Cisco Prime Network Infrastructure 1.4
Cisco Prime Infrastructure is a network management platform that supports lifecycle management of your entire network infrastructure from one GUI (Figure 1). Prime Infrastructure provides network administrators with a "single pane of glass" solution for provisioning, monitoring, optimizing, and troubleshooting both wired and wireless devices. Robust GUIs make device deployments and operations simple and cost-effective.
Figure 1. Cisco Prime Infrastructure 1.4
Cisco Prime Infrastructure 1.4 with Cisco Wireless Release 7.5 adds support for new features, as described in Table 4.
Table 4. New Cisco Prime Infrastructure 1.4 Features That Support Cisco Wireless Release 7.5
Management support for Release 7.5 and associated features
Support for new access point platforms (Aironet 3600p, 802.11ac module, etc.) and other features. 802.11.w. Proactive capacity alarm or notification for RFID, clients. Web authorization and Dot1x support. Return additional 6 parameters for Dynamic Host Configuration Protocol (DHCP) option 82 configuration.
Centralized configuration, monitoring, and troubleshooting for the new access point and controller features.
Management support (configuration and monitoring) for Policy Classification Engine on wireless controller (Release 7.5 and later)
Policy classification enables customers to perform client (network endpoint) profiling at the controller and then configure and enforce policies on a per-device or per-user basis.
Policy Classification Engine on wireless controller enables this capability without the Cisco Identity Services Engine (ISE). Note that the ISE offers a much richer set of features, such as device profiling, onboarding, posture, and extensive policy management. The client device identification is based on protocols such as HTTP, DHCP, and MAC. The profiling can then be done based on factors including device type, user role/ID/password, location, time of day, EAP type, etc. Customers can configure and enforce policies on a per-device or per-user basis. Cisco Prime Infrastructure provides a scalable and easy mechanism to configure and monitor this capability on one or more wireless controllers using templates.
Configuration of sleeping client enhancement feature
Caches client credentials for a configurable period of up to 30 days (720 hours).
Previously (until Release 7.4), web authentication-enabled client devices connected to a WLAN via a wireless controller had to reauthenticate with login credentials (ID/password) when waking up from sleep. Release 7.5 added the ability to cache client credentials for a configurable period of up to 30 days (720 hours) and allows clients to reconnect to the network without having to reauthenticate on wakeup after sleep. Cisco Prime Infrastructure provides the necessary templates to configure the parameters on a per-WLAN basis and the ability to apply them to one or more wireless controllers.
Management support (configuration and monitoring) for a FlexConnect enhancement feature that allows customers to do WLAN-to-VLAN mapping at the FlexConnect group level
Allows customers to do WLAN-to-VLAN mapping at the FlexConnect group level.
Before Release 7.5, WLAN-to-VLAN mapping was configured on a per-access point basis, making this mapping difficult in deployments that had large numbers of access points in a FlexConnect group. This feature allows customers to do WLAN-to-VLAN mapping at the FlexConnect group level, making it scalable. Cisco Prime Infrastructure provides the necessary templates to configure the parameters and apply them to one or more wireless controllers.
Management support for new access point hardware: 802.11ac module: A field-upgradable add-on module to the Aironet 3600 Series
Simple Network Management Protocol (SNMP) MIB enhancements to the 802.11ac module for the Aironet 3600e or 3600 access points. Same form factor as the Cisco Aironet Access Point Module for Wireless Security and Spectrum Intelligence. Aironet 3600 Series maintains dual-band support for 2.4 and 5 GHz, supporting 802.11b/g/n on 2.4 GHz and 802.11a/ac/n on 5 GHz.
802.11ac module for the Aironet 3600e or 3600 access point allows customers to deploy 802.11ac in an enterprise using their existing Aironet 3600. The Aironet 3600 maintains dual-band support for 2.4 and 5 GHz, supporting 802.11b/g/n on 2.4 GHz and 802.11a/ac/n on 5 GHz. Cisco Prime Infrastructure (starting with Release 1.4) will provide support for configuring and monitoring the main radio and the module radio (with support for additional configuration such as channel width, dynamic channel assignment [DCA], Modulation and Coding Scheme [MCS], etc.)
Management support (configuration, templates) for a feature that enables customers to manage LED settings on the access point
Enables customers to manage LED settings (on/off duration and schedule) on the access point.
Beginning with Release 7.5, customers can configure access point LED capabilities from the wireless controller and Prime Infrastructure. Using a lightweight access point configuration template, customers can now configure the duration and schedule for access point LEDs. This feature is critical to customers in specific sectors (such as healthcare).
Management support for FlexConnect local authentication enhancement, adding EAP-TLS and PEAP
EAP-TLS and PEAP options for FlexConnect local authentication.
Release 7.5 has enhanced FlexConnect local authentication by adding EAP-TLS and PEAP. Previously we supported only Lightweight EAP (LEAP) and EAP-Fast. Cisco Prime Infrastructure (starting with Release 1.4) will provide support for configuration of these two additional authentication methods.
Reporting enhancement: Inventory report will show dead radios (in both Lightweight Access Point Protocol [LWAPP] and autonomous access points)
Inventory report to show dead radios (in both LWAPP and autonomous access points).
Release 7.5 has enhanced reporting functionality to show dead radios for both LWAPP and autonomous access points.
Management support for new functionality on MSE: Billboard and proxy services
Billboard and proxy services.
Release 7.5 has added the ability to launch billboard services. This allows customers to enhance in-venue engagement with venue visitors and customers carrying Wi-Fi-enabled mobile devices. Cisco Prime Infrastructure provides the configuration and templates necessary to configure billboard and proxy services parameters on the MSE.
Management support for client SSO on Cisco WLAN
Client SSO in Cisco WLAN.
Release 7.5 has introduced stateful switchover of the wireless clients that have successfully connected and are transferring data. This feature can be enabled in deployments where an access point serving the client is connected to a wireless controller in a 1:1 HA configuration. The key benefit of this feature is that when the primary wireless controller in this configuration goes down, access points and associated clients transition to the secondary controller without affecting the service. Cisco Prime Infrastructure 1.4 provides the configuration and templates necessary to configure this feature on wireless controllers running Release 7.5.
Management support for cable modem monitoring
Enables customers to monitor the health of the cable modem in the Aironet 1552C Outdoor Mesh Access Point.
Allows service provider customers to monitor the health of cable modems with Cisco Prime Infrastructure. Currently customers have to log in to their Cable Modem Termination System (CMTS) to monitor the cable modem module in the Aironet 1552C. With this feature, we link access points, wireless controllers, and cable modems and their associated CMTS, enabling customers to monitor the cable modem and access point from one tool.
Management support for Proxy Mobile IP (PMIP) v6 Mobile Access Gateway (MAG) implementation and enhancements
Support for PMIPv6 MAG implementation and enhancements.
Release 7.5 enhances support for PMIPv6 by adding the following two capabilities to the wireless controller: (a) support for centralized web authentication scenarios; (b) support for dynamic attributes - MAG support for obtaining PMIPv6 attributes (such as local mobility anchor [LMA] address, service selection type, etc.) dynamically from an AAA server. Customers can now use Cisco Prime Infrastructure to configure and monitor these features.
