Hi @praveenrk1989
The Operational System should hide it for you. For example, WLC does it. To see this information, you need to enter a special command. If SO (IOS) does not hide this, there´s nothing you can do.
If your device support SNMPv3 then go for it. This version does not rely on community for security.
