System Group, MIB II

The System Group objects are fully supported by the

E1 DSU/CSU. 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 DSU/CSU. 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:

E1 DSU/CSU; model xxxx-xx-xxx; S/W Release: yy.yy.yy; H/W CCA1: z z z z-z zz; H/W CCA2: z z z z-zz z; 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:

31721.3.6.1.4.1.74.1.14.2.2.5

31741.3.6.1.4.1.74.1.14.2.2.6

System Group ± ªsysServicesº Object (system 7)

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

•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 DSU/CSU provides an entry in the interface table for the network interface, the DTE Drop/Insert interface, each of the synchronous data ports, 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 DSU/CSU.

Interface Group ± ªifNumberº 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.
