OSN7500 Cannot Query Ecc Link On Packet Network

Problem Description: OSN7500 Cannot Query Ecc Link On Packet Network

[Problem Summary] Unable to query ECC LINK information in customer feedback packet network

[Problem Details] U2000: U2000 R6C00SPC300 OSN7500:R12C00 On the same network management, the NEs in the TDM network can query the ECC link, but the OSN7500 in the packet group cannot query the ecclink information.

Process

Try to view the ECC link management of the packet network element. There is really no ECC link. Then consider that this is a pure packet plane networking. The ECC link is established by D1-D3 in the SDH frame. The pure packet network has no SDH link. Why does the ECC link come from, and then find the IP-related entries in the menu of the NE management device, find the routing table of the communication between the network elements in the ip protocol stack management, and communicate with the tac. The network management also has a route lookup entry that merges the ECC link and the ip protocol stack, and the core routing table.

Root cause

The ECC link is established by D1-D3 in the SDH frame. The pure packet network does not have an SDH link, so there is no ECC link.
