The rate cannot exceed the configured interface speed.
Committed Burst Size (BC) – Burst in bytes.
■
(Range: 0-16000000 at a granularity of 4k bytes)
Excess Burst Size (BE) – Burst in excess of committed burst size.
■
(Range: 0-16000000 at a granularity of 4k bytes)
Conform – Specifies that traffic conforming to the maximum rate (CIR)
■
will be transmitted without any change to the DSCP service level.
Transmit – Transmits in-conformance traffic without any
■
change to the DSCP service level.
Exceed – Specifies whether traffic that exceeds the maximum rate (CIR)
■
but is within the excess burst size (BE) will be dropped or the DSCP
service level will be reduced.
Set IP DSCP – Decreases DSCP priority for out of
■
conformance traffic. (Range: 0-63)
Drop – Drops out of conformance traffic.
■
Violate – Specifies whether the traffic that exceeds the excess burst
■
size (BE) will be dropped or the DSCP service level will be reduced.
Set IP DSCP – Decreases DSCP priority for out of
■
conformance traffic. (Range: 0-63)
Drop – Drops out of conformance traffic.
■
trTCM (Police Meter) – Defines the committed information rate (CIR, or
■
maximum throughput), peak information rate (PIR), and their associated
burst sizes – committed burst size (BC, or burst rate) and peak burst size
(BP), and the action to take for traffic conforming to the maximum
throughput, exceeding the maximum throughput but within the peak
information rate, or exceeding the peak information rate. In addition to the
actions defined by this command to transmit, remark the DSCP service
value, or drop a packet, the switch will also mark the two color bits used to
set the drop precedence of a packet for Random Early Detection.
The color modes include "Color-Blind" which assumes that the packet
stream is uncolored, and "Color-Aware" which assumes that the incoming
packets are pre-colored. The functional differences between these modes
is described at the beginning of this section under "trTCM Police Meter. "
Committed Information Rate (CIR) – Rate in kilobits per second.
■
(Range: 0-10000000 kbps at a granularity of 64 kbps or maximum port
speed, whichever is lower)
The rate cannot exceed the configured interface speed.
