About This Release

The Ruckus Wireless SmartCell Gateway (SCG) appliance combines a WLAN
access controller with Wi-Fi traffic aggregation, along with a built-in carrier-grade
element management system in a 2U rack-mountable, all-in-one hardware form
factor.
This document provides release information about the SmartCell Gateway features
with notes on known issues, caveats, and workarounds.

What’s New in This Release
This section describes the key features of this SCG release and supplements the
“What’s New” document for release 2.1.

Integration with SmartCell Insight to Provide Network
Statistics
The SCG 2.1.1 is the first SCG release to integrate with SmartCell Insight (SCI) by
providing all raw data for SCI to process and present various network statistics
reports. The SCG implements a JSON over HTTP REST interface for bidirectional
interaction with SCI. Pull and push methods are supported on the SCG to send the
data across.
SCI is a massive scalable application that stores historical raw data from the SCG
for multi-year historical analysis It collects, aggregates, correlates data and provides
the user with the ability to design custom reports with a browser driven, flexible
point-and-click report generation methodology.
SCI is the single point of access into Ruckus Wireless network equipment data and
normalizes the data from multiple SCGs or SCG clusters to simplify the integration
into an existing OSS infrastructure.

About This Release
List of Release Documentation

AAA Enhancement: Accounting On and Off
This feature enhances the handling of Accounting On and Accounting Off requests
at the SCG. In release 2.1.1, customers have the option of having the SCG sending
Accounting On/Off messages to AAA servers. In previous releases, when an
Accounting On or Account Off was received from the AP, the SCG did not take any
action and sent a dummy acknowledgment for the request back to AP. Some
customers use Accounting Off messages to determine the health of the AP and,
upon the receipt of the same, take selective actions. SCG release 2.1.1 is capable
of forwarding these requests to the AAA servers that are configured for the
corresponding WLAN/zone.

Resolved Issues

This section lists the issues in earlier releases that have been resolved in this release.

AAA
• Resolved an issue where accounting statistics are not updated when the SCG
is functioning as a RADIUS accounting proxy for open authenticated clients.
[SCG-16429]
• Resolved a number of issues in the SCG AAA (RADIUS) Accounting Reference
Guide, including some incorrect descriptions. [SCG-14763]
• Resolved an issue where authentication timeout may occur when the number
of subscribers reaches 50,000. [SCG-14686]

AP Zones
• Resolved an issue where a profile that has been created does not appear on the
Profiles page until the user uses the search option. Also resolved an issue where
the AP registration rule does not appear to be applied to an AP that previously
joined the SCG and therefore already has an existing record. Both reported
issues are design intent and the documentation has been updated to explain
these. [SCG-15598]

CLI
• Resolved an issue where the CLI accepts out-of-range values for the GPS
distance setting when creating an AP registration rule. [SCG-15792]
• Resolved an issue where the CLI command
show running-config zone-template
does not list the existing WLAN groups. [SCG-15863]

Hotspot
• Resolved an issue where a Ruckus Wireless AP-initiated accounting stop does
not get proxied to the external AAA for hotspot (WISPr) calls. [SCG-16557]

SmartCell Gateway 200 Release Notes for 2.1.1 Release, 800-70591-001 Rev B

Resolved Issues
Reports

Reports
• Resolved an issue where the timestamp for generated PM reports is 30 minutes
earlier than the actual report generation time.
• Resolved an issue where email notification may not work for any of the reports.
• Resolved an issue where the timestamp for the Client vs Airtime report may be
incorrect. For example, if the report was generated manually at 15:50, the
timestamp may show 13:30. [SCG-15347]

Scaling and Performance
• Resolved an issue where the QinQ to GTPV1+V2:SM process stops responding
during a heavy load. [SCG-16270]
• Resolved an issue where an administrator may be unable to log to the SCG web
interface during a heavy load in a two-node TTG cluster. [SCG-14895]

Upgrading
• Resolved an issue where upgrading from 2.1.1.0.79 to 2.1.1.0.94 may fail in a
two-node cluster. One node may keep the 2.1.1.0.79 image while the other node
may be upgraded successfully to 2.1.1.0.94. [SCG-16460]

Web Interface
• Resolved an issue wherein when deleting a 32 L2oGRE /L3oGRE WLAN zone,
the corresponding service profile for L2oGRE /L3oGRE cannot be removed.
[SCG-16311]
• Resolved an issue where the Monitor > Clients > Associated Clients page
may show only 10,000 associated clients, even when the actual number of
associated clients is more than 10,000. [SCG-14766]

Caveats, Limitations, and Known
Issues

This section lists the caveats, limitations, and known issues in this SCG release.
• The SCG web interface becomes unreachable after the SCG is upgraded to
release 2.1.1.0.126. The workaround to this issue consists of adding a static
route to the management interface – using either the web interface (before the
upgrade) or the CLI (after the upgrade).
Workaround 1: Before the upgrade, add the static route using the web interface.
Before you perform the upgrade, follow these steps to add the static route to
the management interface from the web interface.
CAUTION! You must perform this procedure BEFORE you perform the upgrade.
a Log on to the web interface.
b Go to Configuration > SCG System > Cluster Planes > Static Route.
c Click Create New, and then configure the following static route settings:
-

Network Address: Enter the destination IP address of this route. In the
screen shot below, 172.19.0.0 is an external subnet where the SCG
web interface can be accessed.

Subnet Mask: Enter a subnet mask for the IP address above.

Gateway: Enter the IP address of the gateway router. In the screen shot
below, 157.157.157.33 is the gateway router for the management
interface.

Interface: Select Management Interface.

Metric: This represents the number of routers between the network and
the destination.

d Click Apply to save the static route.
e Perform the upgrade to release 2.1.1.0.126.
f

After the upgrade, access the web interface.

• On a standalone SCG, the data blade kernel stops responding during a heavy
load in TTG mode. [SCG-15163]
• When the SCG is configured to generate a report on a daily basis, the generated
report displays the time element (for example, 08:00), which may confuse some
users. [SCG-15923]
• In a two-node cluster, not all existing guest access sessions that are using the
same user name are deleted when Disconnect Messages (DMs) are sent from
the AAA server (with RADIUS Accounting proxy enabled) for that user name.
[SCG-14150]
• Hotspot (WISPr) logoff does not work when a UE roams to different AP and
different control blade. [SCG-14011]
• The critical alarm “Data blade disconnected from the network” appears on the
Monitor page of the SCG web interface, even when the data blade is online and
operating normally. [SCG-14232]
• The web interface is inaccessible from Internet Explorer 9 and 10 when compatibility mode is enabled. [SCG-16046]
• Historical client statistics do not list all of the UEs that belong to third party AP
zones. [SCG-16337]
• When a Ruckus Wireless AP is rebooted, Accounting On request is not sent for
all scenarios. [SCG-15466]
• Manual reboot of the SCG is required for the following scenarios:
• Changing the Cluster IP/Gateway
• Changing the Control IP/Gateway [SCG-16877]
• After the SCG is reset to factory default settings, the SCG allows the data blade
interface IP address and gateway address to be on different subnets. [SCG16491]
• Handover between mesh APs generates multiple accounting sessions. [SCG14826]

SmartCell Gateway 200 Release Notes for 2.1.1 Release, 800-70591-001 Rev B

Caveats, Limitations, and Known Issues

• Various issues related to guest pass profile creation and retrieval exist on the
SCG web interface and in the SmartCell Gateway 200 Administrator Guide.
[SCG-15596]
• Unzipping the SCG-AP statistics files generates errors. [SCG-15074]
• The SCG only exports up to 45,000 events to the CSV file, even when more than
45,000 events have been generated. [SCG-8445]
• The framed IP address attribute for Accounting is unsupported for IPv6 clients.
[SCG-15660]
• The datablade sends traffic even after GGSN path failure is detected. [SCG15412]
• An invalid RADIUS authenticator is sent towards the AP when RADIUS reject is
initiated by the SCG due to the absence of CUI for a TTG call. [SCG-16864]
• Walled garden services do not provide access to HTTPS web pages. [SCG13650]
• The SCG allows the same IP address to be assigned to the control blade, data
blade, and cluster blade interfaces. [SCG-13702]
• After a node is removed from a cluster, the logon page keeps reloading when
an administrator attempts to log on and a high number of APs become
disconnected from the SCG. [SCG-15351]
• The SCG fails over to the secondary AAA server even when the primary AAA
server responds within the configured response window. [SCG-14528]
• If the response window (in AAA Health Check Policy) is set to a value higher than
30 seconds, it automatically reverts to the default setting (30 seconds).
[SCG-14527]
Workaround
Make sure that the response window is set to a value that is equal or lower than
30 seconds.
• The RADIUS failover mechanism does not function correctly when the NAS
failover and health check policy settings are configured incorrectly.
Workaround
To ensure that the RADIUS failover mechanism functions correctly, either accept
the default values for Response Window, Zombie Period, and Revive Interval, or
make sure that the value for Response Window is always higher than the value
for RADIUS NAS request timeout multiplied by the value for RADIUS NAS max
number of retries. [SCG-16092]

SmartCell Gateway 200 Release Notes for 2.1.1 Release, 800-70591-001 Rev B

Caveats, Limitations, and Known Issues

• The SCG may display the timestamp of some events and alarms as “2014”
(instead of the complete date and time). This issue occurs when an AP is unable
to join the SCG and, consequently, unable to synchronize its system time with
the NTP server configured on the SCG. Table 2 lists the alarms and events that
are affected by this known issue. [SCG-14271]

SmartCell Gateway 200 Release Notes for 2.1.1 Release, 800-70591-001 Rev B

Interoperability Information

Note that a supported ZoneFlex AP configured to currently operate with ZoneDirector will require an upgrade to an SCG-200 approved software release prior to
inter operating with a SmartCell Gateway controller. Once an AP switches over to
SmartCell Gateway 200, it will no longer be able to communicate with its old
ZoneDirector controller.
