Transmission errors

RouterOS General
1

We are using InterMapper to monitor our network using SNMP. We are seeing hundreds, sometimes 1000’s of transmission errors/minute on one of our radios, but 0 receive errors. I’m leaning toward poor communication with some of the 40+ customers pulling from that AP, as some people are on CB3s with 50% or less comm qual.
Has anyone seen something like this before?

Seen this with Karlnet. If one karlnet had a semi-poor connection it retransmitting would cause delays causing all the others to retransmit alot also. We have been moving away from karlnet because of this issue we had some with over 25% retransmit rates. Replacing with mikrotik we have been seeing this issue disappearing :slight_smile:

what kind of AP are you using. What other hardware?

hi kcary,

which OIDs you use for monitoring errors? Are they:

/interface print oid

errors-in=.1.3.6.1.2.1.2.2.1.14.6
errors-out=.1.3.6.1.2.1.2.2.1.20.6
discards-in=.1.3.6.1.2.1.2.2.1.13.6
discards-out=.1.3.6.1.2.1.2.2.1.19.6

I would be interested what exactly errors-in and errors-out represent on Ethernet and Wireless interfaces. That could be very interesting.

thnx!

I was told by support these OIDs are not working and they will be removed from MT? I would love to use them if they can be made to work.

these were taken from 2.8.26, as long as I use this version, nobody is going to take them away from me :slight_smile:

I’m just curious - are these the ones that kcary monitors?

From a support email I sent:

Hello Norris,

These oids are not supported and will be removed.

Sincerely,
Eugene

Hey all,

I believe snmp oids are not working for some of the stats on the net
card.
I’m not getting any values back with mrtg nor getif. Maybe only certain

netcards support this or something? I am using Intel Pro 1000 onboard
nics
from the supermicro 5013ci system.

  Code:

  interface> print oid
   4  R name=.1.3.6.1.2.1.2.2.1.2.5 mtu=.1.3.6.1.2.1.2.2.1.4.5

mac-address=.1.3.6.1.2.1.2.2.1.6.5
admin-status=.1.3.6.1.2.1.2.2.1.7.5
bytes-in=.1.3.6.1.2.1.2.2.1.10.5 packets-in=.1.3.6.1.2.1.2.2.1.11.5
discards-in=.1.3.6.1.2.1.2.2.1.13.5
errors-in=.1.3.6.1.2.1.2.2.1.14.5 bytes-out=.1.3.6.1.2.1.2.2.1.16.5
packets-out=.1.3.6.1.2.1.2.2.1.17.5
discards-out=.1.3.6.1.2.1.2.2.1.19.5 errors-out=.1.3.6.1.2.1.2.2.1.20.5

No values can be pulled for packets-in/out, discards, errors, etc. Any
ideas?
