I have an older 2811 router running 'c2800nm-advipservicesk9-mz.124-10.bin' in Mexico. Two VWIC2-1MFT-G703 cards are installed for the E1 lines (2Mbt) and combined into a multilink. Getting output drops on the multilink but the serial lines are clean. Odd thing is, I get dropped packets when pinging the multilink. CPU Proc is 7%. QOS is enabled/running.
I have a Cisco TAC case open for the output drops.
Really curious as to how the multilink can fail pings with low proc?
I'm not sure where icmp falls in the mix of your class-maps, so it's hard for me to tell if it's getting classified or dumped into the default queue. I don't see any errors on the interfaces/links at all, so I doubt this is a carrier issue. Are there any other issues that you've noticed outside of losing a packet or two from a ping?
