CISCO-DOCS-EXT-MIB.my
This is the MIB module for the Cisco specific extension objects of Data Over Cable Service, Radio
Frequency interface. There is a standard MIB for Data-Over-Cable Service Interface Specifications
(DOCSIS) and in Cisco, it is called DOCS-IF-MIB. Besides the objects in DOCS-IF-MIB, this MIB
module contains the extension objects to manage the MTA Termination Systems (CMTS).
This MIB module includes objects for the scheduler that supports Quality of Service (QoS) of
MCNS/DOCSIS compliant Radio Frequency (RF) interfaces in cable modem termination systems
(CMTS). The purpose is to let users configure attributes of the schedulers in order to ensure the Quality
of Service and fairness for modem requests according to users' business needs. This MIB also provides
the following:
• objects for various states of the schedulers, allowing you to monitor the schedulers' current status.
• connection status objects for MTAs and Customer Premise Equipment (CPE), to allow you to easily
get the connection status and manage access group information about MTAs and CPE.
• objects for upstream configuration for automated spectrum management in order to mitigate
upstream impairment.
• objects to keep count of the total # of modems, # of registered and # of active modems on the MAC
interface as well as each upstream.
ccsFlapCreateTime The time that this entry was added to the table. If an entry is
removed and then later re-added, there may be a discontinuity
in the counters associated with this entry. This timestamp can
be used to detect those discontinuities.
ccsFlapRowStatus Controls and reflects the status of rows in this table.
When a MTA triggers a flap detector, if an entry does not
already exist for this MTA, and ccsFlapListCurrentSize is less
than ccsFlapListMaxSize, then an entry will be created in this
table. Its instance of this object will be set to active(1). All
flapping modems have the status of active(1).
Active entries are removed from the table after they have not
triggered any additional flap detectors for the period of time
defined in csmFlapAging. Alternatively, setting this instance to
destroy(6) will remove the entry immediately.
To prevent an entry from being aged out, the entry should be set
to notInService(2). The entry will remain in the table until this
instance is set to active by CMTS (and ages out) or destroy.
Upon the next trigger of a flap detector, the entry is reset to
active. An entry in the notInService state can only be set, by the
user, to destroy. A user is not allowed to change a notInService
entry to active.
createAndGo(4) and createAndWait(5) are not supported.
