Policing
Traffic-shaping policies on the switch port for managing how much of the port bandwidth
should be allocated to a specific traffic flow.
Out-of-profile markdown for packets that exceed bandwidth utilization limits.
Ingress queuing and scheduling
Two configurable ingress queues for user traffic (one queue can be the priority queue).
Weighted tail drop (WTD) as the congestion-avoidance mechanism for managing the queue
lengths and providing drop precedences for different traffic classifications.
Shaped round robin (SRR) as the scheduling service for specifying the rate at which packets
are sent to the stack or internal ring (sharing is the only supported mode on ingress queues).
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).
Automatic quality of service (QoS) voice over IP (VoIP) enhancement for port-based trust of
DSCP and priority queuing for egress traffic.
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.
Layer 3 features
HSRP for Layer 3 router redundancy.
IP routing protocols for load balancing and for constructing scalable, routed backbones:
RIP Versions 1 and 2.
OSPF (IP services feature set is required).
Enhanced IGRP (EIGRP) (IP services feature set is required).
Border Gateway Protocol (BGP) Version 4 (IP services feature set is required).
IP routing between VLANs (inter-VLAN routing) for full Layer 3 routing between two or more
VLANs, allowing each VLAN to maintain its own autonomous data-link domain.
Policy-based routing (PBR) for configuring defined policies for traffic flows (IP services feature set
is required).
VPNs (IP services feature set is required).
Fallback bridging for forwarding non-IP traffic between two or more VLANs (IP services feature
set is required).
Static IP routing for manually building a routing table of network path information.
Equal-cost routing for load-balancing and redundancy.
Internet Control Message Protocol (ICMP) and ICMP Router Discovery Protocol (IRDP) for using
router advertisement and router solicitation messages to discover the addresses of routers on
directly-attached subnets.
