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
