snmpget & signal strength

RouterOS General
1

Hi!

Who knows how I can use snmpget to obtain the signal strength of a unit?

[admin@AP] interface wireless> print oid

Yeah, I did find that one… :sunglasses:

But then why doesn’t the following work?

snmpget -v 1 -c [COMMUNITY_STRING] [IP_ADDRESS] .1.3.6.1.4.1.14988.1.1.1.1.1.4.4

snmpwalk does work on those devices…

Hmm, I now have 1 unit on which it works.

The only difference:

non-working units: RouterOS 2.8.5
working unit: RouterOS 2.8.11


Is there somewhere a (detailed) ChangeLog of RouterOS available…?

I think I’ve located the problem…

I have tested a unit with, and a unit without a license key. On both I’ve done ‘interface wireless print oid’

Then I did ‘snmpget -v 1 -c public [IP_address] [OID]’

The licensed unit returned:

Timeout: No Response from [IP_address].

The unlicensed unit returned:

SNMPv2-SMI::enterprises.14988.1.1.1.1.1.4.4 = INTEGER: -56

Can I conclude from this that when I get a license for a unit I actually lose some functionality…?!? :frowning:

SNMP works with no matter what license, so this shouldn’t be possible. can you send a supout.rif file from the not working router to support@mikrotik.com ?

update: the problem has been confirmed and will be fixed in the next release. :sunglasses:

update to the update: I was told the problem would be fixed in the next release (which would be 2.8.13), but the ChangeLog entry for 2.8.13 says:

What’s new in v2.8.13:

*) fixed problem - PPTP and PPPoE Windows client could disconnect
after about 15 minutes;
*) fixed bridge after reboot proxy-arp problem;
*) fixed crash when bridging fragmented VLAN packets;

So I guess the fix for this will have to wait until 2.8.14…? :confused:
