Trying to import Cisco Log files

I’m attempting to use Grafana/Loki/Alloy to import Cisco logs into my Grafana dashboards. When allow received a message I get this error:

level=warn msg=“error parsing syslog stream” component_path=/ component_id=loki.source.syslog.cisco err=“expecting a version value in the range 1-999 [col 8]”

Does anyone have the steps needed to import standard cisco syslog format messages into the system?

Thanks
