  19. 19. Supervisor 720 Hardware FeaturesUser Based Rate Limiting (UBRL) Cisco SystemsThree types of Global Flow Masks that can be stored on Sup1a/2 in the Netflow table… Destination-Only IP (default) Source-Destination IP Full-flow (Src IP, Dst IP, Protocol, Src Port, Dst Port) Microflow policing uses full flow BUT ONLY ONE GLOBAL FLOWMASK CAN BE INSTALLED IN THE SYSTEM AT ANY ONE TIME NOW… Sup720 supports 1. Up to 2 flow masks in the system 2. Source only and destination only flow masks in the PFC3 This new facility increases the capacity of Sup720 to store more entries in its Netflow table… Allows different features that use the Netflow table to use different masks (i.e. IOS SLB, NDE, TCP Intercept, Reflexive ACL‟s, WCCP and CBAC)© 2004, Cisco Systems, Inc.

  21. 21. Supervisor 720 Hardware FeaturesBi Directional PIM Cisco SystemsSupport for Bi-Directional PIM in Hardware was announced on the Supervisor 720 and is availableon IOS. This feature adds the same capability on CatOS… (*,G) (*,G) Source RP (*,G) (*,G) (*,G) Receiver Bidir-PIM has unconditional forwarding of source traffic toward the RP upstream on the shared tree, but no registering process for sources as in PIM-SM. These modifications are necessary and sufficient to allow forwarding of traffic in all routers solely based on the (*, G) multicast routing entries. This feature eliminates any source-specific state and allows scaling capability to an arbitrary number of sources.© 2004, Cisco Systems, Inc. All rights reserved. 21

  36. 36. IOS Architecture Cisco Systems The Multilayer Switch Feature Card (MSFC3) on the Supervisor 720 contains both the Route Processor (RP) and the Switch Processor (SP)… Both the RP and the SP have their SP Bootflash RP Bootflash own set of Flash memory (referred to as bootflash) Switch Processor Route Processor© 2004, Cisco Systems, Inc. All rights reserved. 36
  37. 37. IOS ArchitectureSwitch Processor (SP) Cisco Systems Both the RP and SP perform distinct functions during both the booting of the operating system and the ongoing operation of the switch… The Switch Processor is physically located MSFC3 on the MSFC Logically considered as the Network Switch Management Processor (NMP) Processor (SP) Dedicated CPU, DRAM, Flash and NVRAM - The SP owns the switch at initial boot up before handing over to the RP - The SP runs all layer 2 operations like VTP, Route Spanning Tree, Chassis and Power Processor Management, etc (RP) - Supports other Layer 2 features like CDP, SPAN, Broadcast Suppression, Etherchannel, etc© 2004, Cisco Systems, Inc.
