In Netflow V9, the field length of the cflow.outputint and cflow.inputint is 4
byte. 

But the wireshark Filter size is limited to 2 bytes and get the following error
message . 

Please extend the Display filter size to 4 byte .

Example : while trying to do display filter = cflow.outputint == 151126156 get
the following message. 
======================================================================
"151126156" too big for this field, maximum 65535.

The following display filter isn't a valid display filter:
cflow.outputint == 151126156
See the help for a description of the display filter syntax.
