Chapter 1 Overview
Default Settings After Initial Switch Configuration
• Distance Vector Multicast Routing Protocol (DVMRP) tunnelling for interconnecting two
multicast-enabled networks across non-multicast networks
• DHCP relay for forwarding UDP broadcasts, including IP address requests, from DHCP clients
Monitoring Features
• Switch LEDs that provide port- and switch-level status
• 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
• Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any standard
port or VLAN.
Note An ES port cannot be a SPAN source.
• SPAN and RSPAN support of Intrusion Detection Systems (IDS) to monitor, repel, and report
network security violations
• Four groups (history, statistics, alarms, and events) of embedded RMON agents for network
monitoring and traffic analysis
• Syslog facility for logging system messages about authentication or authorization errors, resource
issues, and time-out events
• Layer 2 traceroute to identify the physical path that a packet takes from a source device to a
destination device
Default Settings After Initial Switch Configuration
The switch is designed for plug-and-play operation, requiring only that you assign basic IP information
to the switch and connect it to the other devices in your network. If you have specific network needs,
you can change the interface-specific and system-wide settings.
If you do not configure the switch at all, the switch operates with the default settings listed in Table 1-1.
This table lists the key software features, their defaults, and where to find more information about the
features.
For information about setting up the initial switch configuration (by using Express Setup or the CLI
setup program) and assigning basic IP information to the switch, refer to the hardware installation guide.
