workflow variations

pseudocode of test scenarios

add subports before boot, all at once

for 1 parent port:
    network create
    subnet create
    port create

for N subports:
    network create
    subnet create
    port create

trunk create with N subports
server create with parent port

N = 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

add subports after boot, one by one

for 1 parent port:
    network create
    subnet create
    port create

trunk create with 0 subports
server create with parent port

for N subports:
    network create
    subnet create
    port create
    trunk set (add one subport)

port list
port list --device-id server-uuid
server show

N = 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

add subports after boot, in batches

for 1 parent port:
    network create
    subnet create
    port create

trunk create with 0 subports
server create with parent port

for N batches of subports:
    for M subports in a batch:
        network create
        subnet create
        port create
    trunk set (add M subports)

port list --device-id server-uuid
