Introduction
Cisco IOS Release 11.2(8)SA6 supports the Catalyst 2900 series XL and the Catalyst 3500 series XL switches. These workgroup Ethernet switches can connect to 10/100 Ethernet, Gigabit Ethernet, and Asynchronous Transfer Mode (ATM) devices as backbone switches, or they can be used in mixed configurations that connect hubs, servers, and desktops.
Switches with this IOS release are available in a standard edition or with Enterprise Edition Software. This guide describes the features that are common to both versions. The IOS Desktop Switching Enterprise Edition Software Configuration Guide describes those features that are only in the Enterprise Edition Software.
You can upgrade your switch to Enterprise Edition Software by downloading a new image from Cisco Connection Online. lists the switches that support IOS
Release 11.2(8)SA6.Summary of Key Features
This section describes the key features of IOS Release 11.2(8)SA6. in "," lists each of these features with its default setting and a cross-reference to the section describing it. The following are the key features of this IOS release:
•
Automatic discovery and creation of clusters of up to 16 switches that can be managed through a single IP address. Cluster support includes:
•
•
•
•
•
•
•
•
•
The following Enterprise Edition Software features are documented in the Cisco IOS Desktop Switching Enterprise Edition Software Configuration Guide:
•
•
•
•
Supported Hardware
When switches are grouped into clusters, one switch is the command switch, and the other switches are member switches. The IP address for the entire cluster is assigned to the command switch, and it distributes configuration information to the other switches. and describes each switch supported by this release and shows those switches that can act as command switches.

Management Options
IOS Release 11.2(8)SA6 supports these management interfaces:
•
•
•
HTML Interfaces
Embedded HTML-based management tools display live images of switches and graphical user interfaces.
Depending on your task, you can monitor and configure the supported switches by using the following HTML interfaces:
•
•
•
IOS Command-Line Interface
You can access the IOS CLI by connecting a PC or terminal to the console port on the switch rear panel or by using Telnet. "," describes how to use IOS, and "," and "," describe the commands to use for specific configuration tasks.
SNMP Network Management Platforms
You can manage switches by using an SNMP-compatible management station running such platforms as HP OpenView or SunNet Manager. In a cluster configuration, the command switch manages communication between the SNMP management station and all switches in the cluster. The switch supports a comprehensive set of MIB extensions and MIB II, the IEEE 802.1D bridge MIB, and four Remote Monitoring (RMON) groups.
Deployment Examples
This section describes how you can use IOS Release 11.2(8)SA6 with the Catalyst 3500 series XL and Catalyst 2900 series XL series switches.
Wiring Closet Aggregation
The cluster-management capabilities of IOS Release 11.2(8)SA6 and the Gigabit Ethernet capabilities of the Catalyst 3500 XL switches can aggregate traffic for Cisco routers or Layer 3 switches. The 10/100 capabilities of the Catalyst 2900 series XL deliver high-speed connections to desktops and servers. shows such a configuration.
