E. SNMP MIB Objects

IP Group, MIB II

The IP Group objects are supported by the DSU/CSU for all data paths which currently are configured to carry IP data to or from the DSU/CSU, including the MODEM, COM, AUX, carrier SNMP bus, EDL, and FDL. All of the objects in the IP Group other than the IP Address Translation table are fully supported. The IP Address Translation table (ipNetToMediaTable) does not apply to the DSU/CSU and will be empty (i.e., have zero entries). The following sections provide clarification for objects contained in the IP Group when it is not clear how the object definition in MIB II is related to the DSU/CSU.

IP Group – “ipForwarding” Object (ip 1)

his object specifies whether the unit is acting as an IP gateway in respect to the forwarding of a datagram received by, but not addressed to, this unit. Only the Tfollowing value is supported by the DSU/CSU.

forwarding(1) – The unit is acting as a gateway.

IP Group – “ipAddrTable” Object (ip 20)

The address table is supported by the DSU/CSU.

IP Group – “ipAdEntAddr” Object (ipAddrEntry 1)

The ipAdEntAddr object is an IP address supported by the device and serves as the index to the address table. Since indexes for tables must be unique, only one ifIndex may be displayed for each IP address supported by the device. If you have configured the same IP address for multiple interfaces or for default IP addresses, you will not see all interfaces that support a particular IP address upon display of the ipAddrTable.

IP Group – “ipAdEntIfIndex” Object (ipAddrEntry 2)

For some address table entries, the ipAdEntIfIndex object may have a value greater than ifNumber. In these cases, the ipAdEntIfIndex refers to a proprietary interface which is not currently implemented by the interface group of MIB II.
