CISCO-ATM-SWITCH-FR-IWF-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.

--
-- Consider two ports 'F' and 'T' on a switch.
-- Suppose 'F' is a frame relay port, connected to a frame relay network or 
-- DTE, and 'T' is an ATM port that is connected to an ATM network or DTE.
-- In this model, the cross-connect between a Frame Relay leg (i.e. DLCI) on
-- port F and an ATM leg (i.e., VPI/VCI) on port 'T' is represented using 
-- another ATM port 'P' that is internal to the switch.  
-- To create a FR-ATM interworking pvc connection,
--	(1) Create a Frame relay connection leg on port F, using the table
--          casfVcEndptTable.
--          The agent will create a corresponding ATM connection leg on
--          the internal ATM port P. The mapping from the FR leg to the 
--          ATM leg on the internal ATM port is created in the casfFAMapTable.
--          The reverse mapping appears in the casfAFMapTable.
--     (2) Create the ATM connection leg on port T, and the cross-connect 
--         between P and T using the usual ATM MIBS, e.g., the AToM MIB.
-- 
-- To create a FR-ATM interworking soft VC connection, initiated from port F,
--      (1) Create a Frame Relay connection leg on port F, using the
--          casfVcEndptTable, also specify the value of the ATM Address
--          of the soft VC target, and the DLCI value to
--          be used at the target. The agent will initiate a soft VC
--          setup, and will also create a corresponding ATM connection
--          leg on the internal ATM port P. The mapping from the FR
--          leg to the ATM leg on the internal ATM port is created in
--          the casfFAMapTable.  The reverse mapping appears in the
--          casfAFMapTable.
--
--      (2) Soft VC parameters, such as the retry interval, can be set
--          on the internal ATM leg.



 -- Frame Relay Traffic Descriptor Table

 casfTrafficDescrTable OBJECT-TYPE 
	SYNTAX  	SEQUENCE OF CasfTrafficDescrEntry 
        MAX-ACCESS  	not-accessible 
        STATUS  	current 
        DESCRIPTION 
               	"This table contains a set of self-consistent Frame
               	 Relay traffic parameters. It is intended to be used to
               	 create Frame Relay to ATM interworking connections,
               	 hence a ATM traffic service category is also included.

	  	 An entry in this table is associated with an
               	 equivalent entry in the ATM traffic descriptor table
               	 (atmTrafficDescrParamTable); the mapping is given by
               	 the object casfTrafficDescrAtmIndex. The agent will
               	 not permit deletion of the associated
               	 atmTrafficDescrEntry while the Frame Relay Traffic 
                 Descriptor entry exists.

		 When creating an entry in this table, if the value of
	         casfTrafficDescrAtmIndex is specified, the following
	         cases are possible:
		 (a) if no corresponding row exists in
	         atmTrafficDescrParamTable, the agent will create such
	         a row with the given index value.
		 (b) if a corresponding row does exist in
	         atmTrafficDescrParamTable, the agent compares the
	         parameter values in casfTrafficDescrEntry and the
	         corresponding atmTrafficDescrParamEntry. If the two
	         entries are not equivalent, an error is returned, and
	         row creation fails.

		 When creating an entry in this table, if the value of
	         casfTrafficDescrAtmIndex is not specified, the agent
	         will assign a value to this object so that it refers
	         to an equivalent entry in the
	         atmTrafficDescrParamTable. If such an equivalent
	         entry does not already exist, the agent will create
	         one.

		 The agent creates rows in this table for use with
		 signaled connections. These are called 'transient'
		 rows - they disappear when the connection is torn
		 down, and are not saved in non-volatile memory. By
		 convention, transient rows usually use high-numbered
		 index values.

		 Entries can be deleted by setting the row status to
	         destroy(6). The agent denies the request if the row
	         is in use by existing connections."

                 end-points of FR-ATM interworking connections on the
                 switch. When an entry is created in this table, the
                 agent creates a corresponding entry in the
                 atmVclTable of ATM-MIB, to represent the
                 configuration on the internal ATM port. The mapping
                 between an entry in this table, and the corresponding
                 entry in the atmVclTable is shown in the
                 casfFAMapTable and the casfAFMapTable.

		 Entries can be created or deleted in this table by an
	         NMS using the casfVcEndptRowStatus object. 
	
		 To create a PVC connection end-point, the value of
	         casfVcEndptConnKind must be 'pvc'.

		 To create a soft VC initiator end-point, set the value of
	         casfVcEndptConnKind to 'spvcInitiator', and specify
	         the value of casfVcEndptSpvcRemoteAddr and
	         casfVcEndptSpvcRemoteType. 

		 If the value of casfVcEndptSpvcRemoteType is
	         'frameRelay', you must also specify the value of
	         casfVcEndptSpvcRemoteDlci. Activating the conceptual
	         row will then cause the agent to attempt to establish
	         a connection to the remote frame relay interface.

                 If the value of casfVcEndptSpvcRemoteType is 'atm',
	         you must specify the values of
	         casfVcEndptSpvcRemoteVpi and
	         casfVcEndptSpvcRemoteVci. Activating the conceptual row
	         will then cause the agent to attempt to establish a
	         connection to the remote ATM interface.

		 The agent creates an entry in this table when an
	         incoming signaling request causes a soft VC
	         connection to be established with a local frame relay
	         interface as the destination. The value of
	         casfVcEndptConnKind in this case will be
	         'spvcTarget'.  Such entries cannot be modified or
