Chapter 1 Overview
Features
• Out-of-Profile
– Out-of-profile markdown for packets that exceed bandwidth utilization limits
• Ingress queueing 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). 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 bandwidth.
• Automatic quality of service (QoS) voice over IP (VoIP) enhancement for port -based trust of DSCP
and priority queuing for egress traffic
Layer 3 Features
These are the Layer 3 features:
Note Some features noted in this section are available only in the IP services feature set.
• HSRP Version 1 (HSRPv1) and HSRP Version 2 (HSRPv2) for Layer 3 router redundancy
• HSRP for IPv6 (requires the IP services feature set)
• IPv6 default router preference (DRP) for improving the ability of a host to select an appropriate
router.
• IP routing protocols for load balancing and for constructing scalable, routed backbones:
– RIP Versions 1 and 2
– OSPF (requires the IP services feature set)
– HSRP for IPv6 (requires the IP services feature set)
– Enhanced IGRP (EIGRP) (requires the IP services feature set)
– Border Gateway Protocol (BGP) Version 4 (requires the IP services feature set)
• 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
• Multiple VPN routing/forwarding (multi-VRF) instances in customer edge devices to allow service
providers to support multiple virtual private networks (VPNs) and overlap IP addresses between
VPNs (requires the IP services feature set)
