If there is transmission device between two ends of the fiber, one is up and the other is down. For link bundling, if some link has such a problem, some address may not be pinged. Shutdown the up end and communication is normal.

Please refer to “Eth-trunk problem”.
The balance is based on traffic. Link bundling is based on MAC/destination MAC, source IP/destination IP for the forwarding of L2 and L3 and uses HASH.
VRP5.X has balance based on packet, and then there is no such problem. Only one packet is lost. Combine BFD with other technology to avoid the problem. Now all versions do not support the technology.
