Cisco Network Assistant and Embedded CiscoView
Web-based tools to configure the Catalyst 4500 series switch. Cisco Network Assistant manages
standalone devices, clusters of devices, or federations of devices from anywhere in your intranet. Using
its graphical user interface, you can perform multiple configuration tasks without having to remember
command-line interface commands. Embedded CiscoView is a device management application that can
be embedded on the switch flash and provides dynamic status, monitoring, and configuration
information for your switch.
Visual port status information—The switch LEDs provide visual management of port- and switch-level
status.
For more information on Cisco Network Assistant and Embedded CiscoView, see Chapter 9,
“Configuring Switches with Web-Based Tools.”
Dynamic Host Control Protocol
The Catalyst 4500 series switch uses DHCP in the following ways:
• Dynamic Host Control Protocol server—The Cisco IOS DHCP server feature is a full DHCP server
implementation that assigns and manages IP addresses from specified address pools within the
router to DHCP clients. If the Cisco IOS DHCP server cannot satisfy a DHCP request from its own
database, it can forward the request to one or more secondary DHCP servers defined by the network
administrator.
• Dynamic Host Control Protocol autoconfiguration—With this feature your switch (the DHCP client)
is automatically configured at startup with IP address information and a configuration file.
For more information on configuring the DHCP server, refer to the following URL:

Forced 10/100 Autonegotiation
This feature allows you to configure a port to limit the speed at which it will autonegotiate to a speed
lower than the physically maximum speed. This method of reducing the throughput incurs much less
overhead than using an ACL.
Intelligent Power Management
Working with powered devices (PDs) from Cisco, this feature uses power negotiation to refine the power
consumption of an 802.3af-compliant PD beyond the granularity of power consumption provided by the
802.3af class. Power negotiation also enables the backward compatibility of newer PDs with older
modules that do not support either 802.3af or high-power levels as required by IEEE standard.
