• -r specifies that you want to probe a specific remote node identified
by remote_node_name . The probe is done on all operational routes to
the remote node.
• -T specifies that you want to set the tracing level for the HyperFabric
software and the firmware to trace_level , which can be one or more
of the following (you can specify either the keyword or the
hexadecimal value):
reset or 0x0 Reset tracing to the default level
for all components (that is, turn
off all tracing).
send_path or 0x0002 Trace the HyperFabric software
send path.
packet_data or 0x0004 Trace the packet data.
packet_hdr or 0x0008 Trace the protocol headers
(TCP/UDP/IP).
data_struct or 0x0010 Trace the HyperFabric software
CLIC-specific data structures and
events.
rcv_path or 0x0020 Trace the HyperFabric software
receive path.
control or 0x0040 Trace the HyperFabric software
control messages.
all or 0xffff Turn on all possible trace levels.
Note that this will have a severe
impact on performance.
To find out what the current tracing level is, run this parameter (-T)
without any keyword or hexadecimal value specified.
• -D specifies that you want to dump the trace buffers from the kernel
to a user-space file and format the data using the formatter TCP_IP.
The HyperFabric software trace data is dumped into the file
/var/adm/clic_ip_drv.trc and formatted.
• -C TCP_IP operates in a way similar to -D TCP_IP, except that the
trace data in the kernel is dumped at regular intervals to the trace
file /var/adm/clic_ip_drv.trc0, and if that file gets full, to
/var/adm/clic_ip_drv.trc1. So, new trace events are appended to
the trace output file. This stops when tracing is turned off.
