No - that's normal.
You've told the library to load the CISCO-PROCESS-MIB via the -m flag,
then you've told the library to load it again by including it in the name
of the object itself.

I suspect that
    snmpget -c public -Dparse-mibs -m CISCO-PROCESS-MIB -v 1
                     129.127.71.2    :cpmCPUTotal5min.9
and
    snmpget -c public -Dparse-mibs    -v 1 129.127.71.2
                    CISCO-PROCESS-MIB::cpmCPUTotal5min.9

would both give basically the same output as the numeric form,
except for the final error:


> < CISCO-PROCESS-MIB::cpmCPUTotal5min.9: Unknown Object Identifier
>     (Index out of range: 9 (cpmCPUTotalIndex))

I really don't understand that last message.
The definition of cpmCPUTotalIndex gives a range of 1..4294967295
so 9 is perfectly valid.

As a workaround, try
     snmpget -Ir  -c public -v 1 129.127.71.2
                    CISCO-PROCESS-MIB::cpmCPUTotal5min.9

(That's "minus-capital-i-lower-case-r")

Does that work?
