Catalyst 3750-X and 3560-X Switch Software Configuration Guide
OL-21521-01
Chapter 1 Overview
Features
•
IPv6 default router preference (DRP) for improving the ability of a host to select an appropriate
router
router
•
Support for EIGRP IPv6, which utilizes IPv6 transport, communicates with IPv6 peers, and
advertises IPv6 routes
advertises IPv6 routes
•
IP unicast reverse path forwarding (unicast RPF) for confirming source packet IP addresses.
•
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 feature set)

•
NSF-capable routing for OSPF and EIGRP that allows the switch to rebuild routing tables based on
information from NSF-aware and NSF-capable neighbors (only Catalyst 3750-E Catalyst 3750-X
switches)
information from NSF-aware and NSF-capable neighbors (only Catalyst 3750-E Catalyst 3750-X
switches)
•
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 IEEE 802.3at (PoE+), that increases the available power for powered devices from
15.4 W to 30 W per port.
15.4 W to 30 W per port.
•
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.

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.
requests for power, and grants power only when it is available.
•
Ability to monitor the real-time power consumption. On a per-PoE port basis, the switch senses the
total power consumption, polices the power usage, and reports the power usage.
total power consumption, polices the power usage, and reports the power usage.
•
StackPower technology on Catalyst 3750-X switches running the IP base or IP services feature set.
Monitoring Features
•
Switch LEDs that provide port- and switch-level status on Catalyst 3560-X switches
•
Switch LEDs that provide port-, switch-, and stack-level status on Catalyst 3750-X switches
•
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
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
