Hi All !

In erf.h at the list of ERF headers, there is:

#define ERF_TYPE_IP_COUNTER         13

Does anyone know what it is? What is it for?

Yes, Endace, the creator of the ERF file format and thus of the ERF header, does. Unfortunately, they haven't done a very good job of keeping their description of that file format online (it's labeled as "Confidential" in the page footer, the fact that they contribute GPLed code to handle a lot of it nonwithstanding).

The description in their document isn't entirely clear, but it looks as if an ERF_TYPE_IP_COUNTER record has a list of IPv4 addresses and 32-bit counts of packets seen with that address as a source address and with that address as a destination address.
