fcPing

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
have 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
3*100 = 300 frames 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.
