Aruba OS 6.5.4.3 SNMP OID Guide

Hi,

 

I am new monitoring aruba hardware and I would like to monitor it.

 

I am trying to monitor an AP of Aruba, model APIN0315.

 

I am using SNMPv2 and the Aruba OS version is 6.5.4.3

 

I would like to have the SNMP file guide with the OIDs, but in the documentation there is nothing or I dont know to find it: https://support.arubanetworks.com/Documentation/tabid/77/DMXModule/512/EntryId/26664/Default.aspx

 

Some one can help me?

 

Thanks.

Re: Aruba OS 6.5.4.3 SNMP OID Guide

you need to obtain the actual MIB files, which means you need to look in software (not documentation as you have linked) and get the MIB files from there.

 

Aruba doesn't publish MIB documentation any more, you can

a) manually edit the files and look around inside
b) use something like iReasoning mib browser to load the MIBs and inspect
c) sse snmpwalk to walk the entire Aruba MIB and put it into a text file, then inspect the text file.

I have read all the lines that snmpwalk gives me, but there is no nothing that matches with cpu load or free memory.

 

Is possible to get the OID that monitor the CPU load or the free memory from the information that snmpwalk gives me?

 

Thanks.

i suspect you dont have the MIBS loaded correctly

 

root@kali-246:/home/mibs/8.6.0.0# snmpwalk -v2c -cpublic -O0X -mALL -M. 192.168.40.100 aruba | grep -i cpu
AI-AP-MIB::aiAPCPUUtilization[STRING: 80:8d:b7:c4:38:4e] = INTEGER: 2
AI-AP-MIB::aiAPCPUUtilization[STRING: 80:8d:b7:cd:46:74] = INTEGER: 6

I am executing the next command:  #snmpwalk -v 2c -c "my-publyc-key" -m ALL ARUBA-IP > aruba.txt

 

In the file I get, there is no cpu or memory information.

 

If you want, I can send you the file by a private message.

 

Thanks.

Re: Aruba OS 6.5.4.3 SNMP OID Guide

your invocation is wrong, please use the example I posted it should work fine (assuming you have unzipped the MIBs into some directory)

 

you can attach the file here if you want, but again, you're calling snmpwalk wrong

I think that the problem is that I didnt download that MIB file.

 

Where can I download that file? Thanks.

 

Any way, this is my result to the snmpwalk command.

Re: Aruba OS 6.5.4.3 SNMP OID Guide

It may be that you didnt download the MIB (which is fatal), but you also invoked snmpwalk wrong; please use my example not yours (and look at other examples in the forum). You should be able to get the MIBS from the support site - if you don't have login creds then you should contact your partner (or search around on the Internet, some of the opensource NMS projects may have copies).

My aruba os version is 6.5.4.3, I need the the MIB files for that version or the last one? If I need the last one, wich is?

 

Sorry for the late replay.

Re: Aruba OS 6.5.4.3 SNMP OID Guide

there's not a lot of variation in the MIB files across releases, you can use any 6.5.4.x or higher (also the memory and cpu OIDs will be constant over many many releases, you can probably use any 6.5.x)
