On Extreme SLX Router, SNMP Management Information Base (MIB) uses Interface Index (ifIndex) to assign a unique identifying value to each interface.
The ifIndex is encoded per interface type and the assigned value is used if any information needs to be polled for a particular interface. The offline SNMP ifIndex generation tool which is developed based on Python, provides a means to find out the ifIndexes associated with various interfaces. This tool can run on any platform (SLX Router, Linux, or Windows) wherever the Python package is installed. The script is available on SLX Router at
/fabos/cliexec/ifindex_gen.py. If you want to run it on a Linux or Windows platform, you may have to modify the first line in the script to point to the location of the Python binary on the platform.
