This object is generally intended to be used for the creation of
a temporary inactive upstream row for the purpose of adjusting
the SCDMA channel parameters of an active upstream row.
The recommended procedure is:
1) Create an inactive row through an SNMP SET using createAndWait(5).
Use an ifIndex value outside the operational range of the system.
2) Set the docsIfUpChannelCloneFrom field to the ifIndex value of
the active row whose SCDMA parameters require adjustment.
3) Adjust the SCDMA parameter values using the new temporary inactive
row.
4) Update the active row by setting object docsIfUpChannelUpdate to
TRUE. This SET will fail if the adjusted SCDMA parameters are not
compatible with each other.
5) Delete the temporary row through an SNMP SET using DELETE.
The following restrictions apply to this object:
1) This object must contain a value of active(1) for active rows.
2) Temporary inactive rows must be created using createAndWait(5).
3) The only possible status change of a row created using
createAndWait(5) (ie notInService(2)) is to destroy(6).
These temporary rows must never become active.
4) A status transition from active (1) to destroy (6) is not
permitted. Entries with docsIfUpChannelStatus set to active(1)
are logically linked to a physical interface, not temporarily
created to clone parameters. The Interface MIB (RFC 2863)
ifAdminStatus should be used to take an Upstream Channel offline.
Although this object was created to facilitate SCDMA parameter
adjustment, it may also be used at the vendor's discretion for
non-SCDMA parameter adjustment.
