Extended ECC communication fails due to wrong mode setting
When different networks are communicating through router interconnections, the Extended ECC does not work when the mode of the Extended ECC is set to Auto mode. Setting it to the specified mode eliminates the failure.

Fault category
ECC Failure
Phenomenon Description
Two networks are connected via Ethernet cables and cannot communicate with the opposite network.
Cause Analysis
Possible causes are as follows:
The IP address is set incorrectly.
Extended ECC mode setting error.
Procedure
Query the IP addresses of the two network elements and the routers connected to them.
Network element A:
IP address: 129.9.1.1
Subnet mask: 255.255.255.0
Gateway: 129.9.1.111
Router A:
IP address: 129.9.1.111
Subnet Mask: 255.255.255.0
Router B: IP address:
129.9.0.111
Subnet mask: 255.255.255.0
Network Element B:
IP address: 129.9.0.1
Subnet mask: 255.255.255.0
Gateway: 129.9.0.111
The IP address is set correctly, but the extended ECC is still not working.
Check the setting of " ECC Extension Mode" to "Auto Mode".
Reset " ECC Extension Mode" to "Specified Mode".
Description:
Select network element A as the server and network element B as the client. Enter the IP address and port of Network Element A and Network Element B in "Server Settings" and "Client Settings" respectively.
After these operations, the extended ECC resumes communication.
Reference information
Auto Mode: Establishes the extended ECC connection automatically. This mode is convenient, but it establishes additional connections, which is not a good resource utilization, and is recommended only when there are fewer than 9 network elements. Both network elements establishing extended ECC must be set to auto mode for extended ECC to be established automatically.
Specified Mode: Establish extended ECC by specifying the server and client, with high connection reliability and high bandwidth utilization, this mode is generally used to establish extended ECC connections.
