The error displayed suggests that the device is not enabled to be polled by SNMP, the community string is incorrect, or if it is enabled, it might not be configured to allow the SNMP OID that cfgmaker needs to be polled.

Lets run a snmpwalk command to see if you can get any response from the device. Replace xxx.xxx.xxx.xxx with the IP address and yyyyyyyyy with the community string. What is the Make and model number of the device you are trying to setup?
