Cisco Catalyst Switch Modules 3110G and 3110X for IBM BladeCenter
7
Policing
z
Traffic-shaping policies on the switch port for managing how much of the port bandwidth
z
should be allocated to a specific traffic flow.
Out-of-profile markdown for packets that exceed bandwidth utilization limits.
z
Ingress queuing and scheduling
z
Two configurable ingress queues for user traffic (one queue can be the priority queue).
z
Weighted tail drop (WTD) as the congestion-avoidance mechanism for managing the queue
z
lengths and providing drop precedences for different traffic classifications.
Shaped round robin (SRR) as the scheduling service for specifying the rate at which packets
z
are sent to the stack or internal ring (sharing is the only supported mode on ingress queues).
Egress queues and scheduling
z
Four egress queues per port.
z
WTD as the congestion-avoidance mechanism for managing the queue lengths and providing
z
drop precedences for different traffic classifications.
SRR as the scheduling service for specifying the rate at which packets are dequeued to the
z
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
z
DSCP and priority queuing for egress traffic.
Egress policing and scheduling of egress queues - four egress queues on all switch ports;
z
support for strict priority and weighted round-robin (WRR) CoS policies.
Layer 3 features
z
HSRP for Layer 3 router redundancy.
z
IP routing protocols for load balancing and for constructing scalable, routed backbones:
z
RIP Versions 1 and 2.
z
OSPF (IP services feature set is required).
z
Enhanced IGRP (EIGRP) (IP services feature set is required).
z
Border Gateway Protocol (BGP) Version 4 (IP services feature set is required).
z
IP routing between VLANs (inter-VLAN routing) for full Layer 3 routing between two or more
z
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
z
is required).
VPNs (IP services feature set is required).
z
Fallback bridging for forwarding non-IP traffic between two or more VLANs (IP services feature
z
set is required).
Static IP routing for manually building a routing table of network path information.
z
Equal-cost routing for load-balancing and redundancy.
z
Internet Control Message Protocol (ICMP) and ICMP Router Discovery Protocol (IRDP) for using
z
router advertisement and router solicitation messages to discover the addresses of routers on
directly-attached subnets.
