RT-AX88U snmpd - mini Guide

[corgan2222]

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

opkg install mini_snmpd
opkg install snmp-utils

create /opt/etc/init.d/S50mini_snmpd

#!/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

 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.

Read the very first line of post #1.

Is it possible to use/specify a conf file?

@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:

 * opkg_install_cmd: Cannot install package snmp_utils

My router is RT-AC86U with last stable Rmerlin

Unknown package 'snmp_utils'.
Collected errors:
* opkg_install_cmd: Cannot install package snmp_utils

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

 

[Elmer]

So, it's not:

opkg install mini_snmpd
opkg install snmp_utils

It's:

opkg install mini_snmpd
opkg install snmp-utils

instead.

opkg install mini_snmpd

It's:

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.

 

[corgan2222]

argh, dammed..
sorry for that typo. fixed in the first post

 

[DeDragonSlayer]

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.

I'm trying and it installs but the output in snmpwalk is:

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

 

[Chiny91]

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.
