• Routing Parameters
–
Max Cost: Maximum cost size in cells.
–
Frame Discard: If frame-based traffic control is enabled, the EPD threshold determines when to
start discarding an AAL5 frame.
–
Connection Segments: An ABR connection can be divided into separately controlled ABR
segments.
• Features
–
Stats Enable: Enables statistics on a selected connection.
–
CC Enable: Congestion Control Enable. A 22-bit field in the header of the STI cell that is used
to report congestion messages to the source service interface for the ForeSight feature.
• SCT Vc Parameters
–
Service Type: The service type (i.e. CBR, VBR, ABR) to which the parameters apply.
–
Service Category: The service category to which the service type belongs. All service types that
belong to the same service category should be mapped to the same Class of Service Buffer.
Access: read only. Values: 0-65535.
–
Cosb Number: The Class of Service Buffer number associated with the service type. Access:
read-write. Values: 1-16.
–
CAC Treatment: Connection Admission Control. The CAC algorithms that are supported are:
1) lcnCac, 2) eCac-Model A, 3) eCac-Model B, 4) eCac-Model C, 5) eCac-Model D, 6)
eCac-Model E, 7) eCac-Model F, 8) mbBwCac. DEFVAL {2}. Access: read-write. Values:
1-256.
–
UPC Enable: Selectively enables or disables UPC policing on this virtual circuit. Access:
read-write. Values: enableAll(1), enableGera1(2), enable Gera2(3), enable
Gera1WithPktPolicing(5), enable Gera2WithPktPolicing(6).
–
UPC CLP Selection: Usage Parameter Control- Cell Loss Priority Select. Enables or disables
GCRA policing functions on the connection. GCRA1-ENB: Enables GCRA1 only. GCRA 1&2:
Enables both GCRA1 & GCRA2.
–
GCRA No1 Policing Action: Generic Cell Rate Algorithm- Bucket 1. In ATM an algorithm that
defines conformance with respect to the traffic contract of the connection. For each cell arrival
the GCRA determines whether the cell conforms to the traffic contract.
–
GCRA No2 Policing Action: Generic Cell Rate Algorithm- Bucket 2. In ATM an algorithm that
defines conformance with respect to the traffic contract of the connection. For each cell arrival
the GCRA determines whether the cell conforms to the traffic contract.
–
Peak Cell Rate (PCR): The peak (maximum) cell rate for a connection using this service type.
This value is a percentage of the maximum cell rate for the logical interface. 1000000 is equal
to 100%. Range and Units: 0-1000000.
–
Sustained Cell Rate (SCR): The sustained cell rate for a connection using this service type. This
value is a percentage of the maximum cell rate for the logical interface. 1000000 is equal to
100%. Range and Units: 0-1000000.
–
Min Cell Rate (MCR): The minimum cell rate for a connection using this service type. This
value is a percentage of the maximum cell rate for the logical interface. 1000000 is equal to
100%. Range and Units: 0-1000000.
