| docsSubMgt | 1.3.6.1.2.1.125 | | | This is the CMTS centric subscriber management MIB for
DOCSIS-compliant CMTS. It provides the objects to allow a Cable
Modem Termination operator to control the IP addresses and
protocols associated with subscribers' cable modems.

| docsSubMgtObjects | 1.3.6.1.2.1.125.1 | | | |
| docsSubMgtCpeControlTable | 1.3.6.1.2.1.125.1.1 | | not-accessible | This table AUGMENTs the docsIfCmtsCmStatusTable, adding
four WRITEable objects, as well as a read-only object, all of
which reflect the state of subscriber management on a particular
CM. |
| docsSubMgtCpeControlEntry | 1.3.6.1.2.1.125.1.1.1 | | not-accessible | A row in the docsSubMgtCpeControlTable. All values are set
at successful modem registration, either from the system default,
or from objects included in the DOCSIS registration request sent
upstream to the CMTS from the CM. The contents of this entry are
meaningless unless the corresponding docsIfCmtsCmStatusValue (see
reference) is registrationComplete(6). The persistence of this
row is determined solely by the lifespan of the corresponding
docsIfCmtsCmStatusEntry (normally StorageType=volatile). |
| I32 docsSubMgtCpeControlMaxCpeIp | 1.3.6.1.2.1.125.1.1.1.1 | Integer32 | read-write | The number of simultaneous IP addresses permitted behind
the CM. If this is set to zero, all CPE traffic from the CM is
dropped. If the provisioning object corresponding to
docsSubMgtCpeIpTable includes more CPE IP address entries for
this modem than the value of this object, then this object is
set to the count of the number of rows in docsSubMgtCpeIpTable
that have the same docsIfCmtsCmStatusIndex value. (For example,
if the CM has 5 IP addresses specified for it, this value is 5.)
This limit applies to learned and DOCSIS-provisioned entries
but not to entries added through some administrative
process at the CMTS. If not set through DOCSIS provisioning,
this object defaults to docsSubMgtCpeMaxIpDefault. Note that
this object is only meaningful if docsSubMgtCpeControlActive
is true. |
| T/F docsSubMgtCpeControlActive | 1.3.6.1.2.1.125.1.1.1.2 | TruthValue | read-write | Controls the application of subscriber management to
this cable modem. If this is set to true, CMTS-based CPE
control is active, and all the actions required by the various
filter tables and controls apply at the CMTS. If this is set
to false, no subscriber management filtering is done at the
CMTS (but other filters may apply). If not set through DOCSIS
provisioning, this object defaults to
docsSubMgtCpeActiveDefault. |
| T/F docsSubMgtCpeControlLearnable | 1.3.6.1.2.1.125.1.1.1.3 | TruthValue | read-write | Controls whether the CMTS may learn (and pass traffic
for) CPE IP addresses associated with a cable modem. If this is
set to true, the CMTS may learn up to docsSubMgtMaxCpeIp
addresses (less any DOCSIS-provisioned entries) related to this
CM. Those IP addresses are added (by internal process) to the
docsSubMgtCpeIpTable. The nature of the learning mechanism is
not specified here.
If not set through DOCSIS provisioning, this object defaults to
docsSubMgtCpeLearnableDefault. Note that this object is only
meaningful if docsSubMgtCpeControlActive is true. |
| T/F docsSubMgtCpeControlReset | 1.3.6.1.2.1.125.1.1.1.4 | TruthValue | read-write | This object always returns false on read. If this object is
set to true, the rows with 'learned' addresses in
docsSubMgtCpeIpTable for this CM are deleted from that table. |
| TIM docsSubMgtCpeControlLastReset | 1.3.6.1.2.1.125.1.1.1.5 | TimeStamp | read-only | The value of sysUpTime when docsSubMgtCpeControlReset was
last set true. Zero if never reset. |
| I32 docsSubMgtCpeMaxIpDefault | 1.3.6.1.2.1.125.1.2 | Integer32 | read-write | The default value for docsSubMgtCpeControlMaxCpeIp if not
signaled in the DOCSIS Registration request. This value should
be treated as nonvolatile; if set, its value should persist
across device resets. |
| T/F docsSubMgtCpeActiveDefault | 1.3.6.1.2.1.125.1.3 | TruthValue | read-write | The default value for docsSubMgtCpeControlActive if not
signaled in the DOCSIS Registration request. This value should
be treated as nonvolatile; if set, its value should persist
across device resets. |
| T/F docsSubMgtCpeLearnableDefault | 1.3.6.1.2.1.125.1.4 | TruthValue | read-write | The default value for docsSubMgtCpeControlLearnable if not
signaled in the DOCSIS Registration request. This value should
be treated as nonvolatile; if set, its value should persist
across device resets. |
| docsSubMgtCpeIpTable | 1.3.6.1.2.1.125.1.5 | | not-accessible | A table of CPE IP addresses known on a per-CM basis. |
| docsSubMgtCpeIpEntry | 1.3.6.1.2.1.125.1.5.1 | | not-accessible | An entry in the docsSubMgtCpeIpTable. The first index is
the specific modem we're referring to, and the second index is
the specific CPE IP entry. |
| I32 docsSubMgtCpeIpIndex | 1.3.6.1.2.1.125.1.5.1.1 | Integer32 | not-accessible | The index of this CPE IP address relative to the indexed CM.
An entry is created either through the included CPE IP addresses
in the provisioning object, or via learning.
If docsSubMgtCpeControlActive is true and a CMTS receives
an IP packet from a CM that contains a source IP address that
does not match one of the docsSubMgtCpeIpAddr entries for this
CM, one of two things occurs. If the number of entries is less
than docsSubMgtCpeControlMaxCpeIp, the source address is added to
the table and the packet is forwarded. If the number of entries
equals the docsSubMgtCpeControlMaxCpeIp, then the packet is
dropped. |
| IPt docsSubMgtCpeIpAddressType | 1.3.6.1.2.1.125.1.5.1.2 | InetAddressType | read-only | The type of internet address of docsSubMgtCpeIpAddr. |
| IP docsSubMgtCpeIpAddr | 1.3.6.1.2.1.125.1.5.1.3 | InetAddress | read-only | The IP address either set from provisioning or learned via
address gleaning or other forwarding means. See
docsSubMgtCpeIpIndex for the mechanism.
The type of this address is determined by the value of
docsSubMgtCpeIpAddressType. |
| T/F docsSubMgtCpeIpLearned | 1.3.6.1.2.1.125.1.5.1.4 | TruthValue | read-only | If true, this entry was learned from IP packets sent
upstream rather than from the provisioning objects. |
| docsSubMgtCmFilterTable | 1.3.6.1.2.1.125.1.6 | | not-accessible | Binds filter groups to modems, identifying for each modem
the upstream and downstream filter groups that apply to packets
for that modem. Normally, this table reflects the filter group
values signaled by DOCSIS Registration, although values may be
overridden by management action.
For each of the columns in this table, zero is a distinguished
value, indicating that the default filtering action is to be
taken rather than that associated with a filter group number.
Zero is used if the filter group is not signaled by DOCSIS
registration. |
| docsSubMgtCmFilterEntry | 1.3.6.1.2.1.125.1.6.1 | | not-accessible | Binds a filter group to each direction of traffic for a
modem. The filters in this entry apply if
docsSubMgtCpeControlActive is true.
The contents of this entry are meaningless unless the
corresponding docsIfCmtsCmStatusValue (see reference) is
registrationComplete(6). The persistence of this row is
determined solely by the lifespan of the corresponding
docsIfCmtsCmStatusEntry (normally StorageType=volatile). |
| I32 docsSubMgtCmFilterSubDownstream | 1.3.6.1.2.1.125.1.6.1.1 | Integer32 | read-write | The filter group applied to traffic destined for subscribers
attached to the referenced CM. Upon row creation, this is set
either to zero (use default classification, the
diffServClfrElementSpecific=zeroDotZero row of
diffServClfrElementTable) or to the value in the provisioning
object sent upstream from the CM to the CMTS during registration.
The value of this object is the same as that of the filter group
index appearing as docsSubMgtFilterGroupIndex. |
| I32 docsSubMgtCmFilterSubUpstream | 1.3.6.1.2.1.125.1.6.1.2 | Integer32 | read-write | The filter group applied to traffic originating from
subscribers attached to the referenced CM. Upon row creation
this is set to either zero (use default classification, the
diffServClfrElementSpecific=zeroDotZero row of
diffServClfrElementTable), or to the value in the provisioning
object sent upstream from the CM to the CMTS. The value of this
object is the same as that of the filter group index appearing as
docsSubMgtFilterGroupIndex. |
| I32 docsSubMgtCmFilterCmDownstream | 1.3.6.1.2.1.125.1.6.1.3 | Integer32 | read-write | The filter group applied to traffic destined for the
referenced CM itself. Upon row creation this is set either to
zero (use default classification, the
diffServClfrElementSpecific=zeroDotZero row of
diffServClfrElementTable), or to the value in the provisioning
object sent upstream from the CM to the CMTS during registration.
The value of this object is the same as that of the filter group
index appearing as docsSubMgtFilterGroupIndex. |
| I32 docsSubMgtCmFilterCmUpstream | 1.3.6.1.2.1.125.1.6.1.4 | Integer32 | read-write | The filter group applied to traffic originating from the
referenced CM itself. This is set upon row creation to either
zero (use default classification, the
diffServClfrElementSpecific=zeroDotZero row of
diffServClfrElementTable), or to the value in the provisioning
object sent upstream from the CM to the CMTS during registration.
The value of this object is the same as the filter group index
appearing as docsSubMgtFilterGroupIndex. |
| docsSubMgtFilterGroupTable | 1.3.6.1.2.1.125.1.7 | | not-accessible | Provides a collection of referenceable entries to which
diffServClfrElementSpecific refers. This table provides filter
group indices that can be compared with those signaled during
DOCSIS registration. A packet matches an entry from this table
if the packet originated from or is destined to a cable modem
that registered this index as one of its four filter groups
(see docsSubMgtCmFilterTable), and if the packet direction and
MAC address select the use of this index among the four. |
| docsSubMgtFilterGroupEntry | 1.3.6.1.2.1.125.1.7.1 | | not-accessible | An entry only exists if needed by the
diffServClfrElementEntry. A packet matches this entry if the
packet's cable modem registered this index as one of its four
filter groups (see docsSubMgtCmFilterTable) and if the packet
direction and MAC address select the use of this index among
the four. |
| I32 docsSubMgtFilterGroupIndex | 1.3.6.1.2.1.125.1.7.1.1 | Integer32 | read-only | The filter group index, from the set signaled at DOCSIS
Registration. Provides a referenceable entry to which
diffServClfrElementSpecific points. A packet matches this
classifier entry if the packet's cable modem registered this
index value as one of its four filter groups, and if the packet
direction and MAC address select the use of this index among
the four. Because this is the only field in this table, it is
read-only, contrary to the usual SMI custom of making indices
not-accessible.
Note that although zero may be signaled (or defaulted) at DOCSIS
Registration to indicate a default filtering group, no such entry
appears in this table, as diffServClfrElementSpecific will
use a zeroDotZero pointer for that classification. |
