Chapter 1 Product Overview
Security Features
For information on configuring broadcast suppression, see Chapter 37, “Configuring Unicast Reverse
Path Forwarding.”
Utilities
Supported utilities include the following:
Layer 2 Traceroute
Layer 2 traceroute allows the switch to identify the physical path that a packet takes from a source device
to a destination device. Layer 2 traceroute supports only unicast source and destination MAC addresses.
For information about Layer 2 Traceroute, see Chapter 10, “Checking Port Status and Connectivity.”
Time Domain Reflectometry
Time Domain Reflectometry (TDR) is a technology used for diagnosing the state and reliability of
cables. TDR can detect open, shorted, or terminated cable states. The calculation of the distance to the
failure point is also supported.
For information about TDR, see Chapter 10, “Checking Port Status and Connectivity.”
Debugging Features
The switch has several commands to help you debug your initial setup. These commands are included in
the following command groups:
• platform
• debug platform
For more information, refer to the command reference guide.
Web-based Authentication
The web-based authentication feature, known as Web Authentication Proxy, enables you to authenticate
end users on host systems that do not run the IEEE 802.1X supplicant. When you initiate an HTTP
session, this feature intercepts ingress HTTP packets from the host and sends an HTML login page to
your. You key in the credentials, which the web-based authentication feature sends to the AAA server
for authentication. If authentication succeeds, web-based authentication sends a Login-Successful
HTML page to the host and applies the access policies returned by the AAA server.
For information on configuring web-based authentication, see Chapter 52, “Configuring Web-Based
Authentication.”
