CTRON-FDDI-FNB-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.

                resource instances.  If an instance of a resource is
                not specified, then it is disconnected.

                Each valid configuration is encoded in an ascii string, using 
                a specified format for interpretation.  The connection 
                specifications are in groups of four where each group defines 
                a specific connection configuration.  The terms of a connection
                group is defined as follows:

                        1st - The resource ID as defined by 
                        ctFDDIResourceID.

                        2nd - A specific instance of the physical 
                        resource.  This will be a value between 1 and 
                        ctFDDIResourceNumbInstance for the particular 
                        resource ID in the first term.  If a resource ID
                        has more than one specific resource instance, but
                        the whole resource can be connected, then this 
                        term will have the value '0' to signify all instances 
                        of the resource.

                        3rd - The connection ID for this specific 
                        physical resource.  This value is the same as 
                        ctFDDINMConnectionID, and through the

                        instance of SMT and MAC.

                For example if the value of this object is '1.1.2.2.1.1',
                then it states that resource 1, instance 1 is connected to 
                connection ID 2 and resource 2, instance 1 is connected to 
                connection ID 1 and is inserted into its FDDI ring.

                configuration.  It will specify the connection state of all
                resource instances.  If an instance of a resource is
                not specified, then it is disconnected.

                Each valid configuration is encoded in an ascii string, using
                a specified format for interpretation.  The specific 
                connections are in groups of four where each group defines a 
                specific connection configuration.  The terms of the connection 
                group are defined as follows:

                        1st - Resource ID.  The value is the same as 
                        ctFDDIResourceID for a specific resource entry.

                        2nd - Instance of the resource.  This has a value in
                        the range of 1 to ctFDDIResourceNumbInstance.

                        3rd - Path of the resource as input to the
                        multiplexor.  Paths are specified as 1
                        for the primary ring and 2 for the secondary.

                        4th - This is the multiplexor output channel 
                        that this resource comes out of the multiplexor.
                        This value is the same as a value of ctFDDIMuxOutID.

                        5th - Ring Connectivity.  This sub-identifier
                        describes if the given mux-in resource 
                        (sub-identifiers 1-3) is inserted into the backplane
                        FNB ring.  Valid values are 0 for no 1 for yes.

                So for example a value of 1.1.1.1.0.2.2.2.2.1 is resource 1,
                instance 1 (primary) is on mux-out 1 and it's not inserted;
                resource 2, instance 2 (secondary) is on mux-out 2 and
                is inserted into the backplane.

                If a valid configuration is no connections then this
                object will have a value of '0.0.0.0.0'"
