Cisco Aironet wireless access point graph

[mwestern]

Hi,

I've just trying this template and it works well. Thanks.

I'm trying to modify it so i can graph the signal strength as we have 4 aironets in a redundant bridge setup.

I'm wading through the OIDs off the cisco site [http://www.cisco.com/public/sw-center/n ... mibs.shtml] at the moment trying to find anything about signal strength. I see the KarlNet Wireless Transmissions/Levels and i would like to do the same thing for Aironet.

Anybody done this before?

Hi I'm new using Cacti and i'm trying to install this add-on but I don`t know exactly how, also need to know how do I install de MIB in the access point or if I should install it on the server where i've been running Cacti.

Hope someone can help me!!

I did not graph signal strength fromt he Client Association MIB because it would only graph signal strength from one wireless client. Does not give me much information that I would use.

I would rather graph the wireless transmissions in percentage to gather how well the signal strength is of the AP. For example. If you ssh into an AP and run

Code: Select all

that's great information. I wanted to write a script to grab total RX / TX per transmission rate, and gather the percentage of all packets to see if an AP was transmitting at 11mbs 80% of the time (meaning low quality), or maybe 54mbs 80% of the time (great quality).

Sadly after searching Cisco MIBs for a long time, I have not found these values. I have searched RFC MIB's for network devices, but of course those come up blank. The Cisco-Association MIB does not have this. I thought I would find it int he WIRELESS-IF mib, but I could not find those either.

I am wondering if this is the MIB Object you are looking for.?

Parent: cDot11ClientStatisticEntry
Next sibling: cDot11ClientUpTime

Numerical syntax: Octets
Base syntax: OCTET STRING
Composed syntax: OCTET STRING
Status: current
Max access: read-only
Size list: 1: 1..126

Description: This is the set current transmit data rates for
this client. Each client can transmit data at all
of its configured rates. There is a maximum of 126
it can configure to transmit. Each octet contains
an integer value representing one of these 126
rates it is currently transmitting. Each rate shall
be within the range from 2 to 127, corresponding
to data rates in increments of 500 kb/s from
1 Mb/s to 63.5 Mb/s. This value is reported in
transmitted Beacon, Probe Request, Probe Response,
Association Request, Association Response,
Reassociation Request, and Reassociation Response
frames.

I'm getting:

Error: XML: Cacti version does not exist.

When I try to import the xml file. Any suggestions? Running the latest everything (except PHP).

[Phobos182]

This template was Exported from
Cacti-0.8.6f.

You can only import templates from the same version as I understand. An updated version would have to be exported. Since I have not upgraded yet, I wont be able to provide this.

If anybody in this thread has upgraded to "G". Please export it, and post it.

Thanks,

[that_kid]

I'm running "g" and have this working well. I'll export it and post it.

Noob trying to get this running on Win32 ... anyone else have this running?

[Phobos182]

What is the issue with the graph? If you explain the problem, I can probably help you get it running.

Blank Graph?

[Lestat]

I have a blank graph for my Cisco Aironet 350 Acess Point with NaN values. What should I do?

BTW I have correct graphs for interfaces.

[Lestat]

I found that .1.3.6.1.4.1.9.9.273.1.1.2.1.1.1 OID doesn't exist.

[Steve Ollis]

I created a data template called Cisco Aironet Associations - 350, and changed the OID to ..
.1.3.6.1.4.1.522.3.12.1.8.0

Works for me, YMMV

Steve

[Lestat]

Works for me too. Thanks.

[ramneek_kh]

I am running RHEL 4 and cacti-0.8.6f-2.1.el3.rf version for cacti. I am trying to import the Aironet template but getting "cacti-0.8.6f-2.1.el3.rf". Can anyone help here..

~thanks
Ramneek

[loxus]

I've changed the OID since the one included in the template doesnt work. I've changed it to 1.3.6.1.4.1.9.9.273.1.1.2.1.1 as described in ftp://ftp-sj.cisco.com/pub/mibs/oid/CIS ... ON-MIB.oid

But Cacti is still registering it as "NAN".

When I use snmpwalk, I get this:

router:~# snmpwalk 10.1.1.160 -c defaultCommunity -v1 1.3.6.1.4.1.9.9.273.1.1.2.1.1
SNMPv2-SMI::enterprises.9.9.273.1.1.2.1.1.1 = Gauge32: 1

Afaik, that is a clearly statement of the OID returning 1 associated client... Why doesn't this work with Cacti??

I'm using cacti Version 0.8.6c
