F. SNMP MIB Objects
F-10
March 2001 3160-A2-GB24-10
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)
This 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
following 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.
