Thanks, yes one of the issue was snmp version, my script used v-1. now I am using "snmpget -v 2c -c public -t 2 wlc123 mib-2.47.1.1.1.1.11.1 " I didn't get all information I want, I am looking the following information. which mib/mibs I need. WLC model is 4.1.185.0

$IP = '';

$name = '';

$cpu = '';

$model = '';

$OS = '';

$RAM = '';

$phylocation = '';

$firmware = '';

$serialno = '0';

As Joe wrote you can do a snmpget -v 2c on the whole WLC.

You will get all available snmp parameters of the WLC where you can pick your needed mibs.

thank for your response,yes the version issue has been resolved my problem is now. I want pull the firmware information from WLC and added this line on my perl script -"$firmwareresults = `/opt/OV/bin/snmpget -c public -t 2 $IP cisco.local.lsystem.sysConfigName.0 2>&1`;"

with this I am able pull firmware information from half of my wlc however other half respond with this error "wlc123 cisco.local.lsystem.sysConfigName.0 : VARBIND EXCEPTION: No Such Object" is there any better way specifically get firmware info. thanks again for your help!!!

Did you try the OID .1.3.6.1.2.1.47.1.1.1.1.10 ?

yes and I got error, entityMIB.entityMIBObjects.entityPhysical.entPhysicalTable.entPhysicalEntry.entPhysicalSoftwareRev : VARBIND EXCEPTION: No Such Instance" here is my WLC information "System Information

Manufacturer's Name.............................. Cisco Systems Inc.

Product Name..................................... Cisco Controller

Product Version.................................. 4.1.185.0

RTOS Version..................................... 4.1.185.0

Bootloader Version............................... 4.0.217.0

Build Type....................................... DATA + WPS

System ObjectID.................................. 1.3.6.1.4.1.14179.1.1.4.3

Primary Boot Image............................... Code 4.1.185.0 (active)

Backup Boot Image................................ Code 4.0.217.0

so the strange thing is I have 30 all the same model/ however 20 out of 30 is fine with "cisco.local.lsystem.sysConfigName.0" rest 10 of them just keep syaing "No Such Object"

All your WLCs use the same software version and 10 of the 30 don't work?

Very strange!

Did you try to do a snmpget for all mibs on a not working device?

Perhaps the OID for software version has changed between two releases....I don't know....

yes it is strange, I did get other snmpget result from these WLC except the firmware information. ex.

snmpget -v 2c -c public -t 2 wlc123 1.3.6.1.2.1.1.6.0

system.sysLocation.0 : DISPLAY STRING- (ascii): 1st floor

snmpget -v 2c -c public -t 2 wlc123 1.3.6.1.2.1.1.5.0

system.sysName.0 : DISPLAY STRING- (ascii): wlc123

only the firmware re-quest returned with error.Thanks so much for your time!!!

Is it possible to attach a full snmpget of a working WLC and of a not working WLC?
