[Bug 1660324] Re: There is no way to specify which port use for which network

[Seamanhanshan]

Just as your case shows, if server is booted with only nic  --nic net-id
=uuid-of-net-1, the result is also random.

Title:
  There is no way to specify which port use for which network

Status in Ironic:

Bug description:
  Baremetal server has two ports. Each port leads to separate hardware
  switch (defined by local_link_connection/switch_info).

  When nova instance is booted with two nics, pointing to different
  networks, it randomly assign each (ironic) port to each networking.

  Baremetal server:

  NIC1 leads to switch sw-1 port 1/1/1
  NIC2 leads to switch sw-2 port 2/2/2

  switch sw-1 serves net-1
  switch sw-2 serves net-2

  server is booted with --nic net-id=uuid-of-net-1 --nic net-id=uuid-of-
  net-2

  Run1:

  NIC1 pointing to sw-1 port 1/1/1 and configured to serve net1
  NIC2 pointing to sw-2 port 2/2/2 and configured to serve net2

  Run2:

  NIC1 pointing to sw-2 port 2/2/2 and configured to serve net1
  NIC2 pointing to sw-1 port 1/1/1 and configured to serve net2

  This creates chaos if sw-1 is 'internet' switch and sw-2 is 'local DMZ
  switch'. sw-2 can not serve internet vlans, and sw-1 can not serve
  local network vlans.

  Ironic version: newton (6.2.1)
