| Description | This table contains a set of self-consistent Frame
Relay traffic parameters. It is intended to be used to
create Frame Relay to ATM interworking connections,
hence a ATM traffic service category is also included.
An entry in this table is associated with an
equivalent entry in the ATM traffic descriptor table
(atmTrafficDescrParamTable); the mapping is given by
the object casfTrafficDescrAtmIndex. The agent will
not permit deletion of the associated
atmTrafficDescrEntry while the Frame Relay Traffic
Descriptor entry exists.
When creating an entry in this table, if the value of
casfTrafficDescrAtmIndex is specified, the following
cases are possible:
(a) if no corresponding row exists in
atmTrafficDescrParamTable, the agent will create such
a row with the given index value.
(b) if a corresponding row does exist in
atmTrafficDescrParamTable, the agent compares the
parameter values in casfTrafficDescrEntry and the
corresponding atmTrafficDescrParamEntry. If the two
entries are not equivalent, an error is returned, and
row creation fails.
When creating an entry in this table, if the value of
casfTrafficDescrAtmIndex is not specified, the agent
will assign a value to this object so that it refers
to an equivalent entry in the
atmTrafficDescrParamTable. If such an equivalent
entry does not already exist, the agent will create
one.
The agent creates rows in this table for use with
signaled connections. These are called 'transient'
rows - they disappear when the connection is torn
down, and are not saved in non-volatile memory. By
convention, transient rows usually use high-numbered
index values.
Entries can be deleted by setting the row status to
destroy(6). The agent denies the request if the row
is in use by existing connections. |
