as discused in this thread f the normal snmpd crashed on the RT-AX88U.
So i tryed the mini-snmp package from entware, wich runs totally fine. Just want to share, if someone need this.

install mini_snmpd, snmp-utils

Code:
opkg install mini_snmpd
opkg install snmp-utils
create /opt/etc/init.d/S50mini_snmpd

Code:
#!/bin/sh

ENABLED=yes
PROCS=mini_snmpd
ARGS="-i br0,eth0 -D RT-AX88U -L YOUR-LOCATION -c public -C YOUR-EMAIL"
PREARGS=""
DESC=$PROCS
PATH=/opt/sbin:/opt/bin:/opt/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

. /opt/etc/init.d/rc.func
add/replace your Interfaces in the script after -i and replace YOUR-LOCATION and YOUR-EMAIL with your values.

test from different linux pc with installed snmp

Code:
 snmpwalk -v2c -c public 192.168.X.X

This is great, thank you. I was just looking for the SNMP settings, as I swore that my AC68U had it (and it does), but they stripped it out of this AX88U model for some reason.

@corgan2222 thanks for this. Working perfectly with asus merlin 384.13. Running for about a day now with no issues. The only small caveat is that in order to install entware you need a (preferably usb3) key drive permanently in the router, and for some reason that area of this router runs really hot even to the touch (if the key drive has a metal casing you will quickly notice this)

In case anyone is wondering, eth0 is the WAN port. Also, since this router is using kernel >= 4.1, the snmp stats on the WAN port reflect the real thing, i.e. the counters are not impacted by the well known traffic counter issues in kernel 2.6 /proc/dev/net that impacts the RT-AC3100 and similar platforms. One more neat side benefit of migrating to AX88U

Thanks for this. I'm just configuring a new Asus RT-AC86U and also was looking for SNMP. Now I see I have an option to use it moving forward.

I have this error :

Unknown package 'snmp_utils'.

Collected errors:

My router is RT-AC86U with last stable Rmerlin

RT-AX88. Same here - there is NO snmp-utils.

So, it's not:

Code:
opkg install mini_snmpd
opkg install snmp_utils
It's:

Code:
opkg install mini_snmpd
opkg install snmp-utils
instead.

Yes, but it would appear that in post #1 the correct package is actually correctly listed immediately above it ;)

Look, when you set code fragments for copy paste, people do just that. Outside of a code block, some people assume the grammar police use dashes and not underscores and it has nothing to do with actual program name. Be real, correct the mistake, move on.

Thanks for sharing. Before I wasn't even aware that mini-snmp exists.

I set it up on an AX88U and on an old N66U running stock Asus as well. It's a bit limited, as expected, but provides the basic status and traffic information. Now I can check on all my home devices for no reason at all. :)

Have you tried the latest RMerlin 384.18_0 release final yet?

Ah, excellent, thanks for that cracking post. Installed/working in moments on my RT-AC86U with Merlin Firmware Version:384.18 and I now have pretty graphs scrolling around my monitor :) Wonderful.

I've been muttering about the dodgy state of the RT-AC86U for some while, and this has restored some of my early enthusiasm. Obviously mini-snmpd doesn't have all the net-snmp features but it is a vast improvement on nothing.

what do you use to display the graphs?
thanks
