What Is CISCO-WIRELESS-DOCS-IF-MIB?
CISCO-WIRELESS-DOCS-IF-MIB is a Cisco Systems (Wireless Engineering) proprietary MIB managing MCNS/DOCSIS-compliant RF interfaces on Cisco wireless point-to-multipoint (P2MP) systems consisting of a Head-End (HE) and Subscriber Units (SUs). Its channel table records upstream/downstream frequency and width, mini-slot time-base tick, and sub-channel plan version, a downstream-channel table records sub-channel number/ID/frequency/width/power and modulation-profile index, and an upstream-channel table records the equivalent plus target power and slot size. As a configuration MIB it lets an administrator confirm upstream/downstream channel frequency and power settings on a Cisco wireless broadband access system. It is deployed on Cisco wireless point-to-multipoint broadband access systems (Head-End/Subscriber-Unit). Engineers can download the CISCO-WIRELESS-DOCS-IF-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WIRELESS-DOCS-IF-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Cisco wireless point-to-multipoint broadband access systems (HE/SU)
Monitoring Examples
An administrator checks cwdIfUpChannelTargetPower to confirm a subscriber unit's upstream transmit power is configured correctly before troubleshooting a marginal RF link on a Cisco P2MP wireless system.
What Can Be Monitored
- upstream/downstream RF channel frequency and power configuration

How to Use in IPNetwork Monitor
Example using cwdIfSigQUnerroreds OID:
Select a Cisco wireless point-to-multipoint broadband access system (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cwdIfSigQUnerroreds into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the number of codewords received on this DOCSIS channel without error. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter's growth rate drops noticeably relative to overall traffic on this channel, since a falling proportion of error-free codewords indicates rising RF impairment. Click Finish to create the monitor; you can adjust any parameter later.

| ciscoWirelessDocsIfMib | 1.3.6.1.4.1.9.9.167 | This is the MIB Module for MCNS compliant Radio Frequency (RF) interfaces in wireless point-to-multipoint subscriber units (SU) and wireless Head-end (HE). Glossary : The following terms are used in the MIB definitions below. MCNS : Multimedia Cable Network System P2MP : Point-Multipoint wireless system consisting of Headend (HE) and Subscriber-units (SU). HE : Head-end SU : Subscriber-unit. Attached US channel : The upstream channel on which the SU is transmitting. codeword : Data unit in a FEC (forward error correction) process. OFDM : Orthogonal Frequency Division Multiplexing. ODU : Outdoor unit (antenna). UCD : Upstream Change Descriptor. Cisco Wireless DOCSIS MIB Organization: The Cisco Wireless DOCSIS MIB provides the following categories : * Groups/Tables that are common between HE and SU * Groups/Tables that apply to SU only * Groups/Tables that apply to HE only Groups/Tables that are common between HE and SU o. cwdIfChannelTable This represents the RF channel within which upstream and downstream sub-channels operate. There will one such RF channel per point-to-multipoint interface. A RF channel identifies the portion of the RF spectrum that will be used to create a broadcast domain that will be used for communication. This channel deploys a sub-channel plan, which is used by the upstreams and downstreams. The sub-channel number for a channel is determined based on the number of sub-channels allowed and sub-channel plan version. If the maximum number of sub-channels allowed is 4 and the sub-channel plan version is 1 the spectrum can be sub divided as shown below. reference center frequency of a channel | | v +===============+ | sub 1 | The whole spectrum is used +=======+=======+ so only one sub-channel. +===============+ | 2 | 3 | The spectrum is divided into +===============+ two sub-channels. +===============+ | 2 | 6 | 7 | The spectrum is divided into +===============+ three sub-channels. +===============+ | 4 | 5 | 3 | The spectrum is divided into +===============+ three sub-channels. +===+===+===+===+ | 4 | 5 | 6 | 7 | The spectrum is divided into +===+===+===+===+ 4 sub-channels The above sub-channel planning can be extended to allow maximum number of sub-channels to be 8, 26 etc. The objects in this group are configurable only at the head-end and are read-only at the subscriber end. o. cwdIfDownstreamChannelTable This table contains the configuration information and attributes of downstream channel.

Only the rows that pertain to the upstream used by the subscriber unit will be available at the SU. o. cwdIfQosProfileTable This table describes the attributes of each class of service. The entries in this table are referenced from the cwdIfHeServiceEntries or cwdIfSuServiceEntries. This table is implemented at both the SU and the HE. The SU need only maintain entries for the classes of service referenced by its cwdIfSuServiceTable. o. cwdIfSignalQualityTable At the SU, this table describes the PHY signal quality of downstream channels. At the HE, it describes the PHY signal quality of upstream channels. o. cwdIfModulationTable Describes modulation parameters associated with one or more Upstream or downstream channels.

| cwdIfQosProfileEntry | 1.3.6.1.4.1.9.9.167.1.1.5.1 | not-accessible | Describes the attributes for a single class of service. The row operation for this table is as follows: 1. This table will be implemented as read-only at the SU. SU entries are created by the agent based on information in REG-REQ MAC messages received at the SU from HE or based on information extracted from the TFTP option file 2. Creation of entries in this table is controlled by the value of cwdIfHeQosProfilePermissions. 3. There can be default entries created by the agent at the initialization time. 3. If a table is created by agent, there should only be a single entry for each Class of Service. Multiple entries with the same Class of Service parameters are not recommended as it doesn't add any extra benefit and creates extra processing of a row in the table. 4. You CAN modify a row when it is active provided you have the right cwdIfHeQosProfilePermissions. You can also change the row to notInService and change the values. An entry in this table cannot be removed while it is referenced by an entry in cwdIfSuServiceTable (Subscriber Unit) or cwdIfHeServiceTable (Head-end System). An entry in this table cannot be modified while it is referenced by an entry in cwdIfHeServiceTable. 5.

Any arbitrary integer within the range can be used as index to create a row. | |
