Quality of Service (QoS)
Advanced classifier-based QoS - classifies traffic using multiple match criteria based on Layer 2, 3
and 4 information; applies QoS policies such as priority level and rate limit to selected traffic on a
per-port or per-VLAN basis
Traffic policing - supports Committed Access Rate (CAR) and line rate
Powerful QoS feature - creates traffic classes based on access control lists (ACL), IEEE 802.1p
precedence, IP, DSCP or Type of Service (ToS) precedence; supports filter, redirect, mirror or remark;
supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR),
weighted fair queuing (WFQ), and weighted random early discard (WRED)
Storm restraint - allows limitation of broadcast, multicast, and unknown unicast traffic rate to cut
down on unwanted broadcast traffic on the network
Resiliency and High
Availability
Intelligent Resilient Framework (IRF) - Creates virtual resilient switching fabrics, where two or more
switches perform as a single Layer 2 switch and Layer 3 router; Switches do not have to be co-
located and can be part of a disaster recovery system; Servers or switches can be attached using
standard LACP for automatic load balancing and high availability; Simplifies network operation by
eliminating Spanning Tree, ECMP and VRRP
Device Link Detection Protocol (DLDP) - Monitors Link connectivity and shuts down ports at both
ends if unidirectional traffic is detected
Rapid Ring Protection Protocol (RRPP) - Connects multiple switches in a high-performance ring using
standard Ethernet technology; traffic can be rerouted around the ring in less than 50 ms upon failure
Smart Link - Allows 50 ms failover between links
Virtual Router Redundancy Protocol (VRRP)
Monitoring and
Diagnostics
OAM (802.3ah) - Detects data link layer problems in the "last mile"; monitors link status between
two devices
CFD (802.1ag) - Connectivity Fault Detection (CFD) provides L2 link OAM mechanism used for link
connectivity detection and fault location
Mirroring - Port mirroring enables traffic on a port to be simultaneously sent to a network analyzer
for monitoring; Flow-based mirroring
