Description: Digital Equipment Corporation vendor MIB extending FDDI, MIB-II system and interfaces, and bridge objects for DEC ELMS-managed FDDI concentrator and bridge devices

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is DEC-ElanConc?

DEC-ElanConc is a vendor-specific MIB from Digital Equipment Corporation (DEC) for its FDDI-based ELMS-managed concentrator and bridge products, part of DEC's legacy enterprise networking line. It extends standard MIB-II, FDDI, and transparent bridge object groups with DEC private enterprise objects to describe device identity and management structure. As a chassis/interface management MIB it is used to monitor hardware and software status such as device uptime, interface/port operational state, and FDDI ring/bridge health rather than exposing rich sensor telemetry. It depends heavily on the IETF MIB-II (RFC 1213), FDDI SMT, and Bridge MIB standards, layering DEC's private enterprise subtree on top of them. It would typically be deployed on legacy DEC FDDI concentrators and bridges in older enterprise backbone networks that are increasingly rare but may still appear in maintained legacy environments. Network engineers evaluating or troubleshooting this functionality can download the DEC-ElanConc file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DEC-ElanConc. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

DEC FDDI/Ethernet bridge

Monitoring Examples

Because the visible object tree here is limited to the generic mgmt/mib-2/private/enterprises nodes, a monitoring system would walk the standard ifTable/ifEntry (from MIB-II) alongside DEC's private enterprise branch to get per-port operational status and FDDI ring state for each concentrator port. An admin polling ifOperStatus and ifAdminStatus for each interface entry could detect a port that has dropped out of the FDDI ring, while walking the private subtree would reveal any DEC-specific alarm or configuration objects for the concentrator. This is representative of a bridge/concentrator health check pattern common to 1990s-era DEC FDDI gear.

What Can Be Monitored

interface operational status
FDDI ring membership
bridge port state
device identification (sysObjectID)
system uptime

ebrNTPTable	1.3.6.1.4.1.36.2.18.1.4.11.1		not-accessible	A table of Ethernet protocol types which will selectively be translated in such a way as to guarantee that the form in which a packet was received - Ethernet PT or 802.3 with 1042 format and this PT - will be retained across a pair of these bridges.
ebrNTPEntry	1.3.6.1.4.1.36.2.18.1.4.11.1.1		not-accessible	A list of NTP protocol type entries.
INT ebrNTPtype	1.3.6.1.4.1.36.2.18.1.4.11.1.1.1	INTEGER	read-write	A protocol type in the NTP table.

OCT eauthTrapCommunity	1.3.6.1.4.1.36.2.18.1.5.1.1	OCTET STRING	read-write	The community string used in SNMP Trap PDUs.
eauthTrapUserTable	1.3.6.1.4.1.36.2.18.1.5.1.2		not-accessible	A list of addresses to which traps will be sent and associated information.
eauthTrapUserEntry	1.3.6.1.4.1.36.2.18.1.5.1.2.1		not-accessible	Objects containing information for a given trap address.
IP eauthTrapUserAddr	1.3.6.1.4.1.36.2.18.1.5.1.2.1.1	IpAddress	read-write	An IP Address to which all SNMP Trap messages will be sent.
INT eauthTrapUserStatus	1.3.6.1.4.1.36.2.18.1.5.1.2.1.2	INTEGER	read-write	Writing invalid(2) to this object removes the corresponding entry. When read, this object always returns a value of other(1).
OCT eauthReadOnlyCommunity	1.3.6.1.4.1.36.2.18.1.5.1.3	OCTET STRING	read-write	The community string used to identify an SNMP community with access rights of Read-only.
eauthReadOnlyUserTable	1.3.6.1.4.1.36.2.18.1.5.1.4		not-accessible	A list of Read-only users and associated information.
eauthReadOnlyUserEntry	1.3.6.1.4.1.36.2.18.1.5.1.4.1		not-accessible	Objects containing information for a given Read-only user.
IP eauthReadOnlyUserAddr	1.3.6.1.4.1.36.2.18.1.5.1.4.1.1	IpAddress	read-write	An IP Address, or a set of IP addresses, which has Read-only SNMP access to this agent. If this object is used as a wildcard, bits corresponding to the zero bits in the corresponding euthReadOnlyUserMask are treated as don't-care.
OCT eauthReadOnlyUserMask	1.3.6.1.4.1.36.2.18.1.5.1.4.1.2	OCTET STRING	read-write	A 32-bit mask which is applied to (ANDed with) the source IP address of an incoming SNMP message. If the result of the mask is equal to eauthReadOnlyUserAddr, the message is considered to have come from a user who has Read-only access. This allows wildcarding, for example, for all NMS's on a given subnet. For fully specified IP addresses required to be in this community, this mask may be set to all 1's.
INT eauthReadOnlyUserStatus	1.3.6.1.4.1.36.2.18.1.5.1.4.1.3	INTEGER	read-write	Writing invalid(2) to this object removes the corresponding entry. When read, this object always returns a value of other(1).
OCT eauthReadWriteCommunity	1.3.6.1.4.1.36.2.18.1.5.1.5	OCTET STRING	read-write	The community string used to identify an SNMP community with access rights of Read-Write.
eauthReadWriteUserTable	1.3.6.1.4.1.36.2.18.1.5.1.6		not-accessible	A list of Read-Write users and associated information.
eauthReadWriteUserEntry	1.3.6.1.4.1.36.2.18.1.5.1.6.1		not-accessible	Objects containing information for a given Read-Write user.
IP eauthReadWriteUserAddr	1.3.6.1.4.1.36.2.18.1.5.1.6.1.1	IpAddress	read-write	An IP Address, or a set of IP addresses, which has Read-Write SNMP access to this agent. If this object is used as a wildcard, bits corresponding to the zero bits in the corresponding euthReadWriteUserMask are treated as don't-care.
OCT eauthReadWriteUserMask	1.3.6.1.4.1.36.2.18.1.5.1.6.1.2	OCTET STRING	read-write	A 32-bit mask which is applied to (ANDed with) the source IP address of an incoming SNMP message. If the result of the mask is equal to eauthReadWriteUserAddr, the message is considered to have come from a user who has Read-Write access. This allows wildcarding, for example, for all NMS's on a given subnet. For fully specified IP addresses required to be in this community, this mask may be set to all 1's.
INT eauthReadWriteUserStatus	1.3.6.1.4.1.36.2.18.1.5.1.6.1.3	INTEGER	read-write	Writing invalid(2) to this object removes the corresponding entry. When read, this object always returns a value of other(1).
