SNMP MIB Objects

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.

Hforwarding(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.

IP Group – “ipRouteTable” Object (ip 21)

The routing table used by the DSU/CSU is supported as a read/write table. Entries in this table may be added, deleted, or changed. You should exercise great caution when adding or modifying routes in the ipRoutingTable. In general, it should not be necessary to add or modify routes in the DSU/CSU. In those cases where it is deemed necessary, the routes should only be added to the connected device (i.e., the device closest to the destination). Internal routing mechanisms will propagate the route to the other devices.

An existing route may be effectively deleted by setting the ipRouteType object to “invalid” for the entry to be deleted. An existing route may be modified by changing fields in the desired entry (indexed by ipRouteDest) of the routing table. A new route may be added by specifying values for a table entry for which the index (“ipRouteDest”) does not already exist.

To add a route using an SNMP set, you must specify a group of minimal objects. These variable bindings must be contained in a single Protocol Data Unit (PDU). The objects are described in more detail in the following sections. The minimal set consists of:
