Adding hosts like Switch

[nitin]

whenever m trying to add hosts like switch then its show the following error :-

"Bandwidth and Port Status
No ports were detected on the switch. Possible reasons for this include:
The switch is currently down
The switch does not exist at the address you specified
SNMP support on the switch is disabled

Troubleshooting Tip:
If you keep experiencing problems with the switch wizard scan, login to the Nagios XI server as the root user and execute the following command:

cfgmaker --show-op-down --zero-speed=100000000 --snmp-options=:::::1 --noreversedns health [email protected]
Send the output of the command and a description of your problem to the Nagios support team by posting to our online support forum."

After then its monitor only ping service of switch. please help

Have you verified that you have SNMP enabled on the device? Not just that it is supported, that it is enabled. What type of device is this? And what version of SNMP does it use? Have you supplied the correct community string it resides under?
