(PIM-SM), PIM dense mode (PIM-DM), and PIM sparse-dense mode. The IP Services image is

 

required.

 

● Distance Vector Multicast Routing Protocol (DVMRP) tunneling interconnects 2 multicast-enabled

the number of routes and multicast entries). 468 routed ports are supported per stack.

 

 

Integrated

● Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading

networks simplifies network configuration and improves fault tolerance.

for Bandwidth

● PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the extra capacity inherent

in a redundant design.

 

● IEEE 802.1s Multiple Spanning Tree Protocol allows a spanning-tree instance per VLAN, for Layer 2

 

load sharing on redundant links.

 

● Equal-cost routing facilitates Layer 3 load balancing and redundancy across the stack. The IP

 

Services image is required.

 

● Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private VLAN Edge to

 

minimize broadcasts and maximize available bandwidth.

 

● VLAN1 minimization allows VLAN1 to be disabled on any individual VLAN trunk link.

 

● VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by flooding

 

broadcast traffic only on trunk links required to reach the destination devices.

 

● Internet Group Management Protocol (IGMP) snooping provides fast client joins and leaves of

 

multicast streams and limits bandwidth-intensive video traffic to only the requestors.

 

● Multicast VLAN Registration (MVR) continuously sends multicast streams in a multicast VLAN while

 

isolating the streams from subscriber VLANs for bandwidth and security reasons.

 

● Up to 48 EtherChannel groups are supported per stack.

Scalable

● Cisco StackWise stacking creates a 32-Gbps switch interconnection. Stacking does not require user

ports. Up to 9 units can be stacked together for a maximum of 468 10/100 ports, 468 10/100/1000

 

ports, 108 optical aggregation ports, nine 10 Gigabit Ethernet ports, or any mix thereof. Additional port

 

combinations can be created by stacking together the Cisco Catalyst 3750 Series Switches and the

 

Cisco Catalyst 3750-E Series Switches.

 

 

QoS and Control

 

 

 

Advanced QoS

● Cross-stack QoS allows QoS to be configured across the entire stack.

●802.1p class of service (CoS) and differentiated services code point (DSCP) field classification is provided, using marking and reclassification on a per-packet basis by source and destination IP address, source and destination MAC address, or Layer 4 Transmission Control Protocol/User Datagram Protocol (TCP/UDP) port number.

●Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per- packet basis.

●4 egress queues per port help enable differentiated management of up to 4 traffic types across the stack.

●Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues.

●Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs.

●Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic.

●There is no performance penalty for highly granular QoS capability.
