Features
Certain Cisco Long-Reach Ethernet (LRE) customer premises equipment (CPE) devices are not
supported by certain Catalyst 2950 LRE switches. In Table 1-2, Yes means that the CPE is supported by
the switch; No means that the CPE is not supported by the switch.
This section describes the features supported in this release:
Note Some features require that you have the EI installed on your switch. For a list of the switches that support
the EI, see Table 1-1, or refer to the release notes for this release.
Ease of Use and Ease of Deployment
• Express Setup for quickly configuring a switch for the first time with basic IP information, contact
information, switch and Telnet passwords, and Simple Network Management Protocol (SNMP)
information through a browser-based program
• User-defined Smartports macros for creating custom switch configurations for simplified
deployment across the network
• Cluster Management Suite (CMS) software for simplifying switch and switch cluster management
through a web browser, such as Netscape Communicator or Microsoft Internet Explorer, from
anywhere in your intranet
• Switch clustering technology used with CMS for
– Unified configuration, monitoring, authentication, and software upgrade of multiple switches
(refer to the release notes for a list of eligible cluster members).
– Automatic discovery of candidate switches and creation of clusters of up to 16 switches that can
be managed through a single IP address.
– Extended discovery of cluster candidates that are not directly connected to the command switch.
