Configuring QoS
Step 6
police { rate-bps | cir cir-bps } Define a policer for the priority class of traffic.
•
For rate-bps, specify average traffic rate in bits per second
(bps). The range is 64000 to 1000000000.
Note When you use the police command with the priority
command in an output policy, the police rate range and the
CIR
range is 64000 to 1000000000 bps, even though the
range that appears in the CLI help is 8000 to 1000000000.
You cannot attach an output service policy with an
out-of-range rate.
• For cir cir-bps, specify a committed information rate (CIR)
in bits per second (bps). The range is 64000 to 1000000000.
Note
Although visible in the command-line help string, the
burst-size option is not supported in output policy maps.
You cannot attach an output service policy map that has a
configured burst size.
Step 7 conform-action [ transmit ] (Optional) Enter the action to be taken on packets that conform to
the CIR. If no action is entered, the default action is to send the
packet.
Note You can enter a single conform-action as part of the
command string following the
police command. You can
also enter a carriage return after the police command and
enter policy-map class police configuration mode to enter
the conform-action. When the
police command is
configured with priority in an output policy map, only the
default conform-action of
transmit is supported.
Although visible in the command-line help string, the
other police conform actions are not supported in output
policy maps.
Step 8 exceed-action [ drop ] (Optional) Enter the action to be taken for packets that do not
conform to the CIR. If no action is entered, the default action is to
drop the packet.
Note You can enter a single exceed-action as part of the
command string following the
police command. You can
also enter a carriage return after the police command and
enter policy-map class police configuration mode to enter
the exceed-action. When the
police command is
configured with priority in an output policy map, only the
default exceed-action of
drop is supported. Although
visible in the command-line help string, the other police
exceed actions are not supported in output policy maps.
Step 9
exit Exit policy-map class configuration mode for the priority class.
Step 10 class class-map-name Enter the name of the first nonpriority class, and enter policy-map
class configuration mode for that class.
