NVRAM almost full?

[Livin]

I was getting a warning that it was full... I factory reset and that warning is gone but still very full?

I dont have anything in JFFS, formatted it too.

is this normal?

Some information on router model and firmware version might be helpful.

It can be, especially on a 3200. There are options for offloading some things to jffs with recent versions of the firmware.

If you don't have a complicated setup, a factory reset will clear out wasted nvram variables, notably if you've upgraded firmware over a long period of time - old variables can he hanging around.

Ac68... And did a factory reset... That helped but only a little

My AC68 has 43 of 64 K used, and that's with no effort on my part to limit it, so you're beyond my ability to help.

Supply your firmware version and some details about your setup (e.g. Openvpn, https certs, etc.) and perhaps someone will have an idea.

I have the latest merlin... And I don't use anything but regular stuff... No VPN, no apps, nothing. I have about 15 NAT rules and a 3 different SSID, and 30 devices which 18 are ethernet

@Livin - similar issues here. I'm so close to the limit on my AC3200 - 1 or 2k
Actually checking today 65527 / 65536 which is on the verge of a catastrophic failure I'm sure...
I'm factory reset and the saving is fairly low, and short lived.
I have 20-30 systems, only 3-4 statics, 1 openvpn server, though I do use the trend/QOS stuff
Frankly and IMO it's a bit of an Asus #fail
On the upside I'm figuring out if this means I should give up and switch routers (and if "normal" use causes nvram to fail with stock fw that should be warranty/fit for purpose issue IMO), but the 3200 seems otherwise decent, and I'm still experimenting with the Smart Connect which does seem to help with band affinity

380.67 will limit the number of OpenVPN clients to a maximum of 2 on the RT-AC3200, which will save about 3 KB of nvram (just for the empty/default values of the three clients that are removed). A factory default reset might be needed then to remove those three clients (unless you're willing to manually remove the 30-ish nvram settings yourself).

You mean like

for var in `nvram show | grep vpn_client | sed 's/=/ /g' | awk '{print $1}'`
do
nvram unset $var
done

Just saved me nearly 5K

I need to look at what else might be removable, but this is a huge step forward (I don't use any vpn clients) so thanks @RMerlin!

That removed also clients 1 and 2 tho They will be recreated with their default values at some point.

 

[Nigel Jones]

Ah yes of course you're right... I don't use vpn client so just removed them all, but 1,2 will come back after reboot.
Still, thanks a lot for making this change, it will at least save perhaps 2.5-3K
