SNMP MIB Objects

System Group – “sysName” Object (system 5)

This object provides an administratively-assigned name for this managed node.

System Group – “sysLocation” Object (system 6)

This object provides the physical location of this node.

System Group – “sysServices” Object (system 7)

This object provides a value which indicates the set of services that are potentially offered by the DSU/CSU. Only the following values are supported.

Hphysical(1) – Layer 1 functionality for all interfaces.

Hdatalink/subnetwork(2) – Layer 2 functionality (SLIP, PPP) for the COM port.

Hinternet(4) – Layer 3 functionality (IP) for all management links.

Hend-to-end(8) – Layer 4 functionality (UDP) for all management links.

Therefore, set this object to 15 (the sum of 1 + 2 + 4 + 8).

Interface Group, MIB II

The Interfaces Group consists of an object indicating the number of interfaces supported by the unit and an interface table containing an entry for each interface. The DSU/CSU provides an entry in the interface table for the network interface, the DTE Drop/Insert (DSX-1) interface, each of the synchronous data ports (1 or 2), the COM port. The following sections provide clarification for objects contained in the Interface Group where it is not clear how the object definition in MIB II is related to the DSU/CSU.

Interface Group – “ifNumber” Object (interfaces 1)

This variable contains the maximum number of MIB II supported interfaces possible across the 31xx Series product line (9). This is different from the MIB description, which is defined as the number of interfaces on the particular device. This change allows the use of the same ifIndexes across all 31xx Series models.
