NE80E Fails to Communicate with the ME60 Through the Eth-Trunk

Publication Date:  2013-09-03 Views:  32 Downloads:  0
Issue Description
The NE80E is connected to an ME60 through an OSN6800. After the negotiation auto command is executed on the GE interface on the NE80E, the NE80E can communicate with the ME60 through a single link. After the NE80E connects to the ME60 through the Eth-Trunk for dual-link protection, the NE80E cannot communicate with the ME60.
Handling Process
1. The NE80E can communicate with the ME60 through a single link. Therefore, the transmission configuration is correct.
2. Check the data configurations on the NE80E and ME60. The configuration of the negotiation auto command is lost on the GE interface of the NE80E.
Root Cause
The configuration of the negotiation auto command is lost on the GE interface of the NE80E.
Solution
After adding the GE interface on the NE80E to the Eth-Trunk, run the negotiation auto command on the GE interface to ensure the same negotiation mode on the two ends.
Suggestions

When the negotiation auto command is executed on the NE80E in a scenario where a single link is used, and the interface is added to an Eth-Trunk, the configuration of the negotiation auto command is lost. Therefore, run the negotiation auto command after the interface is added to an Eth-Trunk.
