New Command in v3.1.2
Basic Statistics
Basic statistical report variables give an indication of ISL congestion along the
path. They include the following:
Extended Statistics
Extended statistics report variables of general interest. They include the following:
Reverse Path
In general, the path from port A on switch X to port B on switch Y might be
different from the path from port B to port A. The difference could be in the links
traversed between the same sequence of switches, or the reverse path might even
involve different switches. The trace reverse path option allows the user to
determine both routing and statistical information for the reverse path, in addition
to those for the direct path.
Source Route
The source route option allows the user to specify a sequence of switches or ports
(or areas) that the pathInfo frame must follow to reach the destination.
Therefore, the path might be different from the one the actual traffic will take from
source to destination.
14
B/x
Bytes per second.
Txcrdz
The time in milliseconds that the port has been prevented from
transmitting frames due to lack of buffer-to-buffer credit. This
is an indication of downstream congestion. Note that other
commands (portShow, for example) may express this value
in units other than milliseconds.
F/x
Frames per second.
Words
Total number of four-byte Fibre Channel words.
Frames
Total number of frames.
Errors
Total number of errors that might cause a frame to be received
incorrectly. This includes CRC errors, bad-EOF errors,
frame-truncated errors, frame-too-short errors, and encoding
errors inside a frame.
