I have for an RB250GS which has been upgraded from 1.0 to correct the ridiculous bug where you was unable to change the IP address of the switch.
I have a cacti box running on CentOS 5.5 i am using to monitor various devices including a few RB450Gs, RB750s & RB250GS.
The RB250GS does not seem to be reporting its status correctly and some information is missing. Below is what i am getting and what is missing. Hostname = Missing, Location = Missing & Contact = Missing
SNMP Information
System:RB250G
Uptime: 135942946 (15 days, 17 hours, 37 minutes)
Hostname:
Location:
Contact:
Can others confirm they can reproduce this behaviour ? Or is this nothing to do with the RB and an issue with cacti or centos.

Re: SwOS 1.2 not reporting SNMP correctly
I cannot reproduce this problem. What is your SNMP configuration on 250GS?
Re: SwOS 1.2 not reporting SNMP correctly
snmp config on the 250GS is:
Enabled = Ticked (yes)
Community = public
Contact Info = My Name
Location = 192.168.1.11
I am not aware of anywhere else i can configure any snmp details.

Hi,
confirmed on 1.4

Correct SNMP Outut should be:

Re: SwOS 1.2 not reporting SNMP correctly
I've been trying SwOS out at home before we even think about selling it to our customers.... I'm definitely seeing strange SNMP data coming back from SwOS (1.4). Typically:
Data simply not being reported - this is my NAS which typically shifts several GB a day: Data being mis-reported - this is the link downstairs to the media PC, a SIP phone, a couple of PCs and the satellite box. Apparently the switch received a little data from them and sent nothing. Again, this link shifts several GB a day: Very strange situations where the OID just disappears (note that the same switch produces continuous data on other ports). This gives gappy graphs. Note that this PC actually shifts more data than the little data in the graph actually indicates: All in all, it's reasonably safe to assume that SNMP in SwOS 1.4 is well and truly borked and is completely unreliable.

Re: SwOS 1.2 not reporting SNMP correctly
Hi,
this is not correct, the snmp counters are working correctly (attention 32bit only, so poll often, if you have much traffic)
BUT: There is a bug in the bandwith values, which are sent from the switch, so your monitoring asumes, that max bandwith is 150 bytes or so, therefore you are getting such crappy graphs. Correct this max bandwith setting in your monitoring app and you will get graphs as you expect
I have an created a thread with bugs and feature requests at: http://forum.mikrotik.com/viewtopic.php?f=17&t=49646
Have a look here for an example regarding the snmp bug for max bandwith.
Hope this helps you,
Ronny

Re: SwOS 1.2 not reporting SNMP correctly
Hi,
andthis is not correct
So I was correct then - SNMP is borked. It's just that the borkedness can be overcome with a manual tweak...There is a bug in the bandwith values
Re: SwOS 1.2 not reporting SNMP correctly
yeah you`re right sorry, i am not a native english speaker hehe
As long as such little bugs can be fixed with little effort, for me this is not borked. But everybody has different meanings on this.
But i agree, such easy stuff, should be fixed quickly, i did not think, that this takes so much time ...

Re: SwOS 1.2 not reporting SNMP correctly
Thank you very much for your reports.
What should we do to reproduce the same problem?
I have configured similar settings to my SwOS, HostName/Location/Contact are always reported by SNMP.

Re: SwOS 1.2 not reporting SNMP correctly
Hi sergejs,
these values are reported everytime, but with a false id:
false statement (at least in actual version 1.4: (.1 at the end)
SNMPv2-MIB::sysContact.1 = STRING: rcmcronny
SNMPv2-MIB::sysName.1 = STRING: MikroTik-250GS
SNMPv2-MIB::sysLocation.1 = STRING: RoomA
correct statement should be: (.0 at the end)
SNMPv2-MIB::sysContact.0 = STRING: rcmcronny
SNMPv2-MIB::sysName.0 = STRING: MikroTik-250GS
SNMPv2-MIB::sysLocation.0 = STRING: RoomA
As there is no .0 ID for these values, cacti or any other snmp solution will not display these informations. (Thats what the Topic starter means ).
Please have a look at my sum post for bugs and features, if you can give some feedback on these, it would be great
