Specifies the action to take on packets describe following:
drop: Drops packet.
set-dscp-transmit new-dscp: Sets the IP differentiated services code
points(DSCP) value and transmits the packet with the new DSCP value
setting.
set-1p-transmit new-cos: Sets the packet COS value and transmits it with the
new CoS value.
transmit: Transmit the packet with no change.
None.
Policy-map Class Configuration Mode.
Level: 15
Use the police sr-tcm command to drop a packet or mark a packet with different
quality of service (QoS) values based on conformance to the service-level
agreement.
The CBS and EBS must be configured so that at least one of them is larger than 0.
The user may specify multiple policing actions for a color packet, but can not
specified contradictory actions at one time. That is, the user can specify action set-
dscp-transmit and set-1p-transmit for a color packet at one time, but can not specify
the action transmit and drop for it.
The algorithm of color classify is described following:
The two token buckets are initially (at time 0) full, that is, the token count Tbc(0) =
CBS and the token count Tbe(0) = EBS. Thereafter, the token counts Tbc and
Tbe are updated bps times per second as follows:
a. If Tbc is less than cbs, Tbc is incremented by one, else
b. if Tbe is less then ebs, Tbe is incremented by one, else
c. neither Tbc nor Tbe is incremented.
When a packet of size B bytes arrives at time t, the following happens:
a. If Tbc(t)-B >= 0, the packet is green and Tbc is decremented by B down to the
minimum value of 0, else
b. If Tbe(t)-B >= 0, the packets is yellow and Tbe is decremented by B down to
the minimum value of 0, else.
c. The packet is red and neither Tc nor Te is decremented.
It is recommended that when the value of the CBS or the EBS is larger than 0, it is
larger than or equal to the size of the largest possible IP packets in the stream.
Only one policer can be bound at one time in the policy-map class configuration
