or dual rate dual bucket, by analyzing the parameters. The no command will delete the mode
configuration.
Parameters:
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, in kb, ranging from 1 to 10000000. 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 burst size, in kb, ranging from 1 to 10000000. 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.
conform-action：the actions to take when the CIR is not exceeded, which means the messages are
green, including drop, set-dscp-transmit: change dscp (ranging from 0 to 63), set-prec-transmit:
change TOS (ranging from 0 to 1), transmit: messages will pass without any action.
exceed-action：the actions to take when the CIR is exceeded but PIR isn’t, which means the
messages are yellow, including drop, policed-dscp-transmit: mark down the packets DSCP value,
transmit: messages will pass without any action.
violate-action：the actions to take when the PIR is exceeded, which means the messages are red,
including drop, policed-dscp-transmit: mark down the packets DSCP value, transmit: messages will
pass without any action. Notice: this action only exists in dual bucket mode.
Default:
No aggregation Policer is defined by default; the default action of conform-action is transmit, while
that of exceed-action and violate-action both is drop. show running-config won’t display the default
configurations.
Command mode:
Policy class map configuration Mode
Usage Guide:
The CLI can support both singe bucket and dual bucket configuration, and determine which one to
select by checking whether violate-action 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; if PIR and PBS are configured, the mode is dual
rate dual bucket.
Example:
In the policy class table configuration mode, set the CIR as 1000, CBS as 2000 and the action when
CIR is not exceeded as transmitting the messages after changing DSCP to 23, and the action
triggered by exceeding CIR as transmit without changing the messages.
