E Series routers implement a single-rate rate limiter, which you can configure to provide
more efficient service to TCP applications. With the single-rate rate limiter, when the
committed rate is exceeded, the rate limiter drops a single packet and then resumes
transmission up to a configurable burst window. The single, unacknowledged packet
causes TCP to cut its transmission rate in half rather than falling back to its initial window
size.
NOTE: Commands that you issue in Rate Limit Profile Configuration mode
do not take effect until you exit from that mode.
The one-rate rate-limit profile attributes are:
Color aware—Color-aware rate action (only for hierarchical rate limits)
Committed rate—Target rate for a packet flow
Committed burst—Amount of bandwidth allocated to accommodate bursty traffic in
excess of the rate
Excess burst—Amount of bandwidth allocated to accommodate a packet in progress
when the rate is in excess of the burst
Committed action—Drop, transmit, mark (IP and IPv6), or mark-exp (MPLS) when
traffic flow does not exceed the rate; the mark value is not supported for hierarchical
rate limits and the transmit values conditional, unconditional, or final are only supported
on hierarchical rate limits
Conformed action—Drop, transmit, mark (IP and IPv6), or mark-exp (MPLS) when
traffic flow exceeds the rate but not the excess burst; the mark value is not supported
for hierarchical rate limits and the transmit values conditional, unconditional, or final
are only supported on hierarchical rate limits
Exceeded action—Drop, transmit, mark (IP and IPv6), or mark-exp (MPLS) when traffic
flow exceeds the rate; the mark value is not supported for hierarchical rate limits and
the transmit values conditional, unconditional, or final are only supported on hierarchical
rate limits
