Chapter 1      Overview
Features
Quality of Service and Class of Service
Automatic quality of service (auto-QoS) to simplify the deployment of existing QoS features by 
classifying traffic and configuring egress queues
IEEE 802.1p class of service (CoS) with eight priority queues on the Gigabit ports for prioritizing 
mission-critical and time-sensitive traffic from data, voice, and telephony applications
IP Differentiated Services Code Point (IP DSCP) and CoS marking priorities on a per-port basis 
for protecting the performance of mission-critical applications
Flow-based packet classification (classification based on information in the MAC, IP, and 
TCP/UDP headers) for high-performance quality of service at the network edge, allowing for 
differentiated service levels for different types of network traffic and for prioritizing 
mission-critical traffic in the network
Support for IEEE 802.1p CoS scheduling for classification and preferential treatment of 
high-priority voice traffic
Trusted boundary (detect the presence of a Cisco IP Phone, trust the CoS value received, and 
ensure port security. If the IP phone is not detected, disable the trusted setting on the port and 
prevent misuse of a high-priority queue.)
Policing
Traffic-policing policies on the switch port for allocating the amount of the port bandwidth to 
a specific traffic flow 
Policing traffic flows to restrict specific applications or traffic flows to metered, predefined 
rates
Up to 60 policers on ingress Gigabit-capable Ethernet ports 
Granularity of 8 Mbps on 10/100/1000 ports
Out-of-profile markdown for packets that exceed bandwidth utilization limits
Egress Policing and Scheduling of Egress Queues—Four egress queues on all switch ports. Support 
for strict priority and weighted round-robin (WRR) CoS policies
Source IP/Destination IP (SIP/DIP) address routing
Monitoring
Switch LEDs that show port and switch status
Switched Port Analyzer (SPAN) and Remote SPAN (RSPAN) for traffic monitoring on any port or 
VLAN
SPAN support of Intrusion Detection Systems (IDSs) to monitor, repel, and report network security 
violations
Four groups (history, statistics, alarms, and events) of embedded remote monitoring (RMON) agents 
for network monitoring and traffic analysis
MAC address notification for tracking the MAC addresses that the switch has learned or removed
