Ping "DUP!" packets during backup

Veeam Logoby m.novelli » Tue Jun 07, 2016 1:08 pm

Hi guys, have you ever seen "DUP! ping packets" to VMware hosts during Veeam Backups?

Everything seems to works fine despite the warning of DUP! pings

The customer environment:

Dell PowerEdge R430 nodes with Broadcom QLogic 57810 10 GbE network adapters
VMware ESXi 6.0 U2
Veeam 9.0 Update 1, NBD mode
Dell Networking X1052 switch

All bios/firmware updated

The "DUP!" ping packets are generated pinging the VMware hosts, pinging the VMs doesn't show this issue

Thanks for any info,

Hello, We are having a similar issue and we think is related to the QLogic 57810 Card or Driver. We only see the issue when the cards are under heavy load (i.e. during the backups). It would be nice to know if you finally found a solution for it.
