Define the policer parameters that can be applied to multiple traffic
classes within the same policy map.
•
For
aggregate-policer-name
, specify the name of the aggregate
policer.
•
For
rate-bps,
specify average traffic rate in bits per second
(bps). The range is 8000 to 1000000000.
•
For
cir
cir-bps,
specify the committed information rate in bits
per second. The range is 8000 to 1000000000 bps.
•
(
Optional) For
bc
burst-value
, specify conform burst and the
number of acceptable burst bytes. The range is 8000 to 1000000
bytes.
•
(Optional) For
conform-action
, specify the action to take on
packets that conform to the CIR. The default is to send the
packet.
•
(Optional) For
exceed-action
, specify the action to take on
packets that exceed the CIR. The default is to drop the packet.
See the command reference for this release or the
“Configuring
Input Policy Maps with Individual Policing” section on page 33-39
for definitions of the available keywords.
Step 3
policy-map
policy-map-name
Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
Step 4
class
{
class-map-name
|
class-default
}
Enter a class-map name or
class-default
to match all unclassified
packets, and enter policy-map class configuration mode.
If you enter a class-map name, you must have already created the
class map by using the
class-map
global configuration command.
Step 5
police aggregate
aggregate-policer-name
Apply an aggregate policer to multiple classes in the same policy
map. For
aggregate-policer-name
, enter the name specified in
Step 2.
Step 6
exit
Return to policy-map configuration mode.
Step 7
exit
Return to global configuration mode.
Step 8
interface
interface-id
Enter interface configuration mode for the interface to which you
want to attach the policy.
Step 9
service-policy input
policy-map-name
Attach the policy map (created in Step 3) to the ingress interface.
Step 10
end
Return to privileged EXEC mode.
Step 11
end
Return to privileged EXEC mode.
Step 12
show policer aggregate
[
aggregate-policer-name
]
Verify your entries.
Step 13
copy running-config startup-config
(Optional) Save your entries in the configuration file.
