Modifying ATM Traffic Parameters

You can modify the following traffic parameters for PVCs:

• Peak cell rate (PCR)

• Sustainable cell rate (SCR)

• Maximum burst size (MBS)

For additional information about traffic parameters, see “ATM Traffic Parameters”

on page 1-23.

Setting the PCR

The peak cell rate (PCR) specifies the upper traffic limit, in cells/s, that the ATM

connection can support.

By default, the PCR is set to 4716 cells/s. Table 6-1

lists the valid ranges for each

Bay Networks ATM router.

For additional information about the PCR, see “Using the PCR” on page 1-24.

Using the BCC

To change the PCR value for a PVC, navigate to the PVC prompt (for example,

box; atm/11/1; pvc-service/boston; pvc/11/1/0/32

) and enter:

pcr

integer

is the PCR value that you want the PVC to use.
