Chapter 1 Overview
Features
• Support for EEM 3.2, which introduces event detectors for Neighbor Discovery, Identity, and
MAC-Address-Table.
• Switch LEDs that provide port-, switch-, and stack-level status
• MAC address notification traps and RADIUS accounting for tracking users on a network by storing
the MAC addresses that the switch has learned or removed
• Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any port or
VLAN
• SPAN and RSPAN support of Intrusion Detection Systems (IDS) to monitor, repel, and report
network security violations
• Four groups (history, statistics, alarms, and events) of embedded RMON agents for network
monitoring and traffic analysis
• 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
• Time Domain Reflector (TDR) to diagnose and resolve cabling problems on 10/100/1000 copper
Ethernet ports
• SFP module diagnostic management interface to monitor physical or operational status of an SFP
module
• Generic online diagnostics to test hardware functionality of the supervisor engine, modules, and
switch while the switch is connected to a live network.
• On-board failure logging (OBFL) to collect information about the switch and the power supplies
connected to it (Catalyst 2960-S only)
• Enhanced object tracking for HSRP.
• Digital optical monitoring (DOM) to check status of X2 small form-factor pluggable (SFP) modules
