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.”
This command was integrated into the 12.1 T release train.
Interface Index Persistence means that ifIndex values in the IF-MIB persist across reboots, allowing for consistent indentification of specific interfaces using SNMP.
The snmp ifindex persistenceinterface configuration command enables and disables ifIndex persistence for individual entries (corresponding to individual interfaces) in the ifIndex table of the IF-MIB.
The snmp-server ifindex persistenceglobal configuration command enables and disables ifIndex persistence for all interfaces on the routing device (this applies only to interfaces that have ifDescr and ifIndex entries in the ifIndex table of the IF-MIB).
IfIndex commands configured for an interface apply to all subinterfaces on that interface."
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
