Chapter 8. Command Reference 293
ATM SPEED
Sets the speed of the ATM link in kilobits per second.
The default upstream speed is 326 Kb/s. Use this command if the upstream speed exceeds 326 Kb/s. Generally,
your speed value is obtained from your Network Service Provider.
To set the speed in cells per second, use the command atm pcr (page 292)
upstream speed in Kb/S Number provided by the Network Service Provider. The default value for the
upstream speed is 326 Kb/s.
Example:
#atm speed 326
ATM Upstream Rate: 326 Kb/S
REMOTE SETATMTRAFFIC
Sets ATM traffic-shaping on a remote router. ATM traffic-shaping allows the user to set the average rate at which
cells are sent, that is, the Sustained Cell Rate (SCR), to a value lower than the ATM link speed, the Peak Cell Rate
(PCR).
ATM traffic-shaping should be used to allocate bandwidth whenever more than one remote router is defined. In
that case, enter a remote setATMTraffic command for each remote. Thus, if you have five remotes, you need to
enter five commands.
If no ATM traffic values are set, ATM traffic for the remote is shaped using UBR (unspecified bit rate).
If a CBR (constant bit rate) is required, then specify 1 as the Maximum Burst Size (MBS). If a VBR (Variable Bit
Rate) is required, specify a value greater than 1 as the Maximum Burst Size (MBS).
To disable ATM traffic-shaping, use the command remote setATMTraffic 0 0 <remoteName>
SCR Sustained Cell Rate (cells per second).
MBS Maximum Burst Size (cells). For a constant bit rate (CBR), specify 1; for a variable bit rate
(VBR), specify a value greater than 1.
remoteName Name of the remote router (character string).
Examples:
Assuming that the ATM link speed (upstream) is 200 Kb/s 471 cells/s and an average upstream data rate of
20 Kb/s (47 cells/s) is desired, you would issue the following command:
remote setATMtraffic 47 31 HQ
If a constant bit rate (CBR) is required, use the following command:
atm speed [upstream speed in Kb/S]
remote setATMTraffic SCR MBS <remoteName>
