In the last year I've worked for two companies, each running Ciscoworks LMS2.6 and in each company I've experienced the same problem. When trying to view a 2800 series router in ciscoview the message below appears.
Can't find applicable device package for x.x.x.253.
Am I right in thinking that cisco have not provided a device package for this router. If anyone knows if there is a device package for this router I'd be greatful if you'd let me know.
