Packets drop when perform V-motion to failover

There is a problem when we perform V-motion to failover server between ESX server, we found the Guest Server could not get online until we disable/enable the VM server network, or wait until it up (around 10 ping time out)

Using the mac-address update arp command, it can enable the S6700 to update outbound interfaces in ARP entries when outbound interfaces in MAC address entries change.

Solution:

Add "mac-address update arp" to these switchs.
<HUAWEI> system-view
[HUAWEI] mac-address update arp

 

Using the mac-address update arp command, you can enable the S6700 to update outbound interfaces in ARP entries when outbound interfaces in MAC address entries change.
Using the undo mac-address update arp command, you can disable this function.
By default, the S6700 does not update outbound interfaces in ARP entries when outbound interfaces in MAC address entries change.
