• Committed Rate
. This value is specified in the range 1 to 4294967295
kilobits-per-second (Kbps).
• Committed Burst Size
. This value is specified in the range 1 to 128 KBytes.
The
committed burst size is used to determine the amount of conforming traffic allowed.
• Conform Action. This lists the actions to be taken on conforming packets according
to the policing metrics, from which one can be selected.
The default is send.
• Violate Action. This lists the actions to be taken on violating packets according to the

• Mark IP DSCP. These packets are marked by Dif
fServ with the specified DSCP
value before being presented to the system forwarding element. This selection
requires that the DSCP field be set.

before being presented to the system forwarding element. This selection requires
that the Mark CoS field be set.
• Mark CoS As Secondary C

not already contain this header, one is inserted.
