The ERNIC IP has a number of status registers implemented to allow for extensive debug in case of a failure. These registers along with counter information from the initiator RNIC, for example Mellanox, can provide vital clues to debug any failure. The debug tools available to the system debugger working with ERNIC IP are:
• ERNIC complete register dump
• Promiscuous or packet sniffer mode counters (from the initiator RNIC),
• HW counters (from the initiator RNIC).
The steps to dump the different logs are explained in the following sections.
