Chapter 1 Overview
Default Settings After Initial Switch Configuration
• 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
• Time Domain Reflector (TDR) to diagnose and resolve cabling problems on 10/100 and
10/100/1000 copper Ethernet ports
• SFP module diagnostic management interface to monitor physical or operational status of an SFP
module
• Digital Optical Monitoring (DOM) of connected SFP modules
• Online diagnostics to test the hardware functionality of the supervisor engine, modules, and switch
while the switch is connected to a live network
• On-board failure logging (OBFL) to collect information about the switch and the power supplies
connected to it
• Enhanced object tracking (EOT) for HSRP to determine the proportion of hosts in a LAN by tracking
the routing table state or to trigger the standby router failover
• IP Service Level Agreements (IP SLAs) support to measure network performance by using active
traffic monitoring
• IP SLAs EOT to use the output from IP SLAs tracking operations triggered by an action such as
latency, jitter, or packet loss for a standby router failover takeover
• EOT and IP SLAs EOT static route support to identify when a preconfigured static route or a DHCP
route goes down
• Flow-based Switch Port Analyzer (FSPAN) to define filters for capturing traffic for analysis
• Embedded event m anager (EEM) for device and system management to monito r key system events
and then act on them though a policy
• Support for EEM 3.2, which introduces event detectors for Neighbor Discovery, Identity, and
MAC-Address-Table
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- and stack-wide settings.
Note For information about assigning an IP address by using the browser-based Express Setup program, see
the getting started guide. For information about assigning an IP address by using the CLI-based setup
program, see the hardware installation guide.
If you do not configure the switch at all, the switch operates with these default settings:
• Default switch IP address, subnet mask, and default gateway is 0.0.0.0. For more information, see
Chapter 3, “Assigning the Switch IP Address and Default Gateway,” and Chapter 24, “Configuring
DHCP Features and IP Source Guard.”
