The "snmp ifindex persistence" interface configuration command enables and disables ifIndex persistence for individual entries (corresponding to individual interfaces) in the ifIndex table of the IF-MIB.

-- So the above command is on a per interface basis


The "snmp-server ifindex persistence" global 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).

The former is the one you should be using as it is supported on most IOS versions. The latter is equivalent where it is supported.
