Applies to

  • HCI 1.6 NDE deployment.
  • Bond10G is set to DHCP

Issue

When running NDE deployment with the Bond10G interfaces set to DHCP, NDE fails during the initial phases. From the nde.info log file we can find errors related to jumbo frames tests:
  
"failed to respond to a jumbo frame ICMP request"
"failed jumbo frames validation with value of [1500]"

These lines indicate that jumbo frames (MTU 9000) might not be enabled or working properly on Bond10G between the nodes.
However, when looking at the storage and compute node TUI, we can see MTU is set to 9000.
