Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches
Release 5.2, Part Number OL-6484-01 Rev. C0, September 2005
Chapter 5 AXSM Command Reference
cnfabr
cnfabr
Configure ABR—AXSM-E, AXSM-32-T1E1-E, AXSM-XG
Configures the VS/VD-specific parameters for an existing ABR connection. The connection must be of
service type ABR (in the addcon command, service type = 10).
The cnfabr command is available only on the AXSM-E, AXSM-32-T1E1-E, and AXSM-XG. These
cards support ABR virtual source and virtual destination (VS/VD). Therefore, they can generate
resource management (RM) cells and turn them around.
Note With ABR VS/VD, you can specify parameters but leave the VS/VD service disabled. You can later
enable the service and thus activate the previously configured parameters. You can enable VS/VD at the
PNNI port level by using the cnfintfvsvd command on the PXM45.
Warning
Changing connection parameters will result in a momentary loss of traffic.
Warning
Changing routing parameters will not take effect on the slave endpoint of a DAX connection.
Syntax
cnfabr <ifNum><vpi <vci> -icr <Initial cell rate>] -adtf <ACR decr. factor>]
-rdf <Rate decr. factor>] -rif <Rate incr. factor>] -nrm <Cells per fwd RM>]
-trm <Time between fwd RMs>] -cdf <cutoff decrease factor>] -frtt <fix round trip delay>]
-tbe <transient buffer exposure>] -intvsvd <internal vsvd config>] -extvsvd <external vsvd config>]
Syntax Description
ifNum The logical port number of the connection. The ranges are:
AXSM-E: 1–32
AXSM-XG: 1–126
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 1–65535. For MPLS, the recommended minimum VCI is 35.
-icr 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 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 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 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.
