ixClearTimeStamp
ixClearTimeStamp - synchronizes the timestamp value among all chassis
SYNOPSIS
ixClearTimeStamp portList
DESCRIPTION
The ixClearTimeStamp command sends a message to the IxServer to synchronize the timestamp on a group of chassis. This feature is useful for calculating latency on ports across chassis.
ARGUMENTS
portList
(By reference) The list of ports in one of the following formats:
one2oneArray, one2manyArray, many2oneArray, many2manyArray
Or a reference to a list. For example, pl after
set pl {{1 1 1} {1 1 2} {1 1 3} {1 1 4}} -or-
set pl {1,1,1 1,1,2 1,1,3 1,1,4}
RETURNS
0
No error; the command was successfully delivered to the IxServer.
1
Error; the command was delivered to the IxServer but it could not process the message.
