DOCS-IF-MIB.my
This is the MIB Module for MCNS/DOCSIS compliant Radio Frequency (RF) interfaces in MTAs and
CMTSs.
This MIB is composed of the following groups and tables:
• Base Group
– The Downstream Channel table (docsIfDownstreamChannel) describes the attributes of
downstream channels (frequency bands). This table is implemented on both the MTA and the
CMTS.
– The Upstream Channel table (docsIfUpstreamChannel) describes the attributes of attached
upstream channels (frequency bands). This table is implemented on both the CM and the CMTS.
For the CM, only attached channels appear in the table, and the table is read-only.
– The Qos Profile table (docsIfQosProf) describes the attributes for each class of service. The
entries in this table are referenced from the docsIfServiceEntries. They exist as a separate table
in order to reduce redundant information in docsIfServiceTable. This table is implemented at
both the CM and the CMTS. The CM need only maintain entries for the classes of service
referenced by its docsIfServiceTable.
If implemented as read-create in the CMTS, creation of entries in this table is controlled by the
value of docsIfCmtsQosProfilePermissions.
docsDevFilterPolicyPtr This object points to a row in an applicable filter policy table.
Currently, the only standard policy table is
docsDevFilterTosTable. Per the textual convention, this object
points to the first accessible object in the row. E.g. to point to a
row in docsDevFilterTosTable with an index of 21, the value of
this object would be the object identifier docsDevTosStatus.21.
Vendors must adhere to the same convention when adding vendor
specific policy table extensions.
The default upon row creation is a null pointer which results in no
policy action being taken.
TOS Policy Action table objects:
docsDevFilterTosIndex The unique index for this row. There are no ordering requirements
for this table and any valid index may be specified.
docsDevFilterTosStatus The object used to create and delete entries in this table. A row
created by specifying just this object results in a row which
specifies no change to the TOS bits. A row may be created using
either the create-and-go or create-and-wait paradigms. There is
no restriction on the ability to change values in this row while the
row is active.
docsDevFilterTosAndMask This value is bitwise and'd with the matched packet's TOS bits.
docsDevFilterTosOrMask After bitwise and'ing with the above bits, the packet's TOS bits
are bitwise or'd with these bits.
