Unable to call splunk-forwarder

Hi All, I installed both splunkforwarder-6.6.2-4b804538c686.i386.rpm and AristaAppForSplunk-1.3.1.swix on Arista 7280 and 4.18.0F software image version. I checked using “show installed-extensions” and both plugins are shown. But it complains of “Invalid input” when I issue “splunk-forwarder”. I issued “show splunk-forwarder” and it says that Administrative Status: shutdown and Operational Status: disabled (no splunk-servers configured). I have also issued “management api http-commands”, “protocol http” and “no shutdown”. How can I get splunkforwarder enabled and running on Arista switch? Thank you in advance.
