2 MIB OVERVIEW
2.1 DAVID MIB Summary
Every effort has been made to use standard definitions instead of
creating proprietary ones. The MIB used by the DAVID ExpressNet
product line includes the following:
1. The relevant portions of MIB-II, enumerated in section 3 of
this document.
2. DAVID proprietary extensions, defined in sections 4-8 of this
document. This DAVID ExpressNet MIB provides port-level,
module-level, and Concentrator-level status and statistics
information.
Section 9 contains the DAVID trap (alarm) information for DAVID
ExpressNet Intelligent Concentrators. Section 10 lists the object
definitions without the textual descriptions.
The DAVID proprietary extensions are in a separate sub-tree of the MIB
under
iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).david(66).
2.2 DAVID ExpressNet MIB Extensions
The DAVID ExpressNet MIB extensions are divided into the following
groups:
1. Chassis group
Information about the physical enclosure and configuration.
2. Concentrator group
Statistics and status for the overall repeater.
3. Module group
Statistics and status for a single plug-in module.
4. Port group
Statistics and status for a single twisted-pair or AUI port.
5. Management group
Information about the Concentrator's network management.
Following are the object definitions for the groups. The contents of
each group is detailed in the next sections.

END
2.3 Format Of Definitions
Following the conventions of the Structure of Management Information
(SMI), object types are defined using the following five fields:
OBJECT:
A textual name, termed the OBJECT DESCRIPTOR, for the object
type, along with its corresponding OBJECT IDENTIFIER.
Syntax:
The abstract syntax for the object type, presented using ASN.1.
This must resolve to an instance of the ASN.1 type Object
Syntax defined in the SMI.
Definition:
A textual description of the semantics of the object type.
Implementations should ensure that their interpretation of the
object type fulfills this definition, since this MIB is intended
for use in multi-vendor environments. As such, it is vital that
object types have consistent meaning across all machines.
Access:
A keyword, one of "read-only", "read-write", "write-only", or
"not-accessible." Note that this designation specifies the
minimum level of support required.
As a local matter, implementations may support other access
types (e.g. an implementation may elect to permit writing a
DAVID ExpressNet SNMP MIB Page 5
variable marked herein as read-only). Further, protocol-
specific views (e.g. those implied by an SNMP community) may
make further restrictions on access to a variable.
Status:
A keyword, one of "mandatory," "optional," "obsolete," or
"deprecated." Use of "deprecated" implies mandatory status.
2.4 Identification Of Object Instances
This section is quoted from MIB-II.
The names for all object types in the MIB are defined explicitly
either in the Internet-standard MIB or in other documents which
conform to the naming conventions of the SMI. The SMI requires that
conformant management protocols define mechanisms for identifying
individual instances of those object types for a particular network
element.
Each instance of any object type defined in the MIB is identified in
SNMP operations by a unique name called its "variable name." In
general, the name of an SNMP variable is an OBJECT IDENTIFIER of the
form x.y, where x is the name of a non-aggregate object type defined
in the MIB and y is an OBJECT IDENTIFIER fragment that, in a way
specific to the named object type, identifies the desired instance.
This naming strategy admits the fullest exploitation of the semantics
of the powerful SNMP get-next operator, because it assigns names for
related variables so as to be contiguous in the lexicographical
ordering of all variable names known in the MIB.
The type-specific naming of object instances is defined below for a
number of classes of object types. Instances of an object type to
which none of the following naming conventions are applicable are
named by OBJECT IDENTIFIERs of the form x.0, where x is the name of
said object type in the MIB definition.
For example, suppose one wanted to identify an instance of the
variable sysDescr. The object class for sysDescr is:
iso org dod internet mgmt mib system sysDescr
1 3 6 1 2 1 1 1
Hence, the object type, x, would be 1.3.6.1.2.1.1.1 to which is
appended an instance sub-identifier of 0. That is, 1.3.6.1.2.1.1.1.0
identifies the one and only instance of sysDescr.

3 MIB-II OBJECT DEFINITIONS
The DAVID ExpressNet Concentrators implement the following groups from
MIB-II [15]:
1. System
2. Interfaces
3. Address Translation Table
4. IP
5. ICMP
6. UDP
7. SNMP
The groups not implemented are
- the TCP group and the EGP group, because the Concentrators do
not implement the TCP or EGP protocols, and
- the Transmission Group, because it is empty.

4.1 Chassis Slot Configuration Table
4.1.1 ExNetSlotConfigTable Object Type Names - The name of a slot s
is the OBJECT IDENTIFIER value of the form i, where i has the value of
that instance of the object associated with s.
For each object type t, for which the defined name n has a prefix of
exNetSlotConfigEntry, an instance i of t is named by an OBJECT
IDENTIFIER of the form n.s, where s is the name of the slot about
which i represents information.
For example, suppose one wanted to identify the instance of the
variable exNetModuleType associated with slot 2. Accordingly,
exNetModuleType.2 would identify the desired instance.
On the physical Concentrator boxes, the Supervisor Modules are not
numbered and the plug-in modules are numbered from 1 to n-1, where n
is the number of slots in the Concentrator. For the purposes of the
DAVID ExpressNet SNMP MIB, the Supervisor Module is numbered one past
the highest-numbered plug-in module. For example, in a 12-Slot
Concentrator, the plug-in modules are numbered 1-11 and the Supervisor
Module is numbered 12.

6 DAVID EXPRESSNET MODULE GROUP
6.1 Module Table
6.1.1 ExNetModuleTable Object Types Names - The name of the module s
is the OBJECT IDENTIFIER value of the form a, such that a is the value
of that instance of the module associated with s.
For each object type t for which the defined name n has a prefix of
exNetModuleEntry, an instance i of t is named by an OBJECT IDENTIFIER
of the form n.s, where s is the name of the module about which i
represents information.
For example, suppose one wanted to identify an instance of the
variable exNetModuleFCSErrors associated with module 2. Accordingly,
exNetModuleFCSErrors.2 would identify the desired instance.
On the physical Concentrator boxes, the Supervisor Modules are not
numbered and the plug-in modules are numbered from 1 to n-1, where n
is the number of slots in the Concentrator. For the purposes of the
DAVID ExpressNet SNMP MIB, the Supervisor Module is numbered one past
the highest-numbered plug-in module. For example, in a 12-Slot
Concentrator, the plug-in modules are numbered 1-11 and the Supervisor
Module is numbered 12.

7 DAVID EXPRESSNET PORT GROUP
7.1 Ethernet Port Table
7.1.1 ExNetPortTable Object Types Names - The name of the port s is
the OBJECT IDENTIFIER value of the form a.b, such that a.b is the
value of that instance of the port associated with s.
For each object type t for which the defined name n has a prefix of
exNetPortEntry, an instance i of t is named by an OBJECT IDENTIFIER of
the form n.s.p, where s.p is the name of the slot and port about which
i represents information.
For example, suppose one wanted to identify an instance of the
variable exNetPortFCSErrors associated with slot 2 port 1.
Accordingly, exNetPortFCSErrors.2.1 would identify the desired
instance.
On the physical Concentrator boxes, the Supervisor Modules are not
numbered and the plug-in modules are numbered from 1 to n-1, where n
is the number of slots in the Concentrator. For the purposes of the
DAVID ExpressNet SNMP MIB, the Supervisor Module is numbered one past
the highest-numbered plug-in module.
The AUI port on a Supervisor Module is numbered port 1. In a 12-Slot
Concentrator, the AUI port would be slot 12 port 1, and
exNetPortFCSErrors.12.1 would identify the FCS error counts for the
AUI port.

If link status test is enabled, this flag indicates whether
the link is active or inactive. There are several reasons for
an inactive link:
- PC or workstation connected to the MAU has been
turned off
- disrupted link (e.g., wiring problem)
- TP-MAU on the end of the link is missing, dead,
or powered off

9 DAVID EXPRESSNET TRAPS
9.1 Trap PDU
The form of the DAVID ExpressNet Trap-PDU is
Trap-PDU ::=
IMPLICIT SEQUENCE
enterprise -- type of object generating trap
OBJECT IDENTIFIER,
agent-addr -- address of object generating trap
NetworkAddress,
generic-trap -- generic trap type
INTEGER {
coldStart(0),
authenticationFailure(4),
enterpriseSpecific(6)
},
specific-trap -- DAVID-specific
INTEGER {
chassisPsFail(0),
reserved1(1),
moduleFail(2),
modulePsFail(3),
portAutoPartition(4),
portJabbering(5),
reserved6(6),
moduleRecovery(7)
},
time-stamp -- time elapsed between the last
TimeTicks, -- (re)initialization of the network
-- entity and the generation of the trap
variable-bindings -- interesting information
VarBindList
}
The Trap-PDU is generated by a protocol entity only at the request of
the SNMP application entity. The means by which an SNMP application
entity selects the destination addresses of the SNMP application
entities is implementation specific.
Upon receipt of the Trap-PDU, the receiving protocol entity presents
its contents to the SNMP application entity.
The significance of the variable-bindings component of the Trap-PDU is
implementation specific.
9.2 Generic Traps
DAVID ExpressNet SNMP MIB Page 59
9.2.1 The Cold Start Trap - A coldStart(0) trap signifies that the
sending protocol entity is reinitializing itself. As a result, the
agent's configuration or the protocol entity implementation may be
altered.
9.2.2 The Authentication Failure Trap - An authenticationFailure(4)
trap signifies that the sending protocol entity is the addressee of a
protocol message that is not properly authenticated. While
implementations of the SNMP must be capable of generating this trap,
they must also be capable of suppressing the emission of such traps
via an implementation-specific mechanism.
9.2.3 The Enterprise Specific Trap - A enterpriseSpecific(6) trap
signifies that the sending protocol entity recognizes that some
enterprise-specific event has occurred. The specific-trap field
identifies the particular trap that occurred.
9.3 DAVID-Specific Traps
9.3.1 The Chassis Power Supply Failure Trap - A chassisPsFail(0) trap
signifies that the one or more of the voltages in the concentrator's
power supply(ies) has failed.
The exNetChassisPsStatus object identifier variable binding and value
will be returned as interesting information.
9.3.2 The Module Failure Trap - A moduleFail(2) trap signifies that
one of the modules (e.g., a Twisted-Pair Module) has stopped
responding to network management's polls. This could indicate that
the module has been removed from the concentrator with the power on or
that the module has actually failed.
The exNetModuleStatus and exNetModuleSelfTestResult object identifier
variable bindings and values will be returned as interesting
information.
9.3.3 The Module Power Supply Failure Trap - A modulePsFail(3) trap
indicates that one of the module's power supplies has failed.
The exNetModulePsStatus object identifier variable binding and value
will be returned as interesting information.
DAVID ExpressNet SNMP MIB Page 60
9.3.4 The Port AutoPartition Trap - The portAutoPartition(4) trap
indicates that a port has entered the auto-partition state as a result
of 32 consecutive collisions or because the DTE was jabbering.
The exNetPortPartStatus and exNetPortJabberStatus object identifier
variable bindings and values will be returned as interesting
information.
9.3.5 The Port DTE Jabbering Trap - The portJabbering(5) trap
indicates that the DTE connected to the port was jabbering.
The exNetPortJabberStatus object identifier variable binding and value
will be returned as interesting information.
9.3.6 The Module Recovery Trap - A moduleRecovery(7) trap signifies
that one of the modules (e.g., a Twisted-Pair Module) has started
responding to network management's polls. This could indicate that
the module has just been plugged in to the Concentrator, or that the
module had failed and has cleared itself.
The exNetModuleStatus and exNetModuleSelfTestResult object identifier
variable bindings and values will be returned as interesting
information.
