Chapter 2 CLI Command Reference

accelerate-packet-drops

Enables the drop-wred-packets-by-hardware mode. This improves performance, but prevents the

application from being able to count all dropped packets. Use the no form to disable the

drop-wred-packets-by-hardware mode, enabling the software to count all dropped packets (at the

expense of some loss of performance).

Syntax Description This command has no arguments or keywords.

Command Default By default, accelerate-packet-drops (the drop-wred-packets-by-hardware mode) is enabled.

Command Modes Interface Linecard Configuration

Command History This table includes the following release-specific history entries:

Usage Guidelines By default, the SCE platform hardware drops WRED packets (packets that are marked to be dropped due

to BW control criteria). However, this presents a problem for the user who needs to know the number of

dropped packets per service.

The user can disable the drop-wred-packets-by-hardware mode. The application can then retrieve the

number of dropped packets for every flow and provide the user with better visibility into the exact

number of dropped packets and their distribution.

Note that counting all dropped packets has a considerable affect on system performance, and therefore,

by default, the drop-wred-packets-by-hardware mode is enabled.

Note The MIB object tpTotalNumWredDiscardedPackets counts dropped packets. The value in this counter is

absolute only in no accelerate-packet-drops mode. When in accelerate-packet-drops mode (default

mode), this MIB counter provides only a relative value indicating the trend of the number of packet

drops, with a factor of approximately 1:6.
