During a software upgrade, certain values are set as follows:
!
! Committed burst size—Set to 8192 if it was less than that value before the
upgrade
! Peak burst size—Set to 8192 if it was less than that value before the
upgrade
! Peak rate—Set to 0 if it was nonzero but less than the committed rate
before the upgrade
We recommend that you do not configure a committed or peak burst size
NOTE:
smaller than the MTU of the interface. Doing so causes large packets to be
dropped even when they are transmitted at a very low rate.
! Example
host1(config)#ip rate-limit-profile hardlimit9Mb two-rate
Commands that you issue in Rate Limit Profile Configuration mode do not
NOTE:
take effect until you exit from that mode.
! Use the no version to remove a rate-limit profile.
When you configure the rate-limit profile, packets are tagged with a drop
preference. The color-coded tag is added automatically when the committed and
peak burst values for an interface's rate-limit profile are exceeded. The egress
forwarding controller uses the drop preference to determine which packets are
dropped when there is contention for outbound queuing resources within the
E-series router.
