T4-4 ldm guest Create link aggregation aggr1 with optical fibre and share network Packet loss

HI,Okami and everyone

   We have a set of supercluster which has two t4-4 in my production environment.That is not a new project.

In short it each T4-4 have ldm primary control two ldm guest.The two ldm guest installation zones and configuration cluster.

That ldm guest create link aggregation aggr1 with optical fibre in this case. Final start more than 4 cluster zones

 or start more than 4 sigle zones will may all the zones and ldm share network Packet loss.

 We cooperate with network engineers to test many methods still Packet loss.How to deal with?

in H3C Switch ping 4 Different zones and ldm ip address still Packet loss
