you want to add multiple switches, use a comma between the string of IP addresses.

Step 8 In the Retries parameter, enter the number of times that attempts are made to discover the switch.

Step 9 Provide the session timeout value in seconds. This determines the maximum amount of time allowed for a client before it is forced to reauthenticate.

Step 10 Select the applicable version(s) for SNMP parameters. The SNMP credentials are validated according to which SNMP version(s) are selected.

If SNMP v1 Parameters or v2 Parameters is selected, enter the applicable community in the available text box.

If SNMP v3 Parameters is selected, configure the following parameters:

Username

Auth. Type

Auth. Password

Privacy Type

Privacy Password


Note If SNMP v1 or v2 with default community is configured, the network is open to easy attacks because default communities are well known. SNMP v1 or v2 with a non-default community is more secure than a default community, but SNMP v3 with Auth and Privacy type and no default user is the most secure SNMP connection.


Step 11 Click OK.

If NCS can use the SNMP credential listed to access the switch, the switch is added for later use and will appear in the Configure > Ethernet Switches page.


Note If you manually added switches through the Configure > Ethernet Switches page, then switch port tracing will use the credentials from that page, not the ones listed in the SNMP Credentials page. If the manually-added switch credentials have changed, you need to update them from the Configure > Ethernet page.



Configuring SNMP Settings

The SNMP Settings page allows you to configure global SNMP settings from NCS.


Note Any changes you make on this screen globally effect NCS. The changes are saved across restarts as well as across backups and restores.


To configure global SNMP settings, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose SNMP Settings. The SNMP Settings page appears (see Figure 15-34).

Figure 15-34 SNMP Settings Page

Step 3 If the Trace Display Values check box is selected, mediation trace-level logging shows data values fetched from the controller using SNMP. If unselected, the values do not appear.


Note The default is unselected for security reasons.


Step 4 For the Backoff Algorithm, choose either Exponential or Constant Timeout from the drop-down list. If you choose Exponential (the default value), each SNMP try waits twice as long as the previous try, starting with the specified timeout for the first try. If you choose Constant Timeout, each SNMP try waits the same, specified amount of time.


Note Constant Timeout is useful on unreliable networks (such as satellite networks) where the desired number of retries is large. Because it does not double the timeout per try, it does not take as long to timeout with a high number of retries.


Step 5 Determine if you want to use reachability parameters. If selected, the NCS defaults to the global Reachability Retries and Timeout that you configure. If unselected, NCS always uses the timeout and retries specified per-controller or per-IOS access point. The default is selected.


Note Adjust this setting downward if switch port tracing is taking a long time to complete.


Step 6 For the Reachability Retries parameter, enter the number of global retries used for determining device reachability. The default number is 2. This parameter is only available if the Use Reachability Parameters check box is selected.


Note Adjust this setting downward if switch port tracing is taking a long time to complete.


Step 7 For the Reachability Timeout parameter, enter a global timeout used for determining device reachability. The default number is 2. This parameter is only available if the Use Reachability Parameters check box is selected.

Step 8 At the Maximum VarBinds per PDU parameter, enter a number to indicate the largest number of SNMP variable bindings allowed in a request or response PDU. The default is 100.


Note For customers who have issues with PDU fragmentation in their network, this number can be reduced to 50, which typically eliminates the fragmentation.


Step 9 The maximum rows per table parameter is configurable and the default value is 50000 rows. The configured value is retained even if you upgrade the NCS version.

Step 10 Click Save to confirm these settings.


Configuring Switch Port Tracing

Currently, NCS provides rogue access point detection by retrieving information from the controller. The rogue access point table is populated with any detected BSSID addresses from any frames that are not present in the neighbor list. At the end of a specified interval, the contents of the rogue table are sent to the controller in a CAPWAP Rogue AP Report message. With this method, NCS would simply gather the information received from the controllers; but with software release 5.1, you can now incorporate switch port tracing of Wired Rogue Access Point Switch Ports. This enhancement allows you to react to found wired rogue access points and prevent future attacks. The trace information is available only in the NCS log and only for rogue access points, not rogue clients.


Note Rogue Client connected to the Rogue Access point information is used to track the switch port to which the Rogue Access point is connected in the network.



Note If you try to set tracing for a friendly or deleted rogue, a warning message appears.



Note For Switch Port Tracing to successfully trace the switch ports using and v3, all of the OIDs should be included in the SNMP v3 view and VLAN content should be created for each VLAN in the SNMP v3 group.



Note See the "Configuring Switch Port Tracing" section on page 15-103 for information on configuring Switch Port Tracing settings.


The Switch Port Trace page allows you to run a trace on detected rogue access points on the wire.

To correctly trace and contain rogue access points, you must correctly provide the following information.

Reporting APs—A rogue access point has to be reported by one or more managed access points.

AP CDP Neighbor—Access point CDP neighbor information is required to determine the seed switches.

Switch IP address and SNMP credentials—All switches to be traced must have a management IP address and SNMP management enabled. You can add network address based entries instead of only adding individual switches. The correct write community string must be specified to enable/disable switch ports. For tracing, read community strings are sufficient.

Switch port configuration—Trunking switch ports must be correctly configured. Switch port security must be turned off.

Only Cisco Ethernet switches are supported.

Switch VLAN settings must be properly configured.

CDP protocol must be enabled on all switches.

An Ethernet connection must exist between the rogue access point and the Cisco switch.

You should have some traffic between rogue access points and the Ethernet switch.

The rogue access point must be connected to a switch within the max hop limit. The default hop count is 2, and the maximum is 10.

If SNMPv3 is chosen, use the context option and create one for each VLAN, in addition to the one for the main group (which is required for non-VLAN-based MIBs).

To specify options for switch port tracing, follow these steps:


Step 1 Choose Administration > Settings.

Step 2 From the left sidebar menu, choose Switch Port Trace (see Figure 15-35).

Figure 15-35 Switch Port Trace Page

Step 3 Configure the following basic settings as needed:

MAC address +1/-1 search—Select the check box to enable.

This search involves the MAC address +1/-1 convention where the wired-side MAC address of the rogue access point is obtained by adding or subtracting the radio MAC address by one.

Rogue client MAC address search—Select the check box to enable.

When a rogue access point client exists, the MAC address of the client is added to the searchable MAC address list.

Vendor (OUI) search—Select the check box to enable. OUI refers to Organizational Unique Identifier search which searches the first 3 bytes in a MAC address.

Exclude switch trunk ports—Select the check box to exclude switch trunk ports from the switch port trace.


Note When more than one port is traced for a given MAC address, additional checks are performed to improve accuracy. These checks include: trunk port, non-AP CDP neighbors present on the port, and whether or not the MAC address is the only one on this port.


Exclude device list—Select the check box to exclude additional devices from the trace. Enter into the device list text box each device that you want to exclude from the switch port trace. Separate each device names with commas.

Max hop count—Enter the maximum number of hops for this trace. Keep in mind that the greater the hop count, the longer the switch port trace will take to perform.

Exclude vendor list—Enter in the vendor list text box any vendors that you want to exclude from the switch port trace. Separate vendor names with commas. The vendor list is not case sensitive.

Step 4 Configure the following advanced settings as needed:

TraceRogueAP task max thread—Switch port tracing uses multiple threads to trace rogue access points. This field indicates the maximum number of rogue access points that can be traced on parallel threads.

TraceRogueAP max queue size—Switch port tracing maintains a queue to trace rogue access points. Whenever you select a rogue access point for tracing, it is queued for processing. This field indicates the maximum number of entries that you can store in the queue.

SwitchTask max thread—Switch port tracing uses multiple threads to query switch devices. This field indicates the maximum number of switch devices that you can query on parallel threads.


Note The default value for these parameters should be good for normal operations. These parameters directly impact the performance of switch port tracing and NCS. Unless required, We do not recommend that you alter these parameters.


Select CDP device capabilities—Select the check box to enable.


Note NCS uses CDP to discover neighbors during tracing. When the neighbors are verified, NCS uses the CDP capabilities field to determine whether or not the neighbor device is a valid switch. If the neighbor device is not a valid switch, it is not traced.


Step 5 Click Save to confirm changes made. Click Reset to return the page to the original settings. Click Factory Reset to return settings to the factory defaults.


Establishing Switch Port Tracing

To establish switch port tracing, follow these steps:


Step 1 In the NCS home page, click the Security dashboard.

Step 2 In the Rogue APs and Adhoc Rogues section, click the number URL which specifies the number of rogues in the last hour, last 24 hours, or total active.

Step 3 Choose for which rogue you are setting switch port tracking by clicking the URL in the MAC Address column. The Alarms > Rogue AP details page opens.

Step 4 From the Select a command drop-down list, choose Trace Switch Port. The Trace Switch Port page opens and NCS runs a switch port trace.

When one or more searchable MAC addresses are available, the NCS uses CDP to discover any switches connected up to two hops away from the detecting access point. The MIBs of each CDP discovered switch is examined to see if it contains any of the target MAC addresses. If any of the MAC addresses are found, the corresponding port number is returned and reported as the rogue switch port.

The SNMP communities for the switches are provided in the "Configuring Switches" section on page 9-190.

See the "Switch Port Tracing Details" section on page 15-107 for additional information on the Switch Port Tracing Details dialog box.


Switch Port Tracing Details

In the Switch Port Tracing Details dialog box, you can enable or disable switch ports, trace switch ports, and view detail status of the access point switch trace. For more information on Switch Port Tracing, see the following topics:

Configuring Switch Port Tracing—Provides information on configuring switch port trace settings.

Configuring Switches—Provides information on configuring SNMP switches.

Configuring SNMP Credentials—Provides information on configuring SNMP switch credentials.

In the Switch Port tracing Details dialog box, do one of the following:

Click Enable/Disable Switch Port(s)—Enables or disables any selected ports.

Click Trace Switch Port(s)—Runs another switch port trace.

Click Show Detail Status—Displays details regarding the switch port traces for this access point.

Click Close.

Switch Port Tracing Troubleshooting

Switch Port Tracing (SPT) works on a best-effort-basis. SPT depends on the following information to correctly trace and contain rogue APs:

Reporting access points—A rogue access point must be reported by one or more managed access points.

Access point CDP neighbor—Access point CDP neighbor information is required to determine the seed switches.

Switch IP address and SNMP credentials

All the switches that need to be traced should have a management IP address and SNMP management enabled.

With the new SNMP credential changes, instead of adding the individual switches to NCS, network address based entries can be added.

The new SNMP credential feature will have a default entry 0.0.0.0 with default community string as 'private' for both read/write.

Correct write community string has to be specified to enable/disable switch ports. For tracing, read community string should be sufficient.

Switch port configuration

Switch ports that are trunking should be correctly configured as trunk ports.

Switch port security should be turned off.

Only Cisco Ethernet switches are supported.


Note The following switches are supported: 3750, 3560, 3750E, 3560E, and 2960.


Switch VLAN settings should be properly configured.

CDP protocol should be enabled all the switches.

An Ethernet connection should exist between the rogue access point and the Cisco switch.

There should be some traffic between the rogue access point and the Ethernet switch.

The rogue access point should be connected to a switch within the max hop limit. Default hop is 2. Max hop is 10.

If SNMPv3 is used, then make sure you use the context option and create one for each VLAN in addition to the one for the main group (which is required for non-VLAN based MIBs).

Configuring High Availability

This section contains the following topics:

Guidelines and Limitations for High Availability, page 15-109

Failover Scenario, page 15-109

High Availability Status, page 15-110

Configuring High Availability on the Primary NCS, page 15-110

Deploying High Availability, page 15-112

Adding a New Primary NCS, page 15-113

Removing a Primary NCS, page 15-113

Guidelines and Limitations for High Availability

Before initiating failover, you must consider the following prerequisites and limitations:

You must have the extra hardware identical to the primary NCS to run a stand-by instance of NCS.

NCS supports High Availability on both the physical and virtual appliance deployment models.

A reliable high-speed wired network must exist between the primary NCS and its backup NCS.

The primary and secondary NCS must be running the same NCS software release.

For primary NCS to initiate High Availability with secondary NCS, the status of the secondary NCS services must be running and reachable from the primary NCS. So, you must boot the secondary NCS first and then boot the primary NCS to initiate the High Availability registration.

Failover should be considered temporary. The failed primary NCS should be restored to normal as soon as possible, and failback will be re-initiated. The longer it takes to restore the failed primary NCS, the longer the other NCSs sharing that secondary NCS must run without failover support.

The latest controller software must be used.

The primary and secondary host are not required to share the same subnet. They can be geographically separated.

If a secondary host fails for any reason, all the primary instances are affected, and they run in stand-alone mode without any failover support.

The ports over which the primary and secondary NCSs communicate must be open (not blocked with network firewalls, application fireways, gateways, and so on). The tomcat port is configurable during installation, and its default port is 8082. You should reserve solid database ports from 1315 to 1319.

Any access control lists imposed between the primary and secondary NCS must allow traffic to go between the primary and secondary NCSs.

In a 2:1 high availability scenario, the secondary NCS must be a high-end PC with more memory than the two primary PCs.

The primary Prime Infrastructure must have sufficient number of licenses for the devices. When the failover occurs the secondary Prime Infrastructure uses the licenses of the primary Prime Infrastructure for the devices.

NCS 1.0 updates to High Availability

In NCS 1.0 release, a secondary NCS can only support one primary NCS.

When High Availability is enabled for the first time, the sync up of the servers will take a considerable amount of time. The time it would take would be in the order of 30 minutes or more depending on the size of the database.

Failover Scenario

When a failure of a primary NCS is automatically detected, the following events take place:


Note One physical secondary NCS can back many primary devices (NCS).


1. The primary NCS is confirmed as non-functioning (hardware crash, network crash, or the like) by the health monitor on the secondary NCS.

2. If automatic failover has been enabled, NCS is started on the secondary as described in Step 3. If automatic failover is disabled, an email is sent to the administrator asking if they want to manually start failover.

3. The secondary NCS instance is started immediately (using the configuration already in place) and uses the corresponding database of the primary. After a successful failover, the client should point to the newly activated NCS (the secondary NCS). The secondary NCS updates all controllers with its own address as the trap destination.


Note The redirecting of web traffic to the secondary NCS does not occur automatically. You must use your infrastructure tools to properly configure this redirection.


4. The result of the failover operation is indicated as an event in the Health Monitor UI, or a critical alarm is sent to the administrator and to other NCS instances.

High Availability Status

To view High Availability details, follow these steps:


Step 1 Choose Administration > High Availability.

Step 2 Choose HA Status from the left sidebar menu. The following information is displayed:

Current status

Time, state, and description of each event


Configuring High Availability on the Primary NCS


Note When database transaction logs grow to 1/3 of the database partition disk space, set the database to "Standalone" mode to prevent transaction logs from keep growing. But it requires a complete netcopy next time when the database synchronization occurs.


Follow these steps to configure high availability on the primary NCS. You must specify the NCS role (either standalone, primary, or secondary) during installation. See the "Deploying the NCS Virtual Appliance" section on page 2-5 to see the installation steps.


NoteBefore you configure high availability, you must configure a mail server. See the "Configuring the Mail Server" section on page 15-87 for steps on configuring a mail server.

If you specify an e-mail address in the HA Configuration page then ensure a mail server is configured and reachable.


Step 1 Choose Administration > High Availability.

Step 2 Choose HA Configuration from the left sidebar menu. The High Availability Configuration page appears (see Figure 15-36).

Figure 15-36 High Availability Configuration Page

The current status of high availability is shown in the upper portion of the page.

Step 3 Enter the IP address or hostname of the secondary NCS.

Step 4 Enter the authentication key specified during the installation of the secondary NCS.

Step 5 The default admin e-mail address that you configured in Administration > Settings > Email Server is automatically supplied. You can make any necessary changes. Any changes you make to these email addresses must also be entered in the Secondary SMTP Server section of the Administration > Settings > Mail Server page.


Note You must enter an email address when configuring high availability. NCS tests the email server configuration, and if the test fails (because the mail server cannot connect), NCS does not allow the high availability configuration.


Step 6 Choose either a manual or automatic failover option. If you choose manual, you can trigger the failover operation with a button in the secondary HealthMonitor GUI or with the URL specified in the email which the administrator receives upon failure of the primary NCS. If you choose automatic, the secondary NCS initiates a failover on its own when a failure is detected on the primary.

Step 7 If you have installed NCS 1.0, then click Save Only to retain the configuration but not enable high availability at the current time, or click Save & Enable to enable high availability.


Note You can configure the high availability feature now but enable it at a later time.


Or

If you have installed NCS 1.0.2.x, then click Save to retain the configuration and enable high availability, or click Remove to disable high availability and its settings.


Note The Remove button is only available if high availability is already configured.


At this point, the secondary is either reachable with the database, and files are synchronized between health monitors, or the secondary is unreachable, and an error is returned because secondary installation did not occur.


From the NCS GUI (Administration > High Availability) after high availability has been enabled, you can perform the following functions:

Update—Use the Update function to make changes to the Report Repository path (Administration > Settings > Report) or FTP/TFTP root directory (Administration > Settings > Server Settings) and to appropriately synchronize the files.

Disable—Use the Disable function to break the connection between the primary and secondary NCSs. The database and files stop synchronizing.

This check box is not available in NCS Release 1.0.2.x.

Delete—Use the Delete operation to decommission the primary NCS from the secondary NCS.

The Delete button is replaced by Remove in NCS Release 1.0.2.x.

Cancel—Use the Cancel operation to cancel any modifications you made to the high availability configuration. You are returned to the High Availability Status page after you choose Cancel.

Deploying High Availability

To deploy high availability on an existing NCS installation, follow these steps:


Step 1 Identify and prepare the hardware to run the secondary NCS.

Step 2 Ensure that network connectivity between the primary and secondary NCS is functioning, and all necessary ports are open.

Step 3 Install the secondary NCS with the same version of NCS that is installed on the primary. See the "Deploying the NCS Virtual Appliance" section on page 2-5.

Step 4 Start the secondary NCS as a standby server. In this mode, the NCS application does not start. At the same time, the Health Monitor is started on the secondary NCS.

Step 5 On every primary NCS that needs to use this secondary NCS, stop the NCS.

Step 6 On the primary host, install the new version of NCS and perform all necessary upgrade steps.

Step 7 Start the primary NCS (as a primary). The Health Monitor also starts.

Step 8 Configure the high availability parameters described in the "Configuring High Availability on the Primary NCS" section on page 15-110.

Step 9 Click Activate to activate high availability on the primary. NCS primary first copies its database to the secondary NCS and then connects to the secondary. The following files are copied over from the primary to the secondary NCS:

DB password file

all auto provisioning startup config files

all domain maps

all history reports which are generated by scheduled report tasks

High availability deployment is complete. Use https://<wcsip>:8082 to access the HealthMonitor UI. Within the HealthMonitor UI, use the authentication key to login.

You can change the authentication key in WCS using the command prompt. To change the authentication key, change the path to WCS installation directory then to "bin" and enter hmadmin - authkey key.

To view the current status of the health monitor, enter hmadmin [-options] status.


Adding a New Primary NCS

Follow these steps to add a new primary NCS to an existing setup. This new primary NCS uses the existing secondary as the failover server.


Step 1 Ensure that network connectivity between the new primary and secondary is functioning and that all necessary ports are open.

Step 2 Make sure that the same NCS release that is loaded on the other primary NCS and secondary NCS is loaded on the new primary NCS.

Step 3 Install the correct version of NCS on the primary NCS.

Step 4 Upgrade the primary NCS. The Health Monitor also starts.

Step 5 Follow the steps in the "Configuring High Availability" section on page 15-108.

Step 6 After the primary NCS connects to the secondary, the Health Monitor on the primary connects to the secondary Health Monitor. They mutually acknowledge each other and start the monitoring.

High availability deployment is now complete.


Removing a Primary NCS

When a primary NCS instance is removed from a group, you must disable the peer database instance on the secondary NCS and remove the Health Monitor for that primary. (To remove the primary NCS from high availability, use the Remove button on the High Availability configuration page.) The secondary NCS disables the database instance and removes the uninstalled primary NCS from its Health Monitor.

Setting User Preferences

This page contains user-specific settings you may want to adjust.

To change the user-specific settings, follow these steps:


Step 1 Choose Administration > User Preferences. The User Preferences Page appears (see Figure 15-37).

Figure 15-37 User Preferences Page

Step 2 Use the Items Per List Page drop-down list to configure the number of entries shown on a given list page (such as alarms, events, AP list, and so on.).

Step 3 Specify how often you want the home page refreshed by selecting the Refresh home page check box and choosing a time interval from the Refresh home page every drop-down list.

Step 4 Select the Logout idle user check box and configure the Logout idle user after text box, in minutes, that a user session can be idle before the server cancels the session.

Step 5 If you want the maps and alarms page to automatically refresh when a new alarm is raised by NCS, select the Refresh Map/Alarms page on new alarm check box in the Alarms portion of the page.

Step 6 From the Refresh Alarm count in the Alarm Summary every drop-down list choose a time interval to to specify how often to reset.

Step 7 If you do not want the alarm acknowledge warning message to appear, select the Disable Alarm Acknowledge Warning Message check box.

Step 8 Use the Edit Alarm Categories to select the alarm categories to display in the Alarm Summary page.

Step 9 In the Select Alarms page, choose the default category to display from the drop-down list, and select the alarm categories and sub categories to display from the alarm toolbar. Click Save to save the alarm category list. The selected alarm category and sub categories appears in the User Preferences page.

Step 10 Click Save to save the User Preference settings.

Note NCS does not directly manage controller licenses. It simply monitors the licenses. You can manage the licenses using CLI, WebUI, or Cisco License Manager (CM) at the following URL:

https://tools.cisco.com/SWIFT/Licensing/PrivateRegistrationServlet
.


The page displays the following information:

Controller Name

Controller IP

Feature—The feature options are wplus-ap-count, wplus, base-ap-count, and base. Two are active at any one time for an enable feature level of WPLUS or Base and the AP count (base-ap-count or wplus-ap-count), which determines the number of access points that the controller supports (12, 25, 50, 100, or 250). For every physical license installed, two license files show up in the controller as a feature level license and an ap-count license. For example, if you install a WPlus 500 license on the controller, you see a wplus or wplus-ap-count feature.


Note You can have both a WPLUS and Base license, but only one can be active at a time.


AP Limit—The number of access points that the controller supports.

EULA Status—Whether the End User License Agreement has been accepted or not.

Comments—Any user-entered comments about the license when it is installed.

Type—Permanent, evaluation, or extension.


Note For any controllers with a type other than Permanent, the number of days left to expiration is shown. A license is not in use does not incur the reduction in count until it is in use.


Status —The status can be described as follows:

Inactive—The license level is being used, but this license is not in use.

Not In Use—The license level is not being used, and this license is currently unrecognized.

Expired in Use—The license is being used, but it is expired and will not be used upon next reboot.

Expired Not in Use—The license has expired and can no longer be used.

Count Consumed—The ap-count license is In Use.

All licensed controllers and their information are displayed. If you want to change how the controller results are displayed, click Edit View. In the Edit View page, use the Show and Hide buttons to determine how the columns appear.

Above the Controller Summary list is a series of filters that allow you to sort the list by Controller Name, Feature, or Type.

This page displays the following parameters:

Controller Name

Controller IP—The IP address of the controller.

Feature—License features include wplus-ap-count, wplus, base-ap-count, and base.

For every physical license installed, two license files display in the controller: a feature level license and an ap-count license. For example if you install a "WPlus 500" license on the controller, "wplus" and "wplus-ap-count" features display. There are always two of these features active at any one time that combine to enable the feature level (WPlus or Base) and the AP count.


Note You can have both a WPlus and Base license, but only one can be active at any given time.


AP Limit—The maximum capacity of access points allowed to join this controller.

EULA status—Displays the status of the End User License Agreement and is either Accepted or Not Accepted.

Comments—User entered comments when the license is installed.

Type—The four different types of licenses are as follows:

Permanent—Licenses are node locked and have no usage period associated with them. They are issued by Cisco licensing portal and must be installed using management interfaces on the device. Upon installation of these licenses, you have the necessary permissions across different versions.

Evaluation—Licenses are non-node locked and are valid only for a limited time period. They are used only when no permanent, extension, or grace period licenses exist. Before using an evaluation license, you must accept an End User License Agreement (EULA). Even though they are non-node locked, their usage is recorded on the device. The number of days left displays for the evaluation license with the fewest number of remaining active license days.

Extension—Licenses are node locked and metered. They are issued by Cisco licensing portal and must be installed using management interfaces on the device. Before using an extension license, you must accept a EULA during installation.

Grace Period—Licenses are node locked and metered. These licenses are issued by Cisco licensing portal as part of the permission ticket to rehost a license. They are installed on the device as part of the rehost operation, and you must accept a EULA as part of the rehost operation.


Note Types other than Permanent display the number of days left until the license expires. Licenses not currently in use do not have their counts reduced until they become "In Use".


Status

In Use—The license level and the license are in use.

Inactive—The license level is being used, but this license is not being used.

Not In Use—The license level is not being used and this license is not currently recognized.

Expired In Use—The license is being used, but is expired and will not be used upon next reboot.

Expired Not In Use—The license has expired and can no longer be used.

Count Consumed—The ap-count license is In Use.


Note If you need to filter the list of license files, you can enter a controller name, feature, or type and click Go.

This page displays a list of users currently logged in. The user highlighted in red represents your current login.


Note You must be logged into a user account with SuperUsers privileges to see active sessions.


If a column heading is a hyperlink, click the heading to sort the list of active sessions in descending or ascending order along that column. The sort direction is toggled each time the hyperlink is clicked.

The Active Sessions page has the following columns:

Username—The User ID of the User who is logged in.

IP/Host Name—The IP address or the hostname of the machine on which the browser is running. If the hostname of the user machine is not in DNS, the IP address is displayed.

Login Time—The time at which the user logged in to NCS. All times are based on the NCS server machine time.

Last Access Time—The time at which the user browser accessed NCS. All times are based on the NCS server machine time.


Note The time displayed in this column is usually a few seconds behind the current system time because Last Access Time is updated frequently by the updates to the alarm status panel. However, if a user navigates to a non NCS web page in the same browser, the disparity in time will be greater. Alarm counts are not updated when the browser is not displaying NCS web pages.


Login Method—The login method can be either of the following:

Local

Radius

TACACS+

User Groups—The list of groups the user belongs to.

Audit trail icon—Link to page that displays the audit trail (previous login times) for that user.

Configuring TACACS+ Servers

This section describes how to add and delete TACACS+ servers. TACACS+ servers provide an effective and secure management framework with built-in failover mechanisms. If you want to make configuration changes, you must be authenticated.

The TACACS+ page shows the IP address, port, retransmit rate, and authentication type (Password Authentication Protocol (PAP)) or Challenge Handshake Authentication Protocol (CHAP) of the TACACS+ server. The TACACS+ servers are tried based on how they were configured.


Note In order to activate TACACS+ servers, you must enable them as described in the "Importing Tasks Into ACS" section on page 15-52.


To configure TACACS+, follow these steps:


Step 1 Choose Administration > AAA.

Step 2 From the left sidebar menu, choose TACACS+. The TACACS+ page appears (see Figure 15-51).

Configuring RADIUS Servers

This section describes how to add and delete RADIUS servers. You must enable RADIUS servers and have a template set up for them in order to make configuration changes.

RADIUS provides authentication of users accessing the network. Authentication requests are sent to a RADIUS server that contains all user authentication and network access information. Passwords are encrypted using RADIUS.

In the event the configured RADIUS server(s) is down, NCS will fall back to local authentication and authorization if the fallback to local option is configured. See the "Configuring AAA Mode" section on page 15-134.


Note In order to activate RADIUS servers, you must enable them as described in the "Importing Tasks Into ACS" section on page 15-52.


To configure a RADIUS server, follow these steps:


Step 1 Choose Administration > AAA.

Step 2 From the left sidebar menu, choose RADIUS. The RADIUS page appears (see Figure 15-52).
