Dear admin,

I found that S8016 Eth-trunk Link is Unreachable. I didn’t not know how to solve it. Then I through it Huawei support website & got my solution.

 

Huawei Feedback:

Two S8016s of one site are connected through Eth-trunk. One day Eth-trunk link is interrupted; S8016 fails to learn any ARP information from Eth-trunk.  S8016 fails to learn any ARP information from Eth-trunk interface. The forwarding of Eth-trunk module may prompt the fault.

Much information in the log is caused by ETAQ queue congestion. ETAQ queue is the distribution queue used by the eth-trunk. The eth-trunk sends the member list once to each interface board every five seconds. From the following scheduling queue, eth-trunk message queue is congested and cannot be released. As a result, ARP message cannot be processed. The interface board processes the task timeout, and ETAQ queue may be congested...

Thanks to Huawei team

very good & keep it up...
