[6.8.3] How to make "setageing" bridge variable persistent

UPDATE - For now, I have put "brctl setageing br1 0" in the Unraid Go file, which is a way to make the setting persistent across boots although I'm sure there's a better way.

 

One of the bridges in my server requires that the setageing parameter is set to "0".  This relates to a workaround I'm trying to create for issues with capturing/processing network traffic inside VMs (using promiscuous mode).  I'll be updating a number of posts I have to help people with this once I've solved the persistence part of this issue.

 

I can successfully set the parameter by manually running (br1 being the bridge I need this applied to):

 

  brctl setageing br1 0

 

...but this is not persistent across boots so I've gone looking for where the default setting is coming from on boot. 

 

The default setting is at least referenced in:

 

  /sys/devices/virtual/net/br1/bridge/ageing_time

 

....however this setting gets overwritten on boot

 

It appears as though the following config file would need to be edited:

 

  /boot/config/network.cfg

 

....but I've tried adding what I interpreted the correct config option should be but I may have used the incorrect syntax.  I added the following line:

 

  BRAGEING[1]="0"

 

I came up with that line based on looking at what someone else had done in Proxmox.  They used:

 

/etc/network/interfaces
<snip>
auto vmbr1
iface vmbr1 inet manual
bridge_ports eth1
bridge_ageing 0
bridge_stp off
bridge_fd 0

 

....whereas the syntax in Unraid looks like this and as I mentioned is located in  /boot/config/network.cfg as opposed to /etc/network/interfaces:

 

IFNAME[1]="br1"
BRNAME[1]="br1"
BRNICS[1]="eth1"
BRSTP[1]="no"
BRFD[1]="0"

Can anyone help to identify where this setting should reside?  Would much appreciate.  This seems to be the best workaround to the feature request I posted at:
