For NMS applications we are using “using port index” to monitor interface/bandwidth of Cisco equipments. But the drawback of using this feature is this feature tendency to change after equipment reboot. Post which for NMS enabling we have to change PORT INDEX manually.
To avoid such condition, we have a get solution “snmp-server ifindex persist” command on cisco devices. (To be configure under USERmode or Interface Mode ..? please sugegst)
As we are not much familiar with the effectiveness of this command. We want to understand the working ,function and requirement of this command or feature…or can simply say looking for “How this command will solve our purpose of changing PORT INDEX number after device reboot.”
