Save setting to nvram

[doubleroll]

How can I save a particular setting to nvram so after a reboot I do not have to make the same changes?

example: ROBOCFG PORT 0 JUMBO ON

Not a big deal but it would be nice not to have to do this every time. Thx!

it would be easier to simply add that line to /jffs/scripts/services-start

or your original idea
saving a value would mean
saving 0 & ON , those are the values
robocfg is the program
port and jumbo are specific cmd's used to set the values above

you would need a script that knows what to do with those values

so yeah, much easier to add to services-start

I don't see the point in enabling Jumbo Frames on only one port of your switch. That means that any traffic forwarded from port 0 to any of the other ports will run into issues.

For jumbo frames to work properly, everything on the LAN segment must share the same settings.

Is there a way to adjust the mtu of the switch ports and save to nvram or is adding a call to ifconfig in a jffs script the only way?

Sorry yes that is what I would want to do enable on all ports on the LAN for jumbo. I would like it to be persistent so that a reboot will not require the commands to be manually run. Thanks!

I will give that a try Thanks!

LAN -> Switch Control

Set Jumbo Frames to "Yes" simply

Oops..I neglected to list an important piece of info, I am running in AP mode and do not have that option.

I also see that /jffs is read only and does not have a scripts sub-directory...I guess I can "chmod" it but don't want to break anything.

Thanks!

Not sure if the code will still initialize this properly while in AP mode (I didn't check), but give it a shot:

nvram set jumbo_frame_enable=1
nvram commit
reboot

Otherwise, see the Wiki on how to enable the JFFS partition, and then using user scripts.

the cmd you list above, would only change jumbo setting for 1 port not all ports

and if you want it on all ports
isn't there a check box in the gui for doing that

and I also agree with RMerlin
Jumbo frames are more trouble than it's worth
and it will probably negatively effect performance

edit: this is what happens when I respond from work
4 post happen, while I've started a response and working on something else
LOL

Thanks for all tour help I will give it a shot.

The nvram commands worked like a charm All LAN ports have jumbo frames enabled. I actually found better results with Jumbo frames reading/writing to a Netgear NV+ NAS. The biggest benefit was noticed with writes to the NAS.

Thanks so much for all your help Merlin! You rock...
