Could you please help: what i am doing wrong ?

In order to troubleshoot can you post the output of one of the failing Netscalers?
There shouldn't be any sensitive data in that walk output, but double check to be sure before posting and obfuscate if needed.

Thanks for your comment:

this is the output for this command
#snmpwalk -v 2c -c <Com string> < netscaler ip > .1.3.6.1.4.1.5951.4.1.1.41.8
SNMPv2-SMI::enterprises.5951.4.1.1.41.8 = No Such Object available on this agent at this OID

Seems like SNMP is up on that device, but the "No Such Object available on this agent at this OID" message indicates it has different providers than your other devices.

You could try to walk all of enterprises and see what that yields - it might be telling - maybe.

snmpwalk -v 2c -c <community string> <Netscaler IP> SNMPv2-SMI::enterprises
