Cisco filebeat module not listening on port as configured

Alas, still no.

I was poking around in the GUI, and I see there's an error message related to the Cisco module:

GoError: could not find delimiter: `` in remaining: `
`, (offset: 0)`Preformatted text`

Someone else had this issue, so I'll poke around where he was directed: Error with Cisco module for filebeat
