Interfaces left over after playing with LAGGs

NogBadTheBad

I was having a play trying to set up my single switch link to a LAGG, Created the new LAGG and tried to move VLAN 9
to the LAGG, it didn't work, so i deleted them.

If I do an ifconfig I still see the following:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
description: OPT1

lagg0.9 & lagg0.9.9 also appear as parent interfaces in the Lagg - > Edit page and Available Network Ports on the Interface -> Assignment page.

What's the best way to remove them, i did a roll back pre change.

Mmm, that's interesting. lagg0.9.9 is a QinQ interface, did you mean to create that?

If they don't exist in the config you can just remove them at the command line with ifconfig. You would need to start with lagg0.9.9 and then it's parent lagg0.9 etc.
Or just reboot.

Enabled OPT1.

Created LAGG0 and added OPT1.

Tried to move vlan 9 off its current interface LAN / igb0 to LAGG0, it failed.

Tried again and it still failed, I think thats when lagg0.9.9 was created.

I was trying to move the VLANS over to the LAGG and then add LAN to LAGG0.

@stephenw10 A reboot seems to have sorted it.

Ah:-

"Do not edit the existing tags and change the parent interface, it will cause problems with the interface assignments. Always create new tags, switch the assignments, then remove the old tags."
