Paradyne 3160-A2-GB21-50 manual IP Group ± ªipAdEntAddrº Object ipAddrEntry, IP Group, MIB

ACCULINK 316x DSU/CSU

Interface Group ± Output Counters (objects ifEntry 16 to ifEntry 21)

These objects collect statistics on the data received by the COM port, the AUX port, and the MODEM port when these ports are configured as SNMP management links. For interfaces that are not configured as an SNMP management link, these statistics are not provided and an error status is returned if access is attempted. The objects used to collect output statistics are listed below:

•ifOutOctets (ifEntry 16)

•ifOutUcastPkts (ifEntry 17)

•ifOutNUcastPkts (ifEntry 18)

•ifOutDiscards (ifEntry 19)

•ifOutErrors (ifEntry 20)

•ifOutQLen (ifEntry 21)

IP Group ± ªipAdEntAddrº 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 ± ªipAdEntIfIndexº 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, 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 ± ªipForwardingº 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 ± ªipAddrTableº Object (ip 20)

The address table is supported by the DSU/CSU.

IP Group ± ªipRouteTableº 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 ªinvalidº 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 (ªipRouteDestº) 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:

•ipRouteDest

•ipRouteIfIndex
