Cisco uBR7246vxr MIBs
DOCS-CABLE-DEVICE-MIB.my
This is the MIB Module for MCNS-compliant MTAs and cable-modem termination systems.
• The Access table (docsDevNmAccessTable) provides one level of security for access to the device
by network management stations. The table controls access to SNMP objects by network
management stations. If the table is empty, access to SNMP objects is unrestricted. This table exists
only on SNMPv1 or v2c agents and does not exist on SNMPv3 agents (see the conformance section
for details). Specifically, for v3 agents, the appropriate MIBs and security models apply in lieu of
this table.
Entries in the table are ordered by docsDevNmAccessIndex. The first matching entry (e.g. matching
IP address and community string) is used to derive access.
Note that access is also constrained by the community strings and any vendor-specific security.
• The Server Access group (docsDevServer) describes server access and parameters used for initial
provisioning and bootstrapping.
• The Event Reporting group (docsDevEv) controls the reporting of the various classes of events.
This group includes:
– the Control table in which a combination of logging and reporting mechanisms may be chosen
for each event priority. The mapping of event types to priorities is vendor-dependent. Vendors
may also choose to allow the user to control that mapping through proprietary means.
– the Events table (DocsDevEvent), which contains a log of network and device events that may
be of interest in fault isolation and troubleshooting.
Multiple sequential identical events are represented by incrementing docsDevEvCounts and
setting docsDevEvLastTime to the current time rather than creating multiple rows.
Entries are created with the first occurrence of an event. docsDevEvControl can be used to clear
the table. Individual events can not be deleted.
cdxCmtsCmOnOffNotification This notification indicates that the MTA is coming online and
going offline. A notification is sent from the CMTS for a
MTA status changing to online or offline within the interval
specified in cdxCmtsCmOnOffTrapInterval.
cdxCmtsCmChOverNotification This notification is sent at the completion of a CMTS channel
override operation if cdxCmtsCmChOverTrapOnCompletion
is true in the original entry.
Once a channel override operation has been activated, it
cannot be stopped. That is, it will run until either the CMTS
has generated downstream frequency and/or upstream
channel override fields in the RNG-RSP message sent to a
MTA or cdxCmtsCmChOverTimeExpiration time expired. In
either case, the operation is completed. State in the
cdxCmtsCmChOverState object will tell in which condition
the operation is completed.
