I'm Trying to capture Infiniband packets using the pcap format, and for that i thought i should use LINKTYPE_INFINIBAND 247 DLT_INFINIBAND as mentioned in the tcpdump's LINK-LAYER HEADER TYPES.
When i try to open the pcap file in Wireshark i get this error message -
The file "ib.pcap" is a capture for a network type that Wireshark doesn't support. (pcap: network type 247 unknown or unsupported)
Moreover, in wireshark sample captures - InfiniBand the sample is -
File infiniband.pcap (8.7KB)
Description A libpcap trace file of low level InfiniBand frames in DLT_ERF format.
So, why DLT_INFINIBAND (247) is not recognized by wireshark, and why the sample uses DLT_ERF (197)?
Thanks!
