Committed Burst Size Bc (Bits)
Possible Settings: CIR, Other
Default Setting: CIR
Specifies whether the DLCI’s committed burst size will follow the CIR, or whether it will be
entered independently. This value is the maximum amount of data that the service
provider has agreed to accept during the committed rate measurement interval (Tc).
CIR – Uses the value in the CIR (bps) option as the committed burst size (Bc). The Bc and
excess burst size (Be) options are updated when a CIR update is received from the
network switch.
Other – Allows you to specify the committed burst size for the DLCI. When Other is
selected, the Bc and Be values must be manually entered and maintained, as well.
