In case of LOS alarm, continue investigation using the Physical Link failure
procedure.
Minimal number of active links
³
To check the number of minimal active links in the IMA group:
1.
Go to Configuration>Applications>ATM>IMA.
3. Min RX/TX links[1 - 16]
... (1)
2.
Check the actual number of active links.
3.
Go to Monitoring>Applications>ATM>IMA>Group status.
Active TX links
... (1)
Active RX links
... (1)
In case of a lower number, try to reduce the Min Rx/Tx links under the IMA
configuration to a lower value in order to allow the operating links to restore the
IMA group.
Differential delay
³
To check the current observed maximum differential delay between the IMA links:
1.
Go to Monitoring>Applications>ATM>IMA>Group status.
... (N)
Max observed differential delay ... (0)
2.
Check the value does not exceeds the maximum differential delay allowed.
3.
Go to Configuration>Applications>ATM>IMA.
6. Max differential delay (ms)[1 - 100] ... (25)
If the observed value is higher than the permitted one, increase the allowed
maximum differential delay.
Clocking issues
³
To check the clocking configuration on the IMA group:
•
Go to Configuration>Applications>ATM>IMA.
9. Common TX clock source > (System)
If set to system, check the status of the current clock as follows:
1.
Go to Monitoring>System>Clock>Current clock.
