Common questions about extended ECC on WDM NEs

1

Question:
How many NEs can be interconnected using automatically extended ECC at a site?
Analysis:
At many sites, all NEs are interconnected using automatically extended ECC. As a result, there is a large number of NEs using this function for interconnection, and NEs are frequently unreachable by the NMS.
Answer:
1. If an Ethernet is used to establish an extended ECC channel for communication, at most four extended ECC channels are required. With manually extended ECC, a server can be connected to at most 7 clients, and each client can be further connected as a server. Hubs (or switches) can be cascaded, which is related to the network scale limit only. The basic principle applies to each product and is related to the platform.
2. The method of cascading metro WDM devices using ETHERNET1 and ETHERNET2 ports does not apply to a long-haul WDM system. For long-haul WDM devices, the ETHERNET2 port is not used for ECC communication. In addition, you are advised to cascade at most eight network ports in a metro WDM system.

Differences between manually extended ECC and automatically extended ECC
1. In terms of functionality, there is no difference between manually extended ECC and automatically extended ECC. Automatically extended ECC is used by default. 2. Manually extended ECC is recommended when there are more than four NEs.

Methods used to enable the extended ECC on the SCE board of a WDM device
1. Configure a client NE A. In the status diagram of an optical NE, right-click a client NE and choose NE Explorer. B. Choose Communication > ECC Management from the navigation tree on the left. C. Click Refresh and check the current ECC mode of the NE. D. Set ECC Extended Mode to Specified Mode in the function panel on the right. E. In the Set Client area, enter the IP address and port number of the server NE in the Opposite IP and Port fields respectively. F. Click Apply. The Operation Result dialog box is displayed, indicating that the operation is successful. G. Click Close. 2. Configure a server NE. A. Log in to the NMS. B. Double-click an optical NE. The status diagram of an optical NE is displayed. C. Right-click a subrack NE and choose NE Explorer from the shortcut menu. D. Choose Communication > ECC Management from the navigation tree on the left. E. Click Refresh and check the current ECC mode of the NE. F. Set ECC Extended Mode to Specified Mode in the function panel on the right. G. In the Set Server area, enter the port number in the Port field. The port number must be consistent with that of the Port field set for the client NE. H. Click Apply. The Operation Result dialog box is displayed, indicating that the operation is successful. I. Click Close.
