Description: Defines managed objects for the ISO Connectionless Network Protocol (CLNP) and End System to Intermediate System (ES-IS) protocol management.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CLNS-MIB with a free 30-day trial of IPNetwork Monitor.
What Is CLNS-MIB?
CLNS-MIB is a standard early IETF MIB managing CLNP (Connectionless Network Protocol, OSI Layer 3) forwarding on OSI-capable routers. Its objects cover an intermediate/end-system indicator, default lifetime, inbound receives/header-errors/address-errors, forwarded PDUs, unknown-NLP/ULP counts, inbound discards/delivers, outbound requests/discards/no-routes, reassembly timeout/requests/OKs/failures, segmentation OKs/fails/creates, inbound/outbound option counts, routing discards, and an address table. As a performance/status MIB it lets an administrator watch CLNP forwarding statistics and errors on an OSI-capable router. It is deployed on routers implementing OSI CLNP/CLNS. Engineers can download the CLNS-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CLNS-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.
Supported Devices
- Routers implementing OSI CLNP/CLNS
Monitoring Examples
An administrator checks clnpInDiscards and clnpForwPDUs to diagnose CLNP forwarding problems on an OSI-capable router.
What Can Be Monitored
- CLNP forwarding statistics and errors

Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the clnpMediaToNetTable. That is, it effectively dissassociates the interface identified with said entry from the mapping identified with said entry.

| INT clnpNetToMediaType | 1.3.6.1.3.1.1.23.1.4 | INTEGER | read-write | The type of mapping. Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the clnpNetToMediaTable. That is, it effectively dissassociates the interface identified with said entry from 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 not currently in use. Proper interpretation of such entries requires examination of the relevant clnpNetToMediaType object. |

Setting this object to the value invalid(2) has the effect of invaliding the corresponding entry in the clnpRoutingTable.
