kdump over ssh with LACP bond won't work

Solution Verified - Updated -

Issue

  • kdump over ssh with LACP bond won't work
  • Capturing a vmcore to a network dump target fails because the LACP bond takes some time to negotiate
  • Connecting to the SSH vmcore server fails with no route to host as both the bond slaves are in DOWN state

Environment

  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 9
  • kdump/kexec to capture vmcore
  • Remote network dump target (eg: SSH)
  • NetworkManager
  • bonding with LACP
