gvcIfDlciSpCommittedBurstSize
General Vc Interface Dlci Sp Committed Burst Size
This attribute specifies the committed burst size (bc) in bits. bc is the amount of data that a network agrees to transfer under normal conditions over a measurement interval (t). Data marked DE=1 is not accounted for in bc. This attribute is ignored when rateEnforcement is off. If rateEnforcement is on and this attribute is 0, cir must also be 0.
