Chapter 1 Overview
Default Settings After Initial Switch Configuration
Power over Ethernet Features
These are the Power over Ethernet (PoE) features:
•
Ability to provide power to connected Cisco pre-standard and IEEE 802.3af-compliant powered
devices from Power over Ethernet (PoE)-capable ports if the switch detects that there is no power
on the circuit.
• Support for CDP with power consumption. The powered device notifies the switch of the amount of
power it is consuming.
•
Support for Cisco intelligent power management. The powered device and the switch negotiate
through power-negotiation CDP messages for an agreed power-consumption level. The negotiation
allows a high-power Cisco powered device to operate at its highest power mode.
• Automatic detection and power budgeting; the switch maintains a power budget, monitors and tracks
requests for power, and grants power only when it is available.
Monitoring Features
These are the monitoring features:
• 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.
• Enhanced object tracking for HSRP.
Default Settings After Initial Switch Configuration
The switch is designed for plug-and-play operation, requiring only that you assign basic IP information
to the switch and connect it to the other devices in your network. If you have specific network needs,
you can change the interface-specific and system- and stack-wide settings.
