ECX25EXT-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.

	      -- The status of a table entry.
	      --
	      -- Setting this object to the value invalid(4) has the
	      -- effect of invalidating the corresponding entry.
	      -- That is, it effectively disassociates the mapping
	      -- identified with said entry.
	      -- It is an implementation-specific matter as to whether
	      -- the agent removes an invalidated entry from the table.
	      -- Accordingly, management stations must be prepared to
	      -- receive tabular information from agents that corresponds
	      -- to entries currently not in use.  Proper
	      -- interpretation of such entries requires examination
	      -- of the relevant EntryStatus object.
	      --
	      -- An existing instance of this object cannot be set to
	      -- createRequest(2).  This object may only be set to
	      -- createRequest(2) when this instance is created.  When
	      -- this object is created, the agent may wish to create
	      -- supplemental object instances to complete a conceptual
	      -- row in this table.  Immediately after completing the
	      -- create operation, the agent must set this object to
	      -- underCreation(3).
	      --
	      -- Entries shall exist in the underCreation(3) state until
	      -- the management station is finished configuring the
	      -- entry and sets this object to valid(1) or aborts,
	      -- setting this object to invalid(4).  If the agent
	      -- determines that an entry has been in the
	      -- underCreation(3) state for an abnormally long time,
	      -- it may decide that the management station has
	      -- crashed.  If the agent makes this decision,
	      -- it may set this object to invalid(4) to reclaim the
	      -- entry.  A prudent agent will understand that the
	      -- management station may need to wait for human input
	      -- and will allow for that possibility in its
	      -- determination of this abnormally long period.

	  -- Support of the X25 subtree and all subtrees under it

			  "This object reports the current status of
			  the circuit.

			  An existing instance of this object can only
			  be set to startClear, startPvcResetting, or
			  invalid.  An instance with the value calling
			  or open can only be set to startClear and
			  that action will start clearing the circuit.
			  An instance with the value PVC can only be
			  set to startPvcResetting or invalid and that
			  action resets the PVC or deletes the circuit
			  respectively.  The values startClear or
			  startPvcResetting will never be returned by
			  an agent.  An attempt to set the status of
			  an existing instance to a value other than
			  one of these values will result in an error.

			  A non-existing instance can be set to PVC to
			  create a PVC if the implementation supports
			  dynamic creation of PVCs.  Some
			  implementations may only allow creation and
			  deletion of PVCs if the interface is down.
			  Since the instance identifier will supply
			  the PLE index and the channel number,
			  setting this object alone supplies
			  sufficient information to create the
			  instance.  All the DEFVAL clauses for the
			  other objects of this table are appropriate
			  for creating a PVC; PLEs creating entries
			  for placed or accepted calls will use values
			  appropriate for the call rather than the
			  value of the DEFVAL clause.  Two managers
			  trying to create the same PVC can determine
			  from the return code which manager succeeded
			  and which failed (the failing manager fails
			  because it can not set a value of PVC for an
			  existing object).


			  An entry in the closed or invalid state may
			  be deleted or reused at the agent's
			  convence.  If the entry is kept in the
			  closed state, the values of the parameters
			  associated with the entry must be correct.
			  Closed implies the values in the circuit
			  table are correct.

			  The value of invalid indicates the other
			  values in the table are invalid.  Many
			  agents may never return a value of invalid
			  because they dynamically allocate and free
			  unused table entries.  An agent for a
			  statically configured systems can return
			  invalid to indicate the entry has not yet
			  been used so the counters contain no
			  information."
