Setting the SCR

The sustainable cell rate (SCR) is the upper bound on the conforming average rate

of an individual PVC or control VC. The average rate is the number of cells

transmitted over the link divided by the duration of the connection. The duration

of the connection is the total amount of time it takes from connection setup to

connection release.

By default, the SCR is set to 4716 cells/s. Table 6-2

lists the valid ranges for each

Bay Networks ATM router. To disable the SCR, set the value to 0.

For additional information about the SCR, see “Using the SCR” on page 1-25.

Using the BCC

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

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

) and enter:

scr

integer

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

For example, the following command changes the PVC SCR value to 8000:

pvc/11/1/0/32# scr 8000

pvc/11/1/0/32#
