Catalyst 3560 Switch Software Configuration Guide
OL-8553-06
Chapter 1 Overview
Features
•
Nonstop forwarding (NSF) awareness to enable the Layer 3 switch to continue forwarding packets
from an NSF-capable neighboring router when the primary route processor (RP) is failing and the
backup RP is taking over, or when the primary RP is manually reloaded for a nondisruptive software
upgrade (requires the IP services image)

•
The ability to exclude a port in a VLAN from the SVI line-state up or down calculation
•
Intermediate System-to-Intermediate System (IS-IS) routing supports dynamic routing protocols for
Connectionless Network Service (CLNS) networks.\
Connectionless Network Service (CLNS) networks.\
Power over Ethernet 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.
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.
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.

Support for HSRP Version 2 (HSRPv2)
Monitoring Features
•
EOT and IP SLAs EOT static route support identify when a preconfigured static route or a DHCP
route goes down

•
Embedded event manager (EEM) for device and system management to monitor key system events
and then act on them though a policy (requires the IP services image)

•
Switch LEDs that provide port- and switch-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
