Cisco Aironet 1200 - MIBS question

theodionys · ‎07-23-2007

firmware installed 123-8.JEB

Hello,

I use NET-SNMP to take information from AP's database agent.

I want the following information:

client rates (Mbps) - the current rate of

every client connected to the access point. For example for 3 clients -> 1Mbps,5.5Mbps, 11Mbps

I have searched all the supported MIBS from Cisco's website but i cant find anything...

Do i miss something??

Can you help plz...

Best regards,

Theodoros Dionysiou

Hi Theodoros,

I think the closest you're going to get is this object:

.1.3.6.1.4.1.522.3.12.5.1.14

awcDot11TpFdbPreferredTxRate OBJECT-TYPE

-- FROM AWCVX-MIB

SYNTAX UInteger

MAX-ACCESS read-only

STATUS Current

DESCRIPTION "The transmission rate at which a packet should currently be transmitted from an AP to this Station.

This rate does not carry information about whether or not the rate is in the Basic Rate Set (i.e. bit 0x80 is never set)."

::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1) aironet(522) awcVx(3) awcForwardTbl(12) awcDot11TpFdbTable(5) awcDot11TpFdbEntry(1) 14 }

In my research into this question, I haven't found an object that will specifically (within itself) give the data your asking for in that particular format.

I hope this helps,

-Joe

Are there any MIBS ( MIBS that are supported from different Cisco Access Points ), that will give the information i want?

Thanks , -Teo

CISCO-DOT11-ASSOCIATION-MIB::cDot11ClientCurrentTxRateSet.1."gstam-cisco".'......' = Hex-STRING: 16

.

cDot11ClientCurrentTxRateSet OBJECT-TYPE

SYNTAX OCTET STRING (SIZE(1..126))

MAX-ACCESS read-only

STATUS current

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."

::= { cDot11ClientStatisticEntry 1 }

is this object helpful?

i cant understand the mining : octet string 16?

Hi Theo.

I believe it's a hex value of 16, which converts to 22 decimal. Each number representing 500kbps, so 22 decimal (16 Hex) corresponds to 11M.

Hope this helps.
