Enabling the FCP
Beta Draft Confidential
CBR: CLP 0+1 Enter the maximum length of CBR queues in the card. Once 
the queue length reaches this threshold, all cells are discarded 
until the queue length falls below this threshold. 
This field is active only if the Enable ATM Flow Control 
Processor check box is selected.
If you modify this value, you must then perform a PRAM 
Sync.
CBR: EPD/CLP1 
Discard
Enter the discard threshold for CBR queues for the card. 
Once the queue length reaches this threshold, all circuits in 
the QoS class discard cells using CLP1 discard or EPD 
(depending on the circuit definition). 
This field is active only if the Enable ATM Flow Control 
Processor check box is selected.
If you modify this value, you must then perform a PRAM 
Sync.
VBR Real Time: CLP 
0+1
Enter the maximum length of VBR-RT queues for the card. 
Once the queue length reaches this threshold, all cells are 
discarded until the queue length falls below this threshold.
This field is active only if the Enable ATM Flow Control 
Processor check box is selected.
If you modify this value, you must then perform a PRAM 
Sync.
VBR Real Time: 
EPD/CLP1 Discard
Enter the discard threshold for VBR-RT queues for the card. 
Once the queue length reaches this threshold, all circuits in 
the QoS class discard cells using CLP1 discard or EPD 
(depending on the circuit definition). 
This field is active only if the Enable ATM Flow Control 
Processor check box is selected.
If you modify this value, you must then perform a PRAM 
Sync.
VBR Non Real Time: 
CLP 0+1
Enter the maximum length of VBR-NRT queues for the card. 
Once the queue length reaches this threshold, all cells are 
discarded until the queue length falls below this threshold.
This field is active only if the Enable ATM Flow Control 
Processor box is selected.
If you modify this value, you must then perform a PRAM 
Sync.
