1876 CHAPTER 125: FR QOS CONFIGURATION COMMANDS

cbs

Syntax cbs [ inbound outbound ] committed-burst-size

undo cbs [ inbound outbound ]

View Frame relay class view

Parameters inbound: Sets the committed burst size of the inbound packet, valid only when Frame Relay Traffic Policing (FRTP) is enabled on the interface.

outbound: Sets the committed burst size of the outbound packet, valid only when Frame Relay Traffic Shaping (FRTS) is enabled on the interface.

committed-burst-size: Committed burst size, in bits, ranging from 300 to 16000000. It defaults to 56000 bits.

Description Use the cbs command to set the committed burst size of FR virtual circuit.

Use the undo cbs command to restore the default value.

If the packet direction is not specified in configuration, the parameter will be set in both inbound and outbound directions.

The committed burst size is the packet traffic that is committed to send on a FR network within an interval of Tc. When there is no congestion on the network, the FR network ensures this part of traffic could be sent successfully.

Related commands: ebs, cir allow, cir.

Examples # Set the committed burst size of the FR class named test1 as 64000 bits.

<Sysname> system-view

[Sysname] fr class test1

Syntax cir committed-information-rate

undo cir

View Frame relay class view

Parameters committed-information-rate: The minimum committed information rate (CIR), in

bps, ranging from 1000 to 45000000. It defaults to 56000 bps.

Description Use the cir command to set the CIR of FR virtual circuit.
