Configuring the Sustainable Cell Rate Margin Factor
The sustained cell rate margin factor determines the aggressiveness of weighting sustainable cell rate
(SCR) compared to peak cell rate (PCR). It uses the connection admission control algorithm in admitting
VBR connections.
To configure the SCR for your ATM switch router, use the following global configuration command:
Note The atm sustained-cell-rate-margin-factor command affects subsequent connections but not
connections that are already established.
Example
The following example shows how to configure the SCR margin factor as 85 percent of maximum:
Switch(config)# atm sustained-cell-rate-margin-factor 85

Displaying the SCR Margin Configuration

To display the SCR margin factor configuration, use the following EXEC command:
Example
The following example shows the SCR margin factor configuration:
Switch> show atm resource
