ciscoWanNcdpMIB 1.3.6.1.4.1.9.9.223
This MIB module is intended for the management of network clock distribution and the Network Clock Distribution Protocol (NCDP) in Cisco MGX ATM switches. This MIB allows enabling automatic network clock configuration and distribution as well as configuration of manual clock sources. NCDP allows automatic distribution of network clocking sources in the network. A spanning network clock distribution tree is constructed by each node in the network and each node is synchonized to one single 'master' clock reference. A source of network clock for the device may be an oscillator local to the device or a Building Integrated Timing Supply (BITS) port or an interface that supports synchronous clock recovery. An 'index'('cwnClockSourceIndex') is assigned by the NCDP protocol entity in the managed system to identify each available source of network clock on the managed system.

cwnDistributionMethod 1.3.6.1.4.1.9.9.223.1.1.1
The method used to distribute network clock for the device. When the mode of operation is 'ncdp', this device participates in NCDP protocol. A single 'master' clock source will be identified as the clock source for this network as a result. The tables 'cwnAtmSourceTable' and 'cwnAtmInterfaceTable' are used in this mode. When the mode of operation is 'manual', the network clock source is statically configured in this device. The table 'cwnManualSourceTable' is used in this mode.
Status: current Access: read-write
OBJECT-TYPE    
  INTEGER ncdp(1), manual(2)  

cwnNodeStratum 1.3.6.1.4.1.9.9.223.1.1.2
This variable contains the stratum level of the node. This object is only used if the distribution method is 'ncdp'.

  Integer32 3..255  

cwnMessageInterval 1.3.6.1.4.1.9.9.223.1.1.4
The interval at which NCDP configuration PDUs ('Hellos') are to be generated. The message interval directly affects the convergence time of the NCDP algorithm. Convergence time is equal to the max network diameter * message interval + transmission delays + the time a configuration PDU is spent being processed in each device. Thus if transmission delays and processing delays are both close to 0, the convergence time is approximately ( max network diameter * message interval ) milliseconds. This object is only used if the distribution method is 'ncdp'.

  SEQUENCE OF  
    CwnManualSourceEntry

cwnManualSourceEntry 1.3.6.1.4.1.9.9.223.1.3.1.1
When the value of cwnDistributionMethod is 'manual', the managed system uses this table to select a source of network clock for the managed system from the entries in 'cwnClockSourceTable'. The management system uses 'cwnClockSourceIndex' to configure the associated clock source to be a primary, secondary or default clock source. A source of network clock for the device may be an oscillator local to the device or a Building Integrated Timing Supply (BITS) port or an interface that supports synchronous clock recovery. When the managed system initializes it creates a row for the device's default source of network clock, (the entry having 'cwnManualSourcePriority' with value 'default'). Only read operations is allowed on the columnar objects in this row. Other rows are created or destroyed by a management station or through the device's local management interface when a source of network clock is configured or removed. A row is not made active until a valid value for 'cwnManualSourceIndex' is supplied. A management station may perform a write operation on any columnar object while the row is active or not in service.

OBJECT-TYPE    
  SEQUENCE OF  
    CwnAtmSourceEntry

cwnAtmSourceEntry 1.3.6.1.4.1.9.9.223.1.4.1.1
Network clock status for sources of network clock identified by 'cwnClockSourceIndex' and used by the managed system when the value of 'cwnDistributionMethod' is 'ncdp'. The managed device selects one entry in this table to advertise as the best available clock source for the device. Cooperating NCDP protocol entities select the best available clock source among those advertised within the cooperating group and build a clock distribution tree rooted at that clock source. When the value of 'cwnRootClockSource' is used as an index into this table and the indicated clock source has 'cwnAtmSourceBestClockSource' with value 'true' then the indicated clock source is the root of some clock distribution tree. If only one such root exists on all participating devices in the network, then it is the root of a network wide clock distribution tree. When the managed system initializes it creates a row for the device's default source of network clock. This row cannot be destroyed by a management station. Within this row a write operation is only allowed on the 'cwnAtmSourcePriority' object. The status of this row is always active. The default source can always be found by issuing a read operation on the row within 'cwnManualSourceTable' that has 'default' as the value of 'cwnManualSourcePriority'. The other rows are created or destroyed by a management station or through the device's local management interface when a source of network clock is configured or removed. The values of 'cwnAtmSourcePriority', 'cwnAtmSourceStratum' and 'cwnAtmSourcePRSReference' collectively describe a source of network clock. They are the three components of a vector used as an input to the NCDP algorithm to make clock source selection decisions.

cwnAtmSourcePRSReference 1.3.6.1.4.1.9.9.223.1.4.1.1.4
An value that identifies the Primary Reference Source that the network clock available from this source is traceable to if configured as a source of network clock for NCDP. The object takes the value 'internal' when the PRS for this source is an onboard oscillator local to the device. For any other cases the value 'external' is used. If the value of this object is used as a tiebreaker by the algorithm,'external' wins over 'internal'. All 'external' sources of network clock are assumed to be traceable to the same PRS by the NCDP protocol entity.
