Catalyst 3750-X and 3560-X Switch Software Configuration Guide
OL-25303-03
Chapter 1 Overview
Software Features
•
StackPower technology on Catalyst 3750-X switches running the IP Base or IP Services feature set.
When power-stack cables connect up to four switches, you can manage the individual switch power
supplies as a single power supply for power sharing or redundancy for switches and connected
devices.
• Switch clustering technology for
–
Unified configuration, monitoring, authentication, and software upgrade of multiple,
cluster-capable switches, regardless of their geographic proximity and interconnection media,
including Ethernet, Fast Ethernet, Fast EtherChannel, small form-factor pluggable (SFP)
modules, Gigabit Ethernet, Gigabit EtherChannel, 10-Gigabit Ethernet, and 10-Gigabit
EtherChannel connections. For a list of cluster-capable switches, see the release notes.
– Automatic discovery of candidate switches and creation of clusters of up to 16 switches that can
be managed through a single IP address.
–
Extended discovery of cluster candidates that are not directly connected to the command switch.
• Smart Install to allow a single point of management (director) in a network. You can use Smart
Install to provide zero touch image and configuration upgrade of newly deployed switches and
image and configuration downloads for any client switches. For more information, see the
Cisco
Smart Install Configuration Guide on Cisco.com.
•
Smart Install enhancements in Cisco IOS Release 12.2(55)SE supporting client backup files,
zero-touch replacement for clients with the same product-ID, automatic generation of the imagelist
file, configurable file repository, hostname changes, transparent connection of the director to client,
and USB storage for image and seed configuration.
• Smart Install enhancements in Cisco IOS Release 12.2(58)SE including the ability to manually
change a client switch health state from denied to allowed or hold for on-demand upgrades, to
remove selected clients from the director database, to allow simultaneous on-demand upgrade of
multiple clients, and to provide more information about client devices, including device status,
health status, and upgrade status.
•
Call Home to provide e-mail-based and web-based notification of critical system events. Users with
a service contract directly with Cisco Systems can register Call Home devices for the Cisco Smart
Call Home service that generates automatic service requests with the Cisco TAC.
Performance Features
• Cisco EnergyWise manages the energy usage of endpoints connected to domain members.
For more information, see the Cisco EnergyWise documentation on Cisco.com.
• Cisco EnergyWise Phase 2.5 enhancements that add support for a query to analyze and display
domain information and for Wake on LAN (WoL) to remotely power on a WoL-capable PC.
•
Autosensing of port speed and autonegotiation of duplex mode on all switch ports for optimizing
bandwidth.
• Automatic-medium-dependent interface crossover (auto-MDIX) capability on 10/100- and
10/100/1000-Mb/s interfaces and on 10/100/1000 BASE-TX SFP module interfaces that enables the
interface to automatically detect the required cable connection type (straight-through or crossover)
and to configure the connection appropriately.
•
Support for the maximum packet size or maximum transmission unit (MTU) size for these types of
frames:
– Up to 9216 bytes for routed frames.
