What Is SHIVA-AT-MIB?

SHIVA-AT-MIB is a vendor MIB from Shiva Corporation, a maker of dial-up remote access servers (the LanRover product line, later part of Intel), covering configuration of the AppleTalk network-layer protocol on Shiva remote access ports. It defines objects for AppleTalk interface configuration - such as per-port network and node addressing - and for AppleTalk tunneling parameters used to carry AppleTalk traffic encapsulated over IP links. Its monitoring value is software/protocol status on the remote-access device: checking whether an AppleTalk interface is enabled, correctly addressed, and whether a configured tunnel is up, confirms the AppleTalk stack is functioning correctly for dial-in AppleTalk clients. It is one of several Shiva per-protocol MIBs on the same chassis, alongside SHIVA-NW-MIB for NetWare and SHIVA-TPPP-MIB for the underlying PPP layer. It was deployed in legacy AppleTalk-routing remote-access environments on Shiva LanRover dial-up servers, a technology now largely obsolete. Engineers can download the SHIVA-AT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SHIVA-AT-MIB. 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.

Monitoring Examples

Only the IMPORTS clause was captured in the available source excerpt for this module, so no concrete object names beyond that can be cited; based on its stated scope, an administrator would typically check AppleTalk interface configuration objects to confirm the protocol is correctly bound and addressed on a given remote-access port, and check tunnel-parameter objects to confirm an AppleTalk-over-IP tunnel is established.

What Can Be Monitored

AppleTalk interface configuration status
AppleTalk network/node address assignment
AppleTalk tunnel parameters/status

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT tRTMPEntryTimeouts	1.3.6.1.4.1.166.4.2.1	INTEGER	read-only	The number of entries which were removed from routing table because the aging algorithm indicated that they were invalid.
INT tRTMPEntryDeletes	1.3.6.1.4.1.166.4.2.2	INTEGER	read-only	The number of entries which were removed from the routing table for any reason other than aging, for instance, due to a command from a Network Management station.
INT tRTMPEntryEqualReplaces	1.3.6.1.4.1.166.4.2.3	INTEGER	read-only	The number of entries whose route was replaced by another route with the same hop count.
INT tRTMPEntryBetterReplaces	1.3.6.1.4.1.166.4.2.4	INTEGER	read-only	The number of entries whose route was replaced by another route with a lower hop count.
INT tRTMPEntryAdds	1.3.6.1.4.1.166.4.2.5	INTEGER	read-only	The number of new entries which have been added to the table.
INT tRTMPZeroCounters	1.3.6.1.4.1.166.4.2.6	INTEGER	read-write	Writing this variable causes all the RTMP variables in this group to be set to zero.
INT tZIPDeletes	1.3.6.1.4.1.166.4.2.7	INTEGER	read-only	The number of Zones which have been deleted from the Zone Table.
INT tZIPAdds	1.3.6.1.4.1.166.4.2.8	INTEGER	read-only	The number of Zones which have been added to the Zone Table.
INT tZIPZeroCounters	1.3.6.1.4.1.166.4.2.9	INTEGER	read-write	Writing this variable causes all the ZIP variables in this group to be set to zero.
INT tAARPClearCache	1.3.6.1.4.1.166.4.2.10	INTEGER	read-write	Writing this variable clears the AARP Cache.
INT tKIPRoutesValid	1.3.6.1.4.1.166.4.2.11	INTEGER	read-write	This variable can be used to force KIP to reacquire its configuration information.
OCT tNBPDeviceObject	1.3.6.1.4.1.166.4.2.12	OCTET STRING	read-only	The NBP name used to advertise this device's primary NVE on the LAN interface.
OCT tNBPDeviceType	1.3.6.1.4.1.166.4.2.13	OCTET STRING	read-only	The NBP type used to advertise this device's primary NVE on the LAN interface.
OCT tNBPDeviceZone	1.3.6.1.4.1.166.4.2.14	OCTET STRING	read-only	The zone in which this device registers its primary NVE on the LAN interface.
INT tNBPDeviceSocket	1.3.6.1.4.1.166.4.2.15	INTEGER	read-only	The DDP socket number used by the device in NBP Responses for its primary NVE registered on the LAN interface.
OCT tATDialinNetwork	1.3.6.1.4.1.166.4.2.16	OCTET STRING	read-only	The AppleTalk network number in which AppleTalk dialin users appear. When tATDialInPacketDeliveryMode is routing(1) this value corresponds to the configured dialin network number. When tATDialInPacketDeliveryMode is endNodeForwarding(2) this value corresponds to the network number of the LAN interface. Note that when endNodeForwarding(2) it is possible that not all dialin clients have addresses on this network because there may not have been enough available node ids to obtain addresses for all of the clients. In this case another network in the extended range of the LAN interface may be used for the remaining clients' addresses. Ideally this should be a table of clients with their dialin addresses.
OCT tATDialinZone	1.3.6.1.4.1.166.4.2.17	OCTET STRING	read-only	The zone with which tATDialinNetwork is associated.
INT tATRoutingMode	1.3.6.1.4.1.166.4.2.18	INTEGER	read-only	The routing behavior of this device for AppleTalk. If the device is configured as conformingRouter(1) or seedRouter(2) then it will behave as an AppleTalk router on the LAN interface, and will route packets to all interfaces. If it is a conformingRouter(1) then it will learn its configuration for the LAN interface from other routers on that interface's directly-connected network. If it is a seedRouter(2) then it will use the configured LAN interface parameters. If the device is configured as endNode(3) it will behave as an AppleTalk endnode on the LAN interface. other(4) is provided in the event a value is returned which does not match any of the other enumerated values. It is not expected that this will happen.
INT tATDialinPacketDeliveryMode	1.3.6.1.4.1.166.4.2.19	INTEGER	read-only	The method used to deliver packets to and from Appletalk dialin clients. If the device is configured as routing(1) it will use routing tables to deliver packets to and from dialin clients, which will be homed on an internal virtual interface (port). Technically, the value routing(1) is only valid if the device is acting as a router (the value of tATRoutingMode is conformingRouter(1) or seedRouter(2)). If the device is configured to use endNodeForwarding(2) then it will obtain addresses for dialin users in the LAN network range, and will defend those addresses. Packets to and from dialin clients will be forwarded. Technically the device may be configured as endNodeForwarding(2) when tATRoutingMode is any of: conformingRouter(1), seedRouter(2), or endNode(3). other(3) is provided in the event a value is returned which does not match any of the other enumerated values. It is not expected that this will happen.
INT tRTMPEntryTotal	1.3.6.1.4.1.166.4.2.20	INTEGER	read-only	The number of network (range) entries in the device's RTMP Table. This value is not cleared by the tRTMPZeroCounters switch.
INT tZoneTotal	1.3.6.1.4.1.166.4.2.21	INTEGER	read-only	The number of AppleTalk zones for which the device has learned one or more associated nets or net ranges. This value is not cleared by the tZIPZeroCounters switch.
