Release Notes for Cisco Subscriber Edge Services Manager 3.3(1)
These release notes are for use with the Cisco Subscriber Edge Services Manager (SESM) 3.3(1). These release notes provide:
New Features and Enhancements
SESM 3.3(1) contains the following new features and enhancements:
•Memory management enhancements to improve performance.
•Captive Portal is now installed when you run a Typical installation (no need for Custom installation).
•Web portal PDA and WAP pages support UTF-8.
•RDP can support non-SSG users.
•You can now change the size of send and receive buffers in RDP and web applications.
•Improved management of backlogs for handling new user requests. You can help to improve performance by configuring the time to wait for a RADIUS ID to become available.
•You can now access session timeout RADIUS attribute information. If the user profile includes the session timeout attribute, you can access it from the SESM session API.
•Support for Red Hat Enterprise Linux AS 3 and Red Hat Enterprise Linux ES 3.
Whitelists Per Location For Non-Proxy Users
The previous release of SESM supported the creation of location-specific whitelists to provide web proxy users with different free access destinations depending on location. This release of SESM extends the support of location-specific whitelists to non-proxy users.
For information about configuring location-specific whitelists, see Cisco Subscriber Edge Services Manager Administration and Configuration Guide.
Location Configuration Using Multiple IP Ranges
You can now use multiple, noncontiguous client IP address ranges to define location awareness using complete ID attributes in the Location MBean.
For information about configuring locations with multiple IP ranges, see Cisco Subscriber Edge Services Manager Administration and Configuration Guide.
File Poller for Dynamic Update of Whitelists and Location Configurations
This release of SESM provides a file poller mechanism that updates location and whitelist URL definitions without requiring you to restart the server. It can also be used to share a configuration file among several applications, so that a configuration that is contained in several applications needs to be maintained only in a single file.
For information about using the file poller, see Cisco Subscriber Edge Services Manager Administration and Configuration Guide.
Support for iPass Users
SESM support for roaming users enables iPass users to connect to the Internet from public hotspots using their iPass accounts. iPass is a software-enabled virtual network operator (VNO) that provides enterprise connectivity services permitting secure access to information and applications on corporate networks.
SESM enables iPass account holders to:
•Connect to the Internet using the iPass Smart Client.
•Connect to the Internet through a browser using the NWSP Login page.
For information about configuring SESM support for iPass users, see Cisco Subscriber Edge Services Manager Administration and Configuration Guide.
Display of RADIUS Reply Messages (Attribute 18 Messages)
NWSP now displays RADIUS attribute 18 messages (also known as RADIUS Reply Message) by default. An attribute 18 message can be returned as a response to an access request. NWSP extracts the attribute 18 messages from the response and displays them to the user in the appropriate pages.
Messages extracted from access-reject responses are displayed in the Login page, while messages extracted from access-accept responses are displayed in the Messages page.
Note In previous releases, SESM extracted attribute 18 messages but did not display them. If you already customized your web portal application to display RADIUS reply messages, you can disable this feature.
For information about configuring RADIUS attribute 18 message display, see Cisco Subscriber Edge Services Manager Web Portals Guide.
Support for Always-on Connectivity (Trusted ID Solution)
The trusted ID solution provides always-on connectivity and removes the need for users to authenticate through SSG more than once from the same device or location. Currently users must authenticate each time they connect. When the always-on connectivity is enabled, after users authenticate for the first time, user information (trusted ID) is saved so that a connection from the same user is recognized and automatically authenticated the next time the user connects. The trusted ID information is the user's MAC address.
The trusted ID solution is implemented using a SESM SPE installation and Cisco Access Registrar (AR) 3.5.4 or later, with SPE light installed.
Note The following known problem with trusted ID exists in AR 3.5.4:
CSCeg88981: Implicit login flag change does not have immediate effect.
Symptoms: User passes an implicit login with Implicit-Auth-Enabled set to FALSE.
Conditions: The Trusted ID flow is in use and the user's Implicit-Auth-Enabled has been changed from TRUE to FALSE. If the user is in the cache from a previous passing explicit login, the first implicit login request following the flag change will pass, but every one after will fail.
Workaround: After changing the flag, manually remove the user from the cache using the release-sessions command in aregcmd.
This problem has been fixed in later releases of AR.
SESM support for the trusted ID solution lets you enable and disable always-on connectivity in user profiles through CDAT, and lets users enable and disable always-on connectivity through the self-care pages in NWSP.
See Cisco Subscriber Edge Services Manager Introduction Guide for information about the trusted ID solution and SESM support for always-on connectivity.
For information about configuring AR for the trusted ID solution, see Cisco CNS Access Registrar User's Guide, 3.5. See Related Documentation for a link to the AR documentation online.

This section provides additional information about using SESM:
SSL Script Generation for Testing
You can generate self-signed SSL certificates for testing environments. The appendix in Cisco Subscriber Edge Services Manager Administration and Configuration Guide provides instructions for this procedure.
This procedure is based on the Sun Java Keytool utility. For more information about Keytool, see the Sun Java website.
Note This procedure is only for development, test, and trial environments. It must not be used in a production environment.
Preventing Memory and Performance Degradation
In session and memory management, the session scavenger daemon, which marks aged sessions for deletion, disrupts or prevents garbage collection from freeing memory. This can result in increased memory consumption, and might lead to performance degradation.
To prevent memory and performance degradation, ensure that:
•The profileCachePeriod attribute is not less than one quarter of the sessionCachePeriod.
•You do not use Agent View for constant monitoring of session status.
JRE and JDK_HOME variable
The startup scripts now inform you when the JRE version used is set from your JDK_HOME variable. If the JRE version used is earlier than JRE 1.4.2, a message informs you to which JRE version it was pointing.
Note You cannot use JRE 1.5.0 with SESM.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
