1. Network Management Specification

6.2ATM Traffic Descriptor Group (RFC 2515)

This table contains a set of self-consistent ATM traffic parameters including the ATM traffic service category, The ATM virtual link tables (that is, VPL and VCL tables), will use this ATM Traffic Descriptor table to assign traffic parameters and service category to the receive and transmit directions of the ATM virtual links (that is, VPLs and VCLs), The ATM VPL or VCL table will indicate a row, in the atmTrafficDescrParamTable using its atmTrafficDescrParamIndex value. The management application can then compare a set of ATM traffic parameters with a single value. If no suitable row(s) in the atmTrafficDescrParamTable exists, the manager must create a new row(s) in this table. If such a row is created, agent checks the sanity of that set of ATM traffic parameter values. The manager may use atmTrafficDescrParamIndexNext in order to obtain a free atmTrafficDescrParamIndex value. When creating a new row, the parameter values will be checked for self-consistency. Predefined/template rows may be supported. A row in the atmTrafficDescrParamTable is deleted by setting the atmTrafficDescrRowStatus to destroy(6). The agent will check whether this row is still in use by any entry of the atmVplTable or atmVclTable. The agent denies the request if the row is still in use.

6.2.0.1“atmServiceCategory” Object (atmTrafficDescrParamEntry 10)

The only valid value for this object is :

•UBR(6) -- unspecified bit rate.

•CBR(2) - constant bit rate

•nrt-VBR(4) - Variable bit rate - non real time

•rt-VBR(3) - Variable bit rate - real time

6.2.1Virtual Channel Link (VCL) Configuration Group (RFC 2515)

This table contains configuration and state information of a bi-directional Virtual Channel Link (VCL) at an ATM interface. This table can be used to create, delete or modify a VCL that is terminated in an ATM host or switch. This table can also be used to create, delete or modify a VCL that is cross-connected to another VCL. ATM Interface Virtual Channel Link (VCL) Table, atmVclEntry is fully supported and contains the following objects:
