I think the ifindex is changing, but why? They claim to be very "IOS-like". This behavior can very easily break network monitoring systems, as the interface indexes they request can be dynamically assigned to different interfaces during a reboot. IFindex can change when new interfaces come on line new interface include sub interface and loopback in order to keep persistent values for assigned interfaces we can use the command snmp=server ifindex persist A command applied to an interface is automatically applied to all the subinterfaces associated with that interface.
