Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide
OL-10101-02
Chapter 1 Overview
Features
Monitoring
Switch LEDs that show port and switch status
Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any port or
VLAN
Note RSPAN is available only in the EI.
SPAN support of Intrusion Detection Systems (IDSs) to monitor, repel, and report network security
violations
Four groups (history, statistics, alarms, and events) of embedded remote monitoring (RMON) agents
for network monitoring and traffic analysis
MAC address notification for tracking the MAC addresses that the switch has learned or removed
Syslog facility for logging system messages about authentication or authorization errors, resource
issues, and time-out events
Layer 2 traceroute to identify the physical path that a packet takes from a source device to a
destination device
Facilities for processing alarms related to temperature, power-supply conditions, and the status of
the Ethernet ports (available only on the Catalyst 2955 switch)
LRE Features (available only on Catalyst 2950 LRE switches)
Data, voice, and video transmission through categorized and noncategorized unshielded twisted-pair
cable (Category 1, 2, and 3 structured and unstructured cable, such as existing telephone lines) in
multi-unit, multidwelling, and multitenant buildings
Up to 15 Mbps of bandwidth to remote Ethernet devices at distances of up to 4921 feet
(1500 meters) on each switch LRE port
Compliance with American National Standards Institute (ANSI) and European Telecommunication
Standards Institute (ETSI) standards for spectral-mode compatibility with asymmetric digital
subscriber line (ADSL), Integrated Services Digital Network (ISDN), and digital telephone
networks
Configuration and monitoring of connections between:
Switch LRE ports and the Ethernet ports on remote LRE customer premises equipment (CPE)
devices, such as the Cisco 575 LRE CPE or the Cisco 585 LRE CPE
CPE Ethernet ports and remote Ethernet devices, such as a PC
Support for connecting to the public switched telephone network (PSTN) through plain old
telephone service (POTS) splitters such as the Cisco LRE 48 POTS Splitter
Support for the rate selection, a utility that allows for automatic selection of transmission rates
through sequences
Support for Reed-Solomon error correction
Support for a protected port on Cisco 585 CPE devices
Support for small form-factor pluggable (SFP) modules instead of Gigabit Interface Converter
(GBIC) modules
