How to read number of clients connected ?

[enrico.becchetti]

Dear All,

I'm a newbie in Cisco Wireless Lan Controller because I've usually used standalone

products, for example Aironet 1100 1200 series and so on but now I'm updating

infrastructure from these old APs to new 1600 and 18500 series with Mobility Express (VWLC). In the past I've used some snmp features to read values from AP: traffic stastistics, users etc. 

Does someone help me to read the numbers of clients connected directly from AP ?

My goal is to pass these informartion to weathermaps to build a chart with these values for each hour of the day.

My old bash script:

#!/bin/bash
AP=$1
snmp=`snmpwalk -v 1 -c public $AP 1.3.6.1.4.1.9.9.273.1.1.2.1.1 2>/dev/null`
if [ $? -gt 0 ];
   then
        users=0
   else
	users=` echo $snmp  | cut -d":" -f4`
fi
echo $users
echo 0
exit

Thank you so much !

Best Regards

Enrico

You can try using OID:

1.3.6.1.4.1.14179.2.1.1.1.38.(APIndex)

And  get the index from SNMPv2-SMI::enterprises.14179.2.1.1.1.2.1 = STRING:

10.21.0.1 is the Virtual Wireless Lan Controller. How I can associate the number of client to each AP?

Thanks again
