Paradyne 317x E1 manual IP Group, MIB

Interface Group ± ªifLastChangeº Object (ifEntry 9)

This object contains the value of ªsysUpTimeº at the time the interface entered its current operational state. For the E1 DSU/CSU, this object is only updated for the ªupº and ªdownº states. This is done since the ªtestingº state is not mutually exclusive with the ªupº and ªdownº states.

Interface Group ± Input Counters (objects ifEntry 10 to ifEntry 15)

These objects collect statistics on the data received by the COM port and the AUX 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 input statistics are listed below:

•ifInOctets (ifEntry 10)

•ifInUcastPkts (ifEntry 11)

•ifInNUcastPkts (ifEntry 12)

•ifInDiscards (ifEntry 13)

•ifInErrors (ifEntry 14)

•ifInUnknownProtos (ifEntry 15)

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

These objects collect statistics on the data received by the COM port and the AUX 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, MIB II

The IP Group objects are supported by the E1 DSU/CSU for all data paths which currently are configured to carry IP data to or from the E1 DSU/CSU, including the COM, AUX, 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 E1 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 E1 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 E1 DSU/CSU.

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

IP Group ± ªipAddrTableº Object (ip 20)

The address table is supported by the E1 DSU/CSU.

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.
