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.
