How to persist vlan settings (script help)?

[g1dtf]

I have an N66u (Rmerlin 374.43_2) with the following vlan settings.

robocfg vlan 20 ports "0t 8t"
vconfig add eth0 20
ifconfig vlan20 up
brctl addif br0 vlan20

I want them to survive a reboot and from what I have read this needs to be done with a script. I am looking for help in writing, installing and executing the script on my N66U . I have read various threads on this but finished up more confused than before.

Thanks

Andy.

There is a wealth of information here RMerlin Wiki and includes examples of implementing scripts on the router.

Basics for creating/exploiting scripts.

e.g. My_script.sh

1. Enable SSH access to router via the GUI

Administration->System TAB then Click 'Enable SSH=LAN only'
​

2. If you are using a Windows device then install WinSCP to create/edit the script file on the router.

I posted a mini-tutorial of getting a script onto the router via WinSCP:
Using WinSCP to create scripts/files on Asus Router​

or SSH into the router then use the router's nano editor.

3. As per the Wiki, ensure your script is executable

SSH to the router using your preferred SSH Client (Xshell6,MobaXterm or PuTTY etc.) and issue​

dos2unix   /jffs/scripts/My_script.sh
chmod a+rx /jffs/scripts/My_script.sh

4. Ensure that execution of scripts is enabled - either via the GUI

Adminstration->System TAB then Click 'Enable JFFS custom scripts and configs=YES'​

or from the command line

nvram set jffs2_scripts="1"
nvram commit

5. If you are logged on to the Routers SSH console you can now test the script

sh /jffs/scripts/My_script.sh

For your VLAN script, I suggest you use nat-start

/jffs/scripts/nat-start

#!/bin/sh

sleep 10     # Always for nat-start?

# Only create the VLAN if it doesn't already exist.
if [ -z "$(robocfg show | grep -oF "vlan20:")" ];then
   robocfg vlan 20 ports "0t 8t"
   vconfig add eth0 20
   ifconfig vlan20 up
   brctl addif br0 vlan20
fi

Thanks for the info but just for clarification regards nat-start. Is that a folder in which I place my script or the name of the script once created?

Read the Wiki …. e.g. User scripts

I have read that a couple of times and gathered that the scripts should be placed in /jffs/scripts/ and the script should be named nat-start etc but not sure whether the file needs the .sh suffix. Unless I am not understanding things correctly which is more than likely lol.
