Chapter1 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 appli cations
–
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 polic ies
•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
