bucket, and set the corresponding action for different color packets. The no operation

will delete the mode configuration.

 Parameters: policer_name: the name of aggregation policy;

 bits_per_second: the committed information rate - CIR , in Kbps, ranging from 1 to

10000000;

 normal_burst_bytes: the committed burst size – CBS, in kb, ranging from 1 to 1000000.

When the configured CBS value exceeds the max limit of the chip, configure the

hardware with max number supported by the chip without any CLI prompt;

 maximum_burst_bytes: the peak burst size - PBS, in kb, ranging from 1to 1000000.

When the configured PBS value exceeds the max limit of the chip, configure the

hardware with max number supported by the chip without any CLI prompt. Notice: this

configuration only exists in dual bucket mode;

 pir peak_rate_bps: the peak information rate - PIR, in kbps, ranging from 1to

10000000. Without configuring PIR, the Police works in the single rate dual bucket

mode; otherwise in the dual rate dual bucket mode. Notice: this configuration only

exist in the dual bucket mode.

 exceed-action: the actions to take when the CIR is exceeded but PIR isn’t, which means

the messages are yellow, the default is Drop;

 violate-action: the actions to take when the PIR is exceeded, which means the

messages are red, the default is Drop.

 ACTION:

 drop/transmit: Drop/transmit the packets

 set-internal-priority <intp_value>: Modify the internal priority of the packets

 policied-intp-transmit: Drop the internal priority according to INT-PRIO_TO_INT-PRIO

mapping

 Default: No aggregation Policy is defined by default; the default action of exceed-action

and violate-action both is drop.

 Command mode: Global Mode

 Usage Guide: The CLI can support both singe bucket and dual bucket configuration, and

determine which one by checking whether PIR or PBS is configured. When configuring

with CLI, after configuring CBS, if the action is directly configured, the mode is single

rate single bucket; if only PBS is configured, the mode is single rate dual bucket three

colors; if PIR and PBS are configured, the mode is dual rate dual bucket three colors.

The actions of set and policy selected by policy map are same, the action of policy can

cover the action of the set. Furthermore, If the actions of exceed-action and violate-

action are set-internal-priority in policy, <intp_value> must be same.

 Example: Set the dual bucket mode, CIR is 1000, CBS is 1000, PIR is 20000, PBS is 10000.

The action is policed-intp-transmit when CIR is exceeded but PIR isn’t, which means the

messages are yellow.

 Switch(config)#mls qos aggregate-policy color 10000 1000 20000 10000 exceed-action

policied-intp-transmit
