FAIL

The board is reporting that it is running half duplex with auto-negotiate (y). 
Communication Manager is trying to negotiate the settings on the circuit 
pack to match the administered settings and, under the above condition, it 
is logging a fault. It could be argued that this is a false alarm, especially if 
the link is operating correctly with no observable degradation of service. 
Note: Do not immediately replace the board for this fault. There is a 

mismatch between what is programmed in the board and administration on 

Communication Manager. 

CAT-3 wiring does not support 100Mbps data rates. Wiring between the 

backplane and router must be CAT-5
Follow these steps to attempt to resolve the problem. 

1. Change the ethernet options. Set the speed to 100Mbps with full 

duplex. Set Auto (negotiate) to n. This should match the settings of the 
connected router. If the router does not have the same capabilities, you 
may have to adjust accordingly. The important thing is to make the 
media processor (TN2302) and the connected router match. 
Command steps to accomplish changes to Communication Manager 
administration. 

a) Enter get ethernet-options location to determine current 

settings, both administered and actual.
b) Enter change ip-interface location (Enable Ethernet Port 

field to n) to turn off the interface. Submit the command to disable the 
interface.
c) Enter change ip-interface location  change the Ethernet 

Options fields as required. Submit the form.
d) Enter change ip-interface location  (Enable Ethernet 

Port field to y) to turn on the interface. Submit the command. to enable 
the interface.
e) Enter get ethernet-options location to verify that Ethernet 

options are the same in administration and on the board.

1. If service is normal and the alarm is causing concern, disable the test 

and escalate the problem.
