Troubleshooting Maintenance Release Installs in High Availability Implementations

If you are unable to apply this maintenance release in a High Availability (HA) implementation, check whether your network bandwidth, throughput and latency meets the network requirements recommended in Network Throughput Restrictions on HA section in the Cisco Prime Infrastructure 3.9 Administrator Guide. In a few cases, continued or intermittent throughput problems can cause a complete failure. If you believe this has occurred, contact Cisco TAC for support.

If you are unable to verify that this maintenance release has been successfully installed on a Prime Infrastructure server, or one or both of the servers fails to restart properly after installing the maintenance release, you may need to re-image the server as explained in Before You Begin Installing the Maintenance Release before continuing.

In all cases, you can use the backup-logs command on one or both servers to get information on the source of the failure. For more information, see the backup-logs section in the Cisco Prime Infrastructure 3.9 Command Reference Guide .

Prime Data Migration Tool

Prime Data Migration Tool is now available in 3.9.1. This tool helps you to migrate your Cisco Prime Infrastructure 3.9.1 data to Cisco DNA Center.

You can launch the Prime Data Migration Tool from the Prime Infrastructure 3.9.1 home page from:

Mega Menu > Cisco DNA Center coexistence - You can now directly open Cisco DNA Center coexistence from the Mega Menu page.

Settings > Getting Started > Cisco DNA Center coexistence - Launch Cisco DNA Center from the Getting Started page.

For more information on using Prime Data Migration Tool in 3.9.1, see the Cisco Prime Infrastructure to Cisco Digital Network Architecture Center Co-existence Guide.

Client SNR Summary

This is a new report type that provides a summary of the client SNR for good, average and low SNR category. You can configure the SNR category range from the Client settings page (Administration > System Settings > Client and User > Client).

Port Reclaim Report

This report displays the unused ports based on the last usage time. It displays port information like device name, port description, MAC address, last usage time, and the admin and operational status.

From 3.9.1, this report takes the data directly from the device and displays the actual usage time. In earlier releases, the initial time of the device was taken as the time the device was added to Prime Infrastructure.

Daily Unique Client Count

This report was added in 3.9 to display the daily unique clients and their details. In 3.9.1, this report shows only the daily unique client count. A unique client is determined by the MAC address of the client that connects at least once daily.

Client Count

This report displays the total number of active clients on your wireless network. The Client Count report displays data on the numbers of clients that connected to the network through a specific device, in a specific geographical area, or through a specific or multiple SSIDs.

In 3.9.1, this report includes roaming clients. By default, roaming client count is disabled. To enable the roaming client count, choose Administration > System Settings > Client and User > Client and check the Roaming Client Count check box.

Inventory

This report displays the inventory data for the devices in your network. In 3.9.1, for disassociated access points, a new Disassociated Date column is available.

AP Radio Downtime Summary

This report shows the time the radio was down for AAPs and Unified APs that are managed by Prime Infrastructure.

In 3.9.1, % of excluded Down time and Excluded Down time for columns and a new filter condition Radio Admin Status Consideration are available.

Cisco IOS/IOS XE Release 17.5

Prime Infrastructure 3.9.1 supports Cisco IOS/IOS XE Release 17.5.

Supported Access Points

Prime Infrastructure 3.9.1 supports the following lightweight APs:

• Cisco Catalyst 9124AXI Series Unified Access Points

• Cisco Catalyst 9124AXD Unified Access Points

Both these access points have Neighbor Discovery Protocol (NDP) capability (On-Channel and Off-Channel).

Neighbor Discovery Protocol (NDP)

Prerequisites for NDP

Access Points must be associated with an eWLC controller running Cisco IOS/IOS XE Release 17.5.

Information about NDP

NDP is a critical component of Cisco’s auto RF feature, Radio Resource Management (RRM). NDP provides over-the-air (OTA) messages between access points. It monitors and manages what each AP sees in the radio frequency (RF). It is how every AP sees other APs in an RF group or neighborhood. NDP forms the basis of many algorithms within Cisco RRM. By default, NDP packets are transmitted off channel on the RHL radio.

You can configure the NDP mode from the controller as:

• Auto /On-Channel (Serving channel)

• Off-Channel (RHL radio)

NDP capability of the AP can be:

• On-Channel (Serving channel)

• Off-Channel (RHL radio)

• Both

Configuring NDP in Prime Infrastructure

1. To configure the NDP mode from the controller in Prime Infrastructure:

   Choose Configuration > Network > Network Devices > Device Groups > All Devices > xxx_ eWLC controller > 802.11a parameters or 802.11b parameters > .

   Choose the RRM Neighbor Discover Mode from the drop-down list.

2. To create an RF profile and provision it on to multiple controllers using the template:

   Choose Configuration >Wireless technologies > Cisco Catalyst 9800 Configuration > .

   In the RF Profile Detail window, choose NDP and the Channel Width from the drop-down lists.

3. To configure the RRM Neighbor Discover Mode in a configuration template and provision it onto multiple controllers:

   Choose Configuration > Templates > Features & Technologies > Controller > 802.11a/n/ac/ax or 802.11b/g/n/ax > Parameters > .

   Choose the RRM Neighbor Discover Mode from the drop-down list.

4. To view or verify the configured NDP capability and NDP mode of an AP:

   Choose Configuration > Network > Network Devices > Device Groups > Device Type > Unified AP > xxx_9105AXW > 802.11a/n/ac/ax > .
