Step 1 Capture data packets between:
-
IPC<->BBU
-
BBU<->Core network
-
Core network<->IVS
Step 2 ***yze the captured data packets. The analysis shows that the
core network filters IP segments with small data length. However, the
core network does not take IP layer parts into consideration. The core
network discards data packets with a small number of bytes.
Step 3 Change the MTU value or restore the MTU value to the default (1500).
Access the web page of the IPC, choose Settings > Network Configuration > MTU Parameters, and change the MTU value.
Step 4 Upgrade the eCNS600 core network device to the latest version.
Step 5 Check whether the fault is rectified.
-
If yes, no further operation is required.
-
If no, contact your service provider for assistance.
