Preventive Maintenance Procedure for ITI Supplied 3COM RAS
A. Physical Inspection before starting of the Preventive Maintenance
1. Check the Status of the LEDs on ARC cards (details of LED and expected
results is available in Annexure )
2. Check the Status of the LEDs on DSP cards (details of LED and expected
results is available in Annexure )
3. Check for the Status of the LEDs on NMC cards (details of LED and expected
results is available in Annexure )

options:
‘MONITOR RADIUS’
A) Monitor all RADIUS packets
B) Monitor all RADIUS authentication

C) Monitor all RADIUS accounting
packets
D) Monitor a specific user
E) Monitor next session
F) Monitor all packets to a specific
server

Test Result
Check for the authentication status of the next
session It gives details of the Access-Request
and Access—Accept or Access-Reject vis-àvis configured Radius.
Similarly, one specific user access-request,
access-accept/reject ( e.g. nib_test) may be
seen.

Use
command Select a letter for one of the following options:
C) Monitor PPP Call Events.
‘MONITOR PPP’
I) Monitor a specific interface.
N) Monitor the next session that starts
up.
U) Monitor a specific user.
T) Monitor a specific calling number.
X) Exit the monitor.
Please Enter Your Choice :
(i) Press ‘U’
To see the authentication details for the
specific users.
( e.g. One can see the session from one specific
user like ‘nib_test’ then enter this in the
user_name field and connect with ‘nib_test’
and see the result
(ii) Press ‘N’
Check for the Next session from any user that
starts up. that starts up
