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.

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.
