Parameter: Xmt Sustainable Cell Rate

Path: Configuration Manager > Circuits > Edit Circuits > Edit > MPLS > LDP >

Default VC

Default: 0

Options: 0; 128 to 353207

Function: Specifies the upper limit of the ATM connection conforming average rate on the

transmitting side. The average rate equals the total number of cells transmitted,

divided by the duration of the connection. The default value, 0, indicates that the

transmit SCR is off.

Using the sustainable cell rate (SCR), you can define the future cell flow of a

VC in greater detail than by using only the peak cell rate.

The SCR maps directly to the minimum cell rate (MCR). The MCR defines the

minimum amount of guaranteed bandwidth allowed for the default VC on the

ATM line.

When setting the SCR, keep the following in mind:

• To be useful, the SCR must not exceed the PCR.

• If you know the average rate, set the SCR approximately 10 percent higher

than this value.

• VCs may fail to operate with SCR values lower than 128 cells/s.

• Entering 0 for the SCR turns off this function.

Instructions: After you determine the transmission rate of your ATM device, set the

sustainable cell rate within the specified range. Enter 0 to turn off this function.
