CISCO-WAN-NCDP-MIB by vendor Cisco

CISCO-WAN-NCDP-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 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."

                'ncdpRestructure' indicates that the NCDP entity has changed

                '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.

                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
