Different mangement VLANID between cascaded RTN's causing not managed RTN

Publication Date:  2012-07-25 Views:  70 Downloads:  0
Issue Description
We use RTN980 V1R003C00 and using the inband DCN and between RTN's in the same site we make cascading using multimode fiber which also used for carrying 3G traffic.



Alarm Information
Null.
Handling Process
At the first check that the ports is enabled or not and make sure of the cascading connections between the RTN's and send start checking the DCN parameters and found that the management VLANID is different between the two RTN's so when we change the other VLANID and check with the NOC that they can see the other RTN and they can manage it.



Root Cause
The problem was that in the first RTN the management VLANID is different between the two RTN's.



Suggestions
While configuration the DCN must make sure of the configuration and confirm with the NOC that they can manage the device.
