Field Action/Description
Id Identifier for the shaper ID.
Priority A number to identify the priority of this shaper ID.
Scr (cps) The maximum average cell transmission rate that is allowed
over a given period of time on a given circuit. The SCR allows
the network to allocate sufficient resources (but fewer
resources than would be allocated based on PCR) for
guaranteeing that network performance objectives are met.
This parameter applies only to VBR traffic; it does not apply to
CBR or UBR traffic.
Pcr (cps) The PCR ranges between zero (0) and 7. This value represents
the maximum allowed cell transmission rate (expressed in cps).
It defines the shortest time period between cells and provides
the highest guarantee that network performance objectives
(based on CLR) will be met.
Mbs (cell) The maximum number of cells that can be received at the PCR.
MBS allows a burst of cells to arrive at a rate higher than the
SCR. If the burst is larger than anticipated, the additional cells
are either tagged or dropped. This parameter applies only to
VBR traffic; it does not apply to the CBR or UBR traffic.
Type Displays the type for this shaper Id.
