scenario...

i have a host say controller-0

prior to any ansible run

[Greg] I assume you mean the bootstrap ansible playbook

i need to create a bond, and bridges and vlans

[Greg] You do need an interface to the outside world … e.g. in order to download container images from docker hub.

[Greg] Why can you not simply create a single interface (one link of bond) with a vlan ?

sure....

Add a bond device as root:

ip link add bond0 type bond

ip link set bond0 type bond miimon 100 mode 80211.ad ip link set enp33s0 down ip link set snp33s0 master bond0 ip link set enp44s0 down ip link set enp44s0 master bond0 ip link set bond0 up

Set VLAN on the bond device:

ip link add link bond0 name bond0.1648 type vlan id 1648 ip link set bond0.1648 up ip link add link bond0 name bond0.1664 type vlan id 1664 ip link set bond0.1664 up ip link add link bond0 name bond0.1680 type vlan id 1680 ip link set bond0.1680 up

Add the bridge device and attach VLAN to it:

ip link add br0 type bridge

ip link set bond0.1648 master br0

ip link set bond0.1664 master br0

ip link set bond0.1680 master br0

ip link set br0 up

so i see where in starlingx

[Greg] the following commands are only possible AFTER bootstrap

system host-if-add -c platform -a 802.3ad -x layer2 controller-0 bond0 ae enp33s0 enp49s0

system host-if-modify controller-0 $OAM_IF -c platform system interface-network-assign controller-0 $OAM_IF oam
system host-if-add controller-0 -V 1648 -c platform bond0.1648 vlan bond0
system host-if-add controller-0 -V 1664 -c platform bond0.1664 vlan bond0
system host-if-add controller-0 -V 1680 -c platform bond0.1680 vlan bond0

does allow for me to create the bond0 and the vlans? but I dont see any documentation for bridges anywhere ? Do I even need the bridge.
[Greg] No … there is no requirement for a bridge with StarlingX.

where i want to set example, since each needs its own interface can i set OAM_IF=bond0, and say MGMT_IF=bond0.1664

[Greg] Yes … i.e. OAM on port-based/untagged-vlan of bond and MGMT on vlan-tag=1664 on bond
( BUT here is where you need the pxeboot network because your MGMT network is vlan-tagged … and you can't pxe boot over that )

OAM_IF=bond0

MGMT_IF=bond0.1664

system host-if-modify controller-0 lo -c none IFNET_UUIDS=$(system interface-network-list controller-0 | awk '{if

($6=="lo") print $4;}')

for UUID in $IFNET_UUIDS; do

system interface-network-remove ${UUID}
done
system host-if-modify controller-0 $MGMT_IF -c platform [Greg] don't think you actually need this command
system interface-network-assign controller-0 $MGMT_IF mgmt
system interface-network-assign controller-0 $MGMT_IF cluster-host

the reason for this being our switches are

# MGMT

interface vlan1648

address 10.16.48.2/24

address-virtual 44:38:39:FF:00:02 10.16.48.1

vlan-id 1648

vlan-raw-device bridge

interface vlan1672

address 10.16.72.2/24

address-virtual 44:38:39:FF:00:03 10.16.72.1

vlan-id 1672

vlan-raw-device bridge

interface vlan1680

address 10.16.80.2/24

address-virtual 44:38:39:FF:00:03 10.16.80.1

vlan-id 1680

vlan-raw-device bridge

interface vlan1696

address 10.16.96.2/24

address-virtual 44:38:39:FF:00:03 10.16.96.1

vlan-id 1696

vlan-raw-device bridge

interface vlan1664

address 10.16.64.2/24

address-virtual 44:38:39:FF:00:07 10.16.64.1

vlan-id 1664

vlan-raw-device bridge

and further down DATAIF_0=bond0.1680

the reason being we are trying to have starlingx conform to our networks topology I also noted: in

https://docs.starlingx.io/deploy_install_guides/r6_release/ansible_bootstrap_configs.html#install-time-only-params-r6

...

Network Properties I listed at the bottom

can i modify these addresses to conform to our networks, as our switches wount pass the traffic you set as defaults, as seen in my first attempt at the bottom. Though i dont believe still dhcp/pxe will work on a vlan interface.
