There is no separated counters for subinterfaces. If you type "show interface summary" will face up with "no separeted counters are stored by subinterfaces" (something like that :))

Hi @sebastien3 ,Did you already read about "list boolean" SLA? We have "and", "or" parameters. In this way, you can test ISP with HTTP, dns, ping, reachability and another stuffs as unique SLA. Maybe that is good for your scenario.Please let me know ...
