Introduction
This document describes how to configure ATM traffic shaping on Cisco 2600, 3600, 4000, and 4500 Router Series. The main difference in the support of ATM traffic shaping on the 4000/4500 in comparison to the 2600/3600 router series is that the 4000/4500 platforms support only three service classes while the 2600/3600 Router Series support all traffic types. Other differences are discussed in the Features and Benefits section of this document.
The service classes supported on the 4000/4500 Router Series are:
-
Unspecified Bit Rate (UBR)
-
Non-real time variable bit rate (VBR-nrt)
-
Unspecified Bit Rate Plus (UBR+)
Cisco 2600/3600 Router Series support real time variable bit rate (VBR-rt), Constant Bit Rate (CBR), and Available Bit Rate (ABR) in addition to UBR, VBR-nrt, and UBR+.
The table below shows the Network Modules (NPs) for 2600/3600 Router Series and Network Processor Modules (NPMs) for 4000/4500 Router Series that support ATM traffic shaping.
