SmartMIB Small Solution:

IP Datagram Error Statistics (Detecting Routing Loops)

(SM-SmallSol0033)

Solution Overview:
 

This management solution focuses on detecting ONLY those devices that are designated as network Gateways and are indeed an IP Datagram forwarding devices.

The solution defines a module name and description, then initiates the polling process under which the Devices (or in a specified AMZ) are fed into the polling SNMP engine, where the Gateway status of the device is determined through polling the value of the ipForwarding MIB Object. A variable handler is then defined to store the value which is then tested with an IF conditional statement; if the status for the particular device is ‘Forwarding’ then the counters for the IP Datagram Errors are collected. The particular errors reported in this management process are:

• The number of IP Datagram discarded because no route could be found to transmit them to their destination.

• The number of IP Datagram discarded due to lack of buffer resources.

• The number of input Datagram discarded because the IP address in their IP header's destination field was not a valid address to be received.

• The number of input Datagram discarded due to errors in their IP headers particularly Time-To-Live counter expiration.

The number of locally-addressed IP Datagram received successfully but discarded because of an unknown or unsupported protocol.
