CISCO-DOCS-EXT-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

        DESCRIPTION
            "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 Cable Modem 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). And 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. 
             Also this MIB shows various states of the schedulers 
             for users to monitor of the schedulers' current status. 
            
             This MIB module also includes connection status objects
             for cable modems and Customer Premise Equipment (CPE) 
             and the purpose is to let users easily get the connection 
             status and manage access group information about cable 
             modems and CPE.

             This MIB module also includes objects for upstream 
             configuration for automated spectrum management in 
             order to mitigate upstream impairment.

             This MIB module also includes objects to keep count of
             the total # of modems,# of registered and # of active 
             modems on the mac interface as well as each 
             upstream. "

            Upstream supports the following: 
              No rate limiting (1), 
              Bursty 1 second token bucket algorithm(2), 
              Average token usage (CAR-like) algorithm(3),
              Token bucket algorithm with shaping(5).

            Downstream supports the following:
              No rate limiting (1), 
              Bursty 1 second token bucket algorithm(2),
              Average token usage (CAR-like) algorithm(3),
              Weighted excess packet discard algorithm(4), and
              Token bucket algorithm with shaping(5).

            Token bucket algorithm with shaping is the
            default algorithm for upstream if CMTS is in DOCSIS 1.0 mode
            or DOCSIS 1.1 mode.
            

            Bursty 1 second token bucket algorithm is the 
            default algorithm for downstream if the CMTS is in
            DOCSIS 1.0 mode. If it is in DOCSIS 1.1 mode the default
            algorithm for downstream is  Token bucket algorithm with
            shaping .

            Each algorithm is described as below:
              No rate limiting: 
                The rate limiting process is disabled and no checking 
                against the maximum bandwidth allowed. 

              Bursty 1 second token bucket rate limiting algorithm: 
                In this algorithm, at the start of every 1 second interval, 
                a service flow's token usage is reset to 0, and every time 
                the modem for that service flow sends a request (upstream) / 
                packet (downstream) the upstream/downstream bandwidth 
                token usage is incremented by the size of the 
                request/packet sent. As long as the service flow's bandwidth 
                token usage is less than the maximum bandwidth in bits 
                per second (peak rate limit) its QoS service class 
                allows, the request/packets will not be restricted. 
                Once the service flow has sent more than its peak rate in the 
                one second interval, it is prevented from sending more 
                data by rejecting request (upstream) or dropping 
                packets (downstream). This is expected to slow down
                the higher layer sources. The token usage counter gets 
                reset to 0 after the 1 second interval has elapsed. The 
                modem for that service flow is free to send more data up to the 
                peak rate limit in the new 1 second interval that follows.  

              Average token usage (Cisco CAR like) algorithm: 
                This algorithm maintains a continuous average of the 
                burst token usage of a service flow. There is no sudden 
                refilling of tokens every 1 second interval. Every time a 
                request/packet is to be handled, the scheduler tries to see 
                how much time has elapsed since last transmission, and 
                computes the number of tokens accumulated by this service flow 
                at its QoS class peak rate. If burst usage of the service flow 
                is less than tokens accumulated, the burst usage is reset to 0 
                and request/packet is forwarded. If the service flow has 
                accumulated fewer tokens than its burst usage, the burst usage 
                shows an outstanding balance usage after decrementing by the 
                tokens accumulated. In such cases, the request/packet is still 
                forwarded, provided the service flow's outstanding usage does 
                not exceed peak rate limit of its QoS class. If outstanding 
                burst usage exceeds the peak rate of the class, the service 
                flow is given some token credit up to a certain maximum credit 
                limit and the request/packet is forwarded. The request/packet 
                is dropped when outstanding usage exceeds peak rate and maximum 
                credit has been used up by this service flow. This algorithm 
                tracks long term average bandwidth usage of the service flow 
                and controls this average usage at the peak rate limit.

              Weighted excess packet discard algorithm:
                This rate limiting algorithm is only available as an option 
                for downstream rate limiting. The algorithm is to maintain an 
                weighted exponential moving average of the loss rate of a 
                service flow over time. The loss rate, expressed in packets, 
                represents the number of packets that can be sent from this 
                service flow in a one second interval before a packet will 
                be dropped. At every one second interval, the loss rate gets 
                updated using the ratio between the flow peak rate (in bps) 
                in its QoS profile and the service flow actual usage (in bps). 
                If the service flow begins to send more than its peak rate 
                continuously, the number of packets it can send in an one 
                second interval before experiencing a drop will slowly keep 
                reducing until cable modem for that service flow slows down 
                as indicated by actual usage less or equal to the peak rate. 

              Token bucket algorithm with shaping:
                 If there is no QoS class peak rate limit, forward the 
                 request/packet without delay. If there is a QoS peak rate 
                 limit, every time a request/packet is to be handled, the 
                 scheduler determines the number of bandwidth tokens that this 
                 service flow has accumulated over the elapsed time at its 
                 QoS class peak rate and increments the tokens counter of the 
                 service flow accordingly.  The scheduler limits the token 
                 count to the maximum transmit burst (token bucket depth).  
                 If token count is greater than the number of tokens required 
                 to handle current request/packet, decrement token count by 
                 size of request/packet and forwards the request/packet 
                 without delay.  If token count is less than the size of 
                 request/packet, compute the shaping delay time after 
                 which the deficit number of tokens would be available. If 
                 shaping delay time is less than the maximum shaping delay, 
                 decrement tokens count by size of request/packet and 
                 forward this request/packet with the shaping delay in the 
                 shaping delay queue. When the delay time expires, the 
                 request/packet is forwarded. If shaping delay time is 
                 greater than the maximum shaping delay that the subsequent 
                 shaper can handle, the request/packet is dropped. Users can
                 use cdxQosIfRateLimitShpMaxDelay to configure the the maximum 
                 shaping delay and cdxQosIfRateLimitShpGranularity to

            several packets will be in the shaping (delay) queue waiting for

            is that delaying a flows packets (especially TCP flows) for 
            extended periods of time is useless, since the higher protocol 
            layers may assume a packet loss after a certain amount of time.
 
            The maximum shaping delay is only applied to rate limit algorithm: 
            Token bucket algorithm with shaping.  If the rate limit

        DESCRIPTION
            "A CMTS operation entry to instruct a cable modem to move to
             a new downstream and/or upstream channel.
 
             A CMTS operator can use this to initiate an operation
             in CMTS to instruct a cable modem to move to a new
             downstream, or upstream channel or both. 
             
             Each entry consists of the mac address of the cable modem
             to be moved, a new downstream frequency, a new upstream channel 
             id etc..  More than one entries could have for a cable modem,
             so there is a time stamp for each entry to show the time
             when this operation is initiated. 

             A management station wishing to create an entry should
             first generate a pseudo-random serial number to be used
             as the index to this sparse table.  The station should
             then create the associated instance of the row status
             object. It must also, either in the same or in successive
             PDUs, create the associated instance of the command and
             parameter objects. It should also modify the default values
             for any of the parameter objects if the defaults are not
             appropriate.

             Once the appropriate instances of all the command
             objects have been created, either by an explicit SNMP
             set request or by default, the row status should be set
             to active to initiate the operation. Note that this entire
             procedure may be initiated via a single set request which
             specifies a row status  of createAndGo as well as specifies
             valid values for the non-defaulted parameter objects.

             Once an 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 cable modem or time out. 
             In either case, the operation is completed.

             Once the operation is completed, the real result of the 
             operation to the cable modem cannot be known from this table.
             The result of the cable modem's downstream frequency and the 
             upstream channel id can be checked from other MIB tables.  
             For example, docsIfCmtsServiceTable from DOCS-IF-MIB can be 
             used to check whether the cable modem's downstream frequency
             and upstream channel id are changed.  Please note that even
             the CMTS has generated downstream frequency and/or upstream 
             channel override fields in the RNG-RSP message sent to a 
             cable modems, if the cable modem cannot lock the instructed 
             downstream frequency or no upstream channel id could be used, 
             it may reconnect back to the original downstream frequency
             and upstream channel id. 
            
             Once the operation completes, the management station should
             retrieve the values of the cdxCmtsCmChOverState 
             objects of interest, and should then delete the entry.  
             In order to prevent old entries from clogging the table, 
             entries will be aged out, but an entry will never be deleted 
             within 15 minutes of completing. "

-- in automatic noise mitigation.
-- 
-- This group contains tables in CMTS for configuring the upstream

-- CMTS Upstream Channel Table 
--
-- This table contains the additional upstream channel attributes .
-- The additional configurable objects for automated Spectrum Management
-- are the modulation profile and channel width needed for the frequency 
-- hop algorithm used for noise mitigation. 
--
-- Another upstream channel attribute is the number of cable modems.
-- There are three objects to represent each of the following counts:
-- Total: # of modems that were seen on this upstream since boot 
-- Active: # of modems that are active(not online or reset).
-- Registered: # of modems that are registered and online.
--
-- The upstream input power attribute is also reported in the table.
