Handling Process
We have Check both DSALAM control card have same MAC Address that’s way NE is not add at NMS.
Only adding device issue face at NMS. No outage and services are down reported.

Same mac Address at both side 00-25-9e-75-25-ab

we have perform tha Activity at Myzafer Gar DSALAM because at Muzafer Gar Dslam Current and defult Mac Address are changed.
we have changed theCurrent Mac Address with Defult Mac Address.as per below commands.
On site operation, first disconnect the connection with uplink equipment (pull out FE cable or GE cables) ; then pull out the standby board if standby board are there.
go to diagnose mode, and perform the command“display sysman mac-address”and check “Current MAC”
MA5600(diagnose)%%display sysman mac-address                          
Current MAC address of active mainboard: 
00-25-9e-75-25-ab                       
Default MAC address of active mainboard: 
00-25-9e-75-2c-3e
and found the current address are same as other device MAC address, that is why it is conflict.  So need to modify the current MAC address same as default MAC address.
 The steps are as below:
MA5600(diagnose)%%sysman mac-address current
{ mac-value<P><XXXX-XXXX-XXXX> }:
00-25-9e-75-2c-3e
  Command:
          sysman mac-address current 
=00-25-9e-75-2c-3e
  Are you sure to modify MAC address?(y/n) [n]:y
>>password:            <---note that here input the password
sysman
  Command is being executed, please wait...
MA5600(diagnose)%%display sysman mac-address
  Current MAC address of active mainboard: 
00-25-9e-75-2c-3e
  Default MAC address of active mainboard: 00-25-9e-75-2c-3e
Then insert the standby board, let standby board sync the same current MAC address with active boards.
Reconnect the device with upper device and check whether sysman mac-address/ arp ( by command: display sysman mac-address and display arp).
Now Add the device at NMS U2000.

Root Cause
we have check their NMS services and HSI services both are normal and there is no conflict of MAC at BRAS end
NMS VLAN interface are UP of Both side. But the MAc address are same.



Suggestions
please Check Auto save funtion enable At dslam.
Please Reboot the System After Activity.
