cablemodemMgmtBroadcom proprietary MIB for runtime management of cablemodem devices. MODULE-IDENTITY .cableDataMgmtMIBObjects.2 |
cmMgmtBase OBJECT IDENTIFIER .cableDataMgmtMIBObjects.2.1 |
cmNumLLCFiltersSupportedIndicates the number of entries in the docsDevFilterLLCTable
which can be supported on this particular device under current
operating conditions. Note that this is a conservative estimate and
that the device will generally be able to support more filters than
this number returns.
Further note that this number reflects the number of filters supported
if the docsDevFilterIpTable is also simultaneously populated with the
number of filters returned by cmNumIpFiltersSupported. If no IP
filters are configured then the the device can be expected to support
double the number of LLC filters indicated by this object.ro Unsigned32 .cableDataMgmtMIBObjects.2.1.1 |
cmNumIpFiltersSupportedIndicates the number of entries in the docsDevFilterIpTable
which can be supported on this particular device under current
operating conditions. Note that this is a conservative estimate and
that the device will generally be able to support more filters than
this number returns.
Further note that this number reflects the number of filters supported
if the docsDevFilterLLCTable is also simultaneously populated with the
number of filters returned by cmNumLLCFiltersSupported. If no LLC
filters are configured then the the device can be expected to support
double the number of IP filters indicated by this object.ro Unsigned32 .cableDataMgmtMIBObjects.2.1.2 |
cmMiniFirewallEnableSpecifies whether the CM mini-firewall will be enabled, provided the
mini-firewall feature is supported. If the feature is not supported,
this object will always report false(2) and an attempt to set it to
true(1) will be rejected with an incosistentValue error.rw TruthValue (SNMPv2-TC) .cableDataMgmtMIBObjects.2.1.3 |
cmDsdExtendedRetryEnableSpecifies the behavior of the CM with regards to retrying DSD requests
when no reply is received. If set to true(1), the CM will continue
to retry the request until a reply is received or roughly one hour
of time has passed. If set to false(2), the CM will stop retrying
after three retries as required by the DOCSIS specification. Note
that this setting is not persistent across reboot.rw TruthValue (SNMPv2-TC) .cableDataMgmtMIBObjects.2.1.4 |
cmCpeInterfaceFor designs which are not capable of supporting multiple CPE interfaces
simultaneously, this object specifies the interface which will be
used as a CPE interface. Typical settings for such a design would
include ethernet(6) and usb(160). For designs which are capable of
supporting multiple CPE interfaces, this object will always return
other(1).rw IANAifType (IANAifType-MIB) .cableDataMgmtMIBObjects.2.1.5 |
cmResetFactoryDefaultsSetting this object to true(1) will cause the device to reset all
non-volatile settings to their factory default state, and the device
to be rebooted. Note that only dynamic settings will be affected;
permanent settings (MAC addresses, etc) will remain unchanged. When
read, this object always returns false(2).rw TruthValue (SNMPv2-TC) .cableDataMgmtMIBObjects.2.1.6 |
cmTodRefreshIntervalThis object controls the length of time between periodic updates
of system time by way of a Time of Day (ToD) refresh. If set to
0, time of day will not be refreshed. Note that in order to comply
with the DOCSIS requirements for ToD periodocity, a value of 0 should
be used for this object.rw Unsigned32 UNITS "hours" .cableDataMgmtMIBObjects.2.1.7 |
cmDownstreamChannelInfoTableA table describing the characteristics of each downstream channel. An
entry exists in this table for each entry in the ifTable with an
ifType value of docsCableDownstream (128). SEQUENCE OF CmDownstreamChannelInfoEntry .cableDataMgmtMIBObjects.2.1.8 |
cmDownstreamChannelInfoEntryAn entry describing the attributes of a single downstream channel. CmDownstreamChannelInfoEntry .cableDataMgmtMIBObjects.2.1.8.1 |
cmDsChanInfoCodewordErrorRateDownstream Codeword Error Rate. (Errored Codewords / Total CodeWords)ro DisplayString (SNMPv2-TC) .cableDataMgmtMIBObjects.2.1.8.1.1 |
cmDsChanInfoMeanSquareErrorDownstream Mean Square Errorro DisplayString (SNMPv2-TC) .cableDataMgmtMIBObjects.2.1.8.1.2 |
cmIpProvisioningModeThe value of this object determines the mode used by the CM for IP
provisioning.
If set to the default value of mdd(0), the CM will comply with the
DOCSIS 3.0 specification and use the mode identified in the IP
provisioning mode field of the MDD message received from the CMTS.
If set to any other value, the CM will ignore the IP provisioning mode
field of the MDD message and use the mode specified by this object
instead.
If the DOCSIS config file contains a TLV which changes the value of
this object from its current value, the CM will abandon its current IP
settings and restart the IP provisioning and registration process using
the new mode. Setting this object using SNMP does not cause a
restart; in the case of an SNMP set, the new mode will take effect
the next time the CM registers with a CMTS.
Note that this object may also be used to invoke IPv6 or dual-stack
operation when using a pre-DOCSIS 3.0 CMTS, provided the network
hosting the CM is IPv6 capable.
Further note that a CM which does not support IPv6 will always report
ipV4Only(1) for this object, and an attempt to set the object to any
other value will be rejected with an inconsistentValue error.
If this object is set to a value which is incompatible with the
capabilities of the associated CMTS or network, then IP provisioning
may fail. This setting is persistent across reboots.rw Enumeration .cableDataMgmtMIBObjects.2.1.9 |
cmServiceQueueTableThis table describes attributes of each upstream service queue on
a CM. SEQUENCE OF CmServiceQueueEntry .cableDataMgmtMIBObjects.2.1.10 |
cmServiceQueueEntryDescribes the attributes of a single service queue. An entry exists
in this table exists for each service queue. The ifIndex refers to
the entry in the ifTable with an ifType value of
docsCableMaclayer(127). CmServiceQueueEntry .cableDataMgmtMIBObjects.2.1.10.1 |
cmServiceQueueIdIdentifies a service queue for upstream bandwidth. This value is
equal to the SID for this service queue. Integer32 .cableDataMgmtMIBObjects.2.1.10.1.1 |
cmServiceQueueMaxQueueDepthIndicates the maximum number of packets which can be enqueued on this
service queue.ro Gauge32 .cableDataMgmtMIBObjects.2.1.10.1.2 |
cmServiceQueueCurrentQueueDepthIndicates the number of packets currently enqueued on this service
queue.ro Gauge32 .cableDataMgmtMIBObjects.2.1.10.1.3 |
cmFilter OBJECT IDENTIFIER .cableDataMgmtMIBObjects.2.2 |
cmHostIpFilterTableThe table of IP filters to be applied to traffic originating from
or destined to this device. The fields in this table are loosely
based on a subset of the fields in the docsDevFilterIpTable as defined
in the DOCS-CABLE-DEVICE-MIB. The key difference is that the filters
described by the cmHostIpFilterTable are not applied to bridged
traffic, but rather to traffic which is sent from or received by the
cablemodem itself, acting in a role as a host.
This table may be used to restrict certain IP traffic (eg SNMP,
TFTP, telnet, etc.) from being accessible via the CPE and / or HFC
interfaces. Note that all filters will be applied to all IP
addresses associated with this host.
Caution must be exercised in the use of this table. For example, it
is possible to render the device unmanageable if SNMP is prohibited
over both CPE and CM interfaces. SEQUENCE OF CmHostIpFilterEntry .cableDataMgmtMIBObjects.2.2.1 |
cmHostIpFilterEntryAn instance of an IP filter. Entries in the cmHostIpFilterTable are
created and deleted using the cmHostIpFilterStatus object.
Each filter describes a set of criteria against which each IP packet
will be compared. Any packet which matches the filter will be
discarded.
Note that these filters are not applied to bridged traffic, only
to traffic which is sent from or received by the cablemodem itself. CmHostIpFilterEntry .cableDataMgmtMIBObjects.2.2.1.1 |
cmHostIpFilterIndexIdentifies the instance number of this conceptual row. Integer32 .cableDataMgmtMIBObjects.2.2.1.1.1 |
cmHostIpFilterStatusThe status of this conceptual row.
To create a row in this table, a manager must set this object to
either createAndGo(4) or createAndWait(5).
Until instances of all corresponding columns are appropriately
configured, the value of the corresponding instance of the
cmHostIpFilterStatus column is 'notReady'.
In particular, a newly created row cannot be made active until the
corresponding instances of cmHostIpFilterDestPortLow and
cmHostIpFilterDestPortHigh have been set.
Only filters with a status of active(1) will be applied.rw RowStatus (SNMPv2-TC) .cableDataMgmtMIBObjects.2.2.1.1.2 |
cmHostIpFilterStorageTypeThe storage type for this conceptual row. Conceptual rows having the
value 'permanent' need not allow write-access to any columnar objects
in the row.rw StorageType (SNMPv2-TC) .cableDataMgmtMIBObjects.2.2.1.1.3 |
cmHostIpFilterMatchesCounts the number of times this filter was matched.ro Counter32 .cableDataMgmtMIBObjects.2.2.1.1.4 |
cmHostIpFilterInterfacesIdentifies the interfaces to which this filter applies.rw Bits .cableDataMgmtMIBObjects.2.2.1.1.5 |
cmHostIpFilterDirectionDetermines whether the filter is applied to inbound(1) traffic,
outbound(2) traffic, or traffic in both(3) directions.rw Enumeration .cableDataMgmtMIBObjects.2.2.1.1.6 |
cmHostIpFilterDestPortLowThe inclusive lower bound of the transport-layer destination
port range that is to be matched.rw Integer32 .cableDataMgmtMIBObjects.2.2.1.1.7 |
cmHostIpFilterDestPortHighThe inclusive upper bound of the transport-layer destination
port range that is to be matched.rw Integer32 .cableDataMgmtMIBObjects.2.2.1.1.8 |
