linux bridge - howto: bridge-stp on

[hk@]

Hi
is there any way to get "bridge-stp on" set using the proxmox-networking-config?

it seems default is off and I found no way to change this.

thx

Hi,

no, you must edit it directly in the file /etc/network/interfaces
But why do you need spanning-tree on a bridge where you have normally just one port?

 

[hk@]

well redundancy on relatively cheap switches:
one LACP bond is the primary uplink for a bridge connecting the VEs/VMs to their network.
another bond is the secondary uplink provided via a different switch in order to prevent a loop we obviously need STP.
and this works well - only a RSTP "on" switch at the webgui-level would be nice

For RSTP you have to install mstpd.
Ther is no implementation on the Linux bridge for this.
But mstpd works fine.

well, I mis-wrote, a simple STP on switch would be fine
(though RSTP support in proxmox would be fine too)

You can enable STP on the bridge or install and configure mstpd.
A GUI integration is not planted because this is an edge case and not a common PVE setup.
