Connect the cable between the DTS card (Monitor port) to any of
the icc port at the IOP (i.e. icc5)
Care must be taken that the action field entry of the selected icc
port in /etc/inittab file should be marked "OFF".

Invoke PORTMON Utility by giving the following command at
IOP prompt
IOP5C> Portmon –c
System shall ask for the port number thus enter 5
System asks for the input file name thus give the full path
/tmp/cmd
System asks for file name where slip values are desired to be
dumped give
/tmp/slip.log
Now System asks for the baud rate enter 4800
System asks again for Port No. enter – 1
The utility shall start dumping slip values in slip.log file
Each line starting from N represent a frame slip hence we can
calculate from these values, the number of frame slips occurred
every 10 minutes as the time stamp is printed every 10 minutes.
SLIP Utility
This utility will convert the Slip values in hex stored via PORTMON
utility to a more user friendly format in decimal.
It may be noted that this utility is an inherent part of UNIX releases
after 11.2 and higher.
At IOP prompt, please give one of the following options:
(i)
Slip –c –m X <slip.log
(ii)
Slip –c –h Y <slip.log
Where 'X' is the time interval in minutes for which slips are to be
calculated by the utility (The value of X shall be either 10 or a multiple
of 10)
Where 'Y' is time interval in hours for which slip has to be calculated.
Where 'slip.log' is the file available after running PORTMON Utility.
