Establish the traffic policing style for the specified
class. The simple form of the police command uses
a single data rate and burst size, resulting in two
outcomes: conform and nonconform.
•
datarate
— Data rate in kilobits per second (kbps).
(Range: 1–4294967295)
•
burstsize
— Burst size in Kbps (Range: 1–128)
• conform action — Indicates what happens when
the packet is conforming to the policing rule: it
could be dropped, it could have its COS modified,
it could have its IP precedence modified, or it
could have its DSCP modified. The same actions
are available for packets that do not conform to the
policing rule.
•
cos
— Class of Service value. (Range: 0–7)
•
dscpval
— DSCP value. (Range: 0–63 or a keyword
