SPVC and SVC Commands
cnfabr
cnfabr
Configures the ABR-specific parameters for an existing SPVC. The connection must be of service type
ABR (in the addcon command, service type=10).

[-icr <Initial cell rate>]
[-adtf <ACR decr. factor>]
[-rdf <Rate decr. factor>]
[-rif <Rate incr. factor>]
[-nrm <Cells per fwd RM>]

Syntax Description
ifNum
The port number of the connection to configure.
vpi
The VPI range for a UNI port endpoint is 0–255. The VPI range for an NNI or VNNI
port endpoint is 0–4095.
vci
The VCI range for a UNI port endpoint is 1–4095. The VCI range for a NNI port
endpoint is 32–65535. For MPLS, the recommended minimum VCI is 35.
-icr
Keyword that specifies the Initial Cell Rate (ICR) in cells per second. This is the rate
at which the source should begin transmitting, and is also the rate at which the source
should resume transmitting after an idle period. The range is 0–4294967295 cells per
second.
-adtf
Keyword that specifies the ACR Decrease Time Factor (ADTF). This is the time
permitted to decrease the cell rate from the RM-cell rate to the Allowed Cell Rate
(ACR) for normal traffic. The range is 1–1023 milliseconds.
-rdf
Keyword that specifies the Rate Decrease Factor (RDF). This is the factor by which
to decrease the Allowed Cell Rate (ACR). RDF is a power of 2 in the range 1/32768
to 1.
-rif
Keyword that specifies the Rate Increase Factor (RIF). This is the factor by which to
increase the Allowed Cell Rate (ACR). RIF is a power of 2 in the range 1/32768 to 1.
