hi there from Russia!
i'm setting up new LAN on iSCSI based on Aruba 3810M 16SFP+, G9/G10 DL380 servers with 560/562 FLR-SFP+ Adapters and MSA 2062.
Now i have 2 problems:
1. Can't ping with jumbo frames (9000 bytes). Success ping only up to 1500 bytes.
2. Low bandwidth ( iperf avg 4.5 Gbits/sec )
in conclusion:
- Jumbo frames enabled on all devices (nic, swithes).
- copper wires
- Windows server 2016
- lates drivers
Solved! Go to Solution.

SolutionHi! supposing you've two Microsoft Windows hosts connected through the very same 10G Switch (the Aruba 3810M 16SFP+ <- does a "show vlans" report Jumbo = Yes on relevant VLANs used for testing?) and all - end-to-end - is properly configured to manage MTU at 9000 bytes (Jumbo frames) then what's the output of:
ping -f -l 9000 <IP-of-Peer-A>
executed on Peer B and also the output of:
ping -f -l 9000 <IP-of-Peer-B>
executed on Peer A.
That's to see if Jumbo Frames pass.
