Chapter1 Overview
Default Settings After Initial Switch Configuration
•Egress queues and scheduling
–
Four egress queues per port
–
WTD as the congestion-avoidance mechanism for managing the queue lengths and providing
drop precedences for different traffic classifications
–
SRR as the scheduling service for specifying the rate at which packets are dequeued to the
egress interface (shaping or sharing is supported on egress queues). Shaped egress queues are
guaranteed but limited to using a share of port bandwidth. Shared egress queues are also
guaranteed a configured share of bandwidth, but can use more than the guarantee if other queues
become empty and do not use their share of the b andwidth.

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 port or
VLAN
•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 n etwork
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
Default Settings After Initial Switch Configuration
The switch is designed for plug-and-play operation, requiring on ly 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.
Note For information about assigning an IP address by using the browser-based Expre ss Setup program, see
the getting started guide. For information about assigning an IP ad dress by using the CLI-based setup
program, see the hardware installation guide.
