Cisco Prime Infrastructure 3.1.1 Release Notes

Before You Begin Installing the Maintenance Release

Caution Once you install this maintenance release, you cannot un-install or remove it.

---

Since the maintenance release is not removable, it is important to have a way to revert your system to the original version in case hardware or software problems cause the maintenance release installation to fail.

To ensure you can do this, take a backup of your system before downloading and installing this UBF maintenance release.

To restore the backup of the Prime Infrastructure 3.1 installation, follow these steps:

1. Reinstall Prime Infrastructure 3.1 from an OVA or ISO distribution.

2. Restore the data from the backup that you made before applying the maintenance release 3.1.1

Similarly, if you are running Prime Infrastructure 3.1 in a Virtual Machine (VM) and your organization permits taking VM snapshots, stop Prime Infrastructure and use the VMware client to take a VM snapshot before applying this maintenance release. Store the snapshot in an external storage repository, and restore from the snapshot if the maintenance release installation is unsuccessful.

If you are installing this maintenance release as part of a High Availability (HA) implementation, see Before You Begin Setting Up High Availability in the Cisco Prime Infrastructure 3.1 Administration Guide.

• Make sure that you have completed the recommended preparation steps given in Before You Begin Installing the Maintenance Release.

Note Prime Infrastructure 3.1.1 can be applied only in primary and secondary standalone servers. The server will restart automatically once the installation is complete. The restart typically takes 25 to 35 minutes. You cannot apply Prime Infrastructure 3.1.1 when HA is enabled.

• If you are installing Cisco Prime Infrastructure Maintenance Release 3.1.1 on High Availability (HA) paired servers, you will get the following error message:

For more details, see Removing HA Via the GUI in the Cisco Prime Infrastructure3.1 Administrator Guide.

• Continue the patching once HA removed completely. For more details, see the Patching New High Availability Servers section in the Cisco Prime Infrastructure 3.1 Administration Guide.
• 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 3.1 Administration 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 Command Reference Guide for Cisco Prime Infrastructure 3.1.

Enabling Data Deduplication

Data deduplication allows you to identify authoritative data sources for the corresponding location groups.

Prime infrastructure stores all the data it receives about network usages from all the sources (including any duplicate data that it may receive from multiple sources). When you specify authoritative data sources, only the data from the specified source is displayed when you view a particular site.

The data deduplication page allows you to specify a data source per a specific site. For example, if you have a Network analysis module (NAM) at a branch office as well as Netflow data that is sent from the same branch, you can choose to see the site information as it is reported by the NAM or netflow data with authoritative data source.

The two authoritative data sources are

• System detected – It is based on the managed device product families. You can change the device family selection precedence. To change the precedence, click the settings icon and drag and drop the device families. The authoritative datasources are selected according to this precedence.
• Customized – You can pick and choose from the managed data source.

Step 1 Choose Services > Application Visibility & Control > Data Deduplication. The Data Deduplication page appears.

Step 2 Click System Detected to identify the data sources in the location group or select the customized to select the data sources.

Step 3 Click Save.

Step 4 Click Apply.

Prime Infrastructure Report Data Retention Periods

The report shows hourly, daily or weekly data depending on the data retention period configured by choosing Administration > Settings > System Settings > General > Data Retention. The data is retrieved from the database based on the following conditions.

If the period is:

1. Up to last 1 day, the data is fetched from raw table.

2. From last 2 days to 4 weeks, the data is fetched from a hourly aggregated table.

3. From previous month calendar to last 12 week, the data is fetched from daily aggregated table.

4. From last 6 months to last 1 year, the data is fetched from a weekly aggregated table.

The valid range for performance data retention period is:

1. Short term Data Retain Period:1 to 31 days.

2. Long term Data Retain Period: 2 to 756 days.

3. Medium term Data Retain Period: 7 to365 days.

4. Hourly Data Retain Period: Valid Range: is 1 to 31 hours.

Cisco Aironet 2800 Series and 3800 Series APs

Cisco 2800 AP and Cisco 3800 AP are highly versatile and deliver most of the functionalities of any access points available in the industry.

The following enhancements have been made to Cisco Prime Infrastructure to support Cisco 2800 AP and Cisco 3800 AP in this release:

• Supports XOR radio slot where the Wi-Fi radio can be switched between 2.4 GHz and 5 GHz and vice versa in slot 0.
• Supports channel width of 160 MHz. Dynamic bandwidth selections allow the APs to dynamically switch between 20 MHz, 40 MHz, 80 MHz, and 160 MHz channels depending on the RF channel conditions.
• Cisco CleanAir technology is enhanced to support 160 MHz channel width. This provides proactive and high-speed spectrum intelligence across 20 MHz, 40 MHz, 80 MHz, and 160 MHz channels.
• Multi-Gigabit interface support on the access point.
• A new antenna, AIR-ANT2544V4M-R8 has been introduced.

The following enhancements have been made to Sitemaps:

• Site Maps view—Displays the number of 802.11a/n/ac, 802.11 b/g/n radios available on the campus, building, floor, and the outdoor area. When the XOR radios on a floor or outdoor area change their modes to either serving or monitor and the band changes to 802.11a or 802.b, then the corresponding counts in the Site Map page changes
• Building view—Displays the number of 802.11a and 802.11b radios in each floor along with the clients attached to each band (802.11a and 802.11b). When the XOR radios in these floors change their band, then the corresponding client count changes.
• Position AP screen—You can choose either internal or external antenna for 802.11 a/b/g/n radio slots.
• Floor view—The following features have been updated:

– Icon View

– AP/Radio Filter

– Heatmap Filter
