User Manual

Chapter 1. Commands for QoS 15

www.qtech.ru

 normal_burst_bytes: The committed burst size – CBS (Committed Burst Size), in byte,

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 (Peak Burst Size), in byte, 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 information rate – PIR (Peak Information Rate), in kbps,

ranging from 1 to 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 exists in dual bucket mode;

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

messages are red, the default as drop;

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

the messages are yellow, the default as drop.

 ACTION include:

 drop/transmit: Drop/transmit the packets

 set-internal-priority <intp_value> sets the internal priority of the packets

 policied-intp-transmit modifies the internal priority according to intp-to-intp mapping

 Default: No policy action; the default action of exceed-action and violate-action both

are drop.

 Command mode: Policy class map configuration Mode

 Usage Guide: Notice: After the global L3 hardware forwarding function is enabled, the

command is valid.

 The CLI can support both singe bucket and dual bucket configuration, and determine

which one to select 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

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

color; if PIR and PBS are configured, the mode is dual rate dual bucket three color. “set”

and “policy”（policy aggregate） are selected and have the same action in Policy Map,

then the action selected by “policy” will cover the action of “set”.

 If the actions of exceed-action and violate-action are set-internal-priority in policy,

<intp_value> must be same.

 Example: In the policy class table configuration mode, set the CIR as 1000, CBS as 2000

and the action when CIR is exceeded as transmitting the messages after changing intp

to 40.

 Switch(config)#class-map cm

 Switch(config-classmap-cm)#match cos 0

 Switch(config-classmap-cm)#exit

 Switch(config)#policy-map 1
