Cisco Systems MGX 8230 manual Release 1.1.31, Part Number 78-11215-03 Rev. B0, May

Chapter 6 Card and Service Configuration

ATM Universal Service Module (AUSM)

•port.vpi.vci identifies the connection.

•enable is the enabled/disable for the ForeSight feature: 1=disable, 2=enable.

•fgcra_enabl is the enabled/disable for the Frame-based generic cell rate

ealgorithm: 1=disable, 2=enable.

•	ibs	is the initial burst size in the range 0–5000 cells.
•	pcr	is the peak cell rate. Without IMA, the range is:
		–	T1, 10–3622
		–	E1, 10–4528
		–	clear E1, 10–4830

For IMA, multiply the line rate by the number of links.

•mcr is the minimum cell rate. Without IMA, the range is:

–T1, 0–3622

–E1, 0–4528

–clear E1, 0–4830

For IMA, multiply the line rate by the number of links.

• icr is the initial cell rate. Without IMA, the range is as follows:

–T1, 0–3622

–E1, 0–4528

–clear E1, 0–4830

For IMA, multiply the line rate by the number of links.

Step 4 Use cnfconstdabr to configure the parameters for a standard ABR (TM 4.0 compliant).

cnfconstdabr <Chan_Num ABRType> <mcr> <pcr> <icr> <rif> <rdf> <nrm> <trm> <tbe> <frtt> <adtf> <cdf>.

Please note the following:

•Standard ABR is a connection-level feature that requires the Rate Control Feature to be enabled on the card.

•Virtual Source/Virtual Destination behavior (VS/VD) is not supported.

•Standard ABR does not support Explicit Rate (ER) marking of RM cells.

•cnfconabrrates can be used to modify the rates:

Usage: cnfconabrrates <Port.Vpi.Vci/Chan_Num> <mcr> <pcr> <icr>

•cnfconabrparams can be used to modify the parameters:

Usage: cnfconabrparams <Port.Vpi.Vci/Chan_num> <ABRType> <rif> <rdf> <nrm> <trm> <tbe> <rtt> <adtf>

•rif and rdf values for a Standard ABR connection need to be configured to be <= PCR for the connection.
