fcPing
2
--quiet
Suppresses the diagnostic output. Only zoning information, if applicable, and the
summary line are displayed.
The following operands are valid only when fcPing is executed to perform a SuperPing:
--allpaths [ args ] destination
Executes a SuperPing that covers all available paths to the specified destination.
The number of actual paths covered depends on two other parameters that you
can optionally specify. When you issue
fcping --allpaths for a destination without
any other options, SuperPing covers all ISLs in the routes between source to
destination but does exercise all possible combinations of end-to-end paths. This
operand is required when executing
fcPing as SuperPing.
The following operands are optional and valid only with the --allpaths option:
-printisl
Displays statistical data for each ISL and internal port along the paths traversed
by SuperPing. This information displays in addition to the path display.
-covcount N
Specifies the minimum number of times each ISL is exercised by the SuperPing
command. The command sends
N frames and checks if each ISL is exercised at
least N times. When the condition is met, superPing exits and prints the statistics.
The default value is 5.
- maxtries M
Specifies the maximum number of frames to be sent before SuperPing exits. If
both
-maxtries and -covcount are specified, SuperPing checks the ISL coverage
and keeps resending framers until the minimum coverage condition to is met or
until the maximum number of echo frames specified in
maxtries has been sent.
For example, assuming a coverage count of 100 and a Maxtries value of 300,
SuperPing will send 100 frames at a time and checks if each ISL is covered at
least 100 times. If not, SuperPing will keep sending 100 frames at a time to check
for coverage up to 3 times for a maximum of 300 frames (3*100 = 300) on each
egress port. If this value is set too low in relation to the specified coverage count,
not all ISLs may be covered. The default value is 100.
-delay D
Includes a delay of D milliseconds between each echo frame sent.
-framelength len
Specifies the size of the data to send.
--help
Displays the command usage.
