JUNOSe 7.2.x Policy Management Configuration Guide
100 ! Two-Rate Rate-Limits
If the calculated peak burst value is less than the default peak burst size of 8 KB, 
the default burst size is used. For most configurations this value is probably 
sufficient, making it optional to configure the associated peak burst size.
! During a software upgrade, the peak rate in a rate-limit profile is automatically 
set to 0 if it was nonzero but less than the committed rate before the upgrade. 
! Example
host1(config-rate-limit-profile)#peak-rate 0
! Use the no version to restore the default value, 0.
rate-limit-profile one-rate
! Use to create a rate-limit profile and enter Rate Limit Profile Configuration 
mode, from which you can configure attributes for the rate-limit profile. See 
Table 10 on page 93.
! Use one of the ip, ipv6, l2tp, or mpls keywords in front of the command to 
specify the type of rate-limit profile you want to create or modify. If you do not 
include one of the keywords, the router creates an IP rate-limit profile by 
default. 
! For hierarchical rate limits, do not specify the interface type, but add the 
hierarchical keyword at the end. 
! The color-aware keyword is only supported on hierarchical rate limits.
! If you do not include a one-rate or two-rate keyword, the default is a two-rate 
rate-limit profile.
! If you enter a rate-limit-profile command with the one-rate keyword and then 
type exit, the router creates a rate-limit profile with the default values listed in

NOTE: The JUNOSe software includes the layer 2 headers in the calculations it uses 
to enforce the rates that you specify in rate-limit profiles.
