System Group, MIB II

The System Group objects are fully supported by the

E1 NTU. The following sections provide clarification for objects contained in the System Group where it is not otherwise clear how the object definition in MIB II is related to the E1 NTU. Objects not mentioned are supported as stated in the MIB.

System Group ± ªsysDescrº Object (system 1)

This object provides the full name and version identification for the system hardware and software. This object displays the following string for 2-port and 4-port

E1 NTUs (1-port E1 NTUs do not have H/W CCA2):

E1 HDSL NTU; model: xxxx-xx-xxx; S/W Release: yy.yy.yy; H/W CCA1: z z z z-zz z; H/W CCA2: zzzz-zzz; H/W CCA3: zzzz-zzz; Serial number: sssssss.

Where: xxxx-xx-xxxrepresents the full model number of the unit.

yy.yy.yyrepresents the software revision number of the unit.

z z z z-zz z represents the hardware revision numbers of the unit.

sssssssrepresents the serial number of the unit.

System Group ± ªsysObjectIDº Object (system 2)

This object provides the authoritative identification of the network management subsystem contained in the unit. This object displays the following object identifier:

33601.3.6.1.4.1.74.1.14.2.3.2

33641.3.6.1.4.1.74.1.14.2.3.3

33651.3.6.1.4.1.74.1.14.2.3.4

System Group ± ªsysServicesº Object (system 7)

This object provides a value which indicates the set of services that are potentially offered by the E1 NTU. Only the following values are supported by the E1 NTU.

•physical(1) ± Layer 1 functionality for all interfaces.

•datalink/subnetwork(2) ± Layer 2 functionality (SLIP, PPP) for the COM and AUX ports.

•internet(4) ± Layer 3 functionality (IP) for all management links.

•end-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 Interface 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 E1 NTU provides an entry in the interface table for the network interface, the G.703 DTE interface, each of the synchronous data ports (1, 2, or 4 depending on the model), the COM port, and the AUX port, if they apply. 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 E1 NTU.

Interface Group ± ªifNumberº Object (interfaces 1)

This variable contains the maximum number of MIB II supported interfaces possible across the 33xx 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 33xx Series models.
