Nagios Support Forum

I am trying to monitor a Nexus 9508 and am getting the following output from cfgmaker:

The snmp config for the switch is as follows:

snmp-server user admin network-admin auth md5 0x2f463308349a3ed22a80aefcf0e03687 priv 0x2f463308349a3ed22a80aefcf0e03687 localizedkey
snmp-server user nagios network-operator auth sha 0x6cbcc14e3f7c7a373dcb5b34e71c26913b8accdb priv 0x6cbcc14e3f7c7a373dcb5b34e71c26913b8accdb localizedkey

Please let me know what I am missing.
