Hello
there are many RTN in my network have this Alarm !! DCNSIZE_OVER .. I already asked local huawei team about it .. they said that no solution and network nms supervision is saturated !!
I found this in the net about it

Replan the DCN network based on actual networking conditions.

The DCNSIZE_OVER alarm occurs when the number of nodes (NEs, NMS servers, and NMS clients in a network segment) on an L2 DCN subnet is greater than 30. The solution is to divide the L2 DCN subnet.

The DCNSIZE_OVER alarm occurs when the number of nodes (NEs, NMS servers, and NMS clients in a network segment) on an HWECC subnet is greater than 150. The solution is to divide the HWECC subnet.


but I really don't know how to do !! should I have database of my link to change something ?

thanks for help

From I know,
1. You should replan the DCN: divide the DCN network based on the limition of L2 DCN and HWECC;
2. Selecting a gateway NE for Each Subnet;
3. Checking whether the new gateway NEs work normal;
4. Disconnecting the DCN between subnet
5. Verrifying the subnet division result

This can be done by disable the DCC channel for the interconnecting interfaces, there is a DCC management function in NE Explorer for it.
