Currently my company uses Cisco 1811's for our sites which goes through a provider to our primary router a 3825. The existing IP SLAs we have in place are icmp-jitter types, which isn't capturing packet loss. So I have created a new IP SLA to do just that. IP SLA 10 is the existing one, and 30 is the new one. The 3825 has the ip sla responder activated. Yesterday we experience a site which had a rather high percent packet loss when ping'ed (around 8% loss), so I thought it would be a rather good time to test. But it wasn't detecting any packet loss, did I enter something wrong?
Well using ping from the 1811 to the 3825, 1000 times, we would get anywhere from 30 to 80 packet loss. I look at IP SLA stat and shows nothing for packet loss. And yes that 10 is 30, sorry (it's configured correctly as 30 in the router).
Thanks for replying. I have no idea what port the ping command is using (I didn't know you can specify what port ping uses). We have already fixed the packet loss issue (duplex mismatch). But here's the ip sla stat, values under Packet Loss Values were all 0 when we were experiencing packet loss as well.

To further my question in my original post, how would one implement packet loss SLA and send trap to SNMP server when there is packet loss?
EDIT: Today I noticed a site dropping packets, not as much as the one I mentioned before, here is the ping result and ip sla stat:
