Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter6 Card and Service Configuration
ATM Universal Service Module (AUSM)
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.
• port.vpi.vci identifies the connection.
• enable is the enabled/disable for the ForeSight feature:
1=disable, 2=enable.
• fgcra_enabl
e
is the enabled/disable for the Frame-based generic cell rate
algorithm: 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.
