CCR randomly dropping packets

Posted: Sat Oct 19, 2013 9:33 pm
by jburk
I have the CCR1036-12G-4S - took a new job and it was here in the rack. I am trying to use it as a lab router, my core router is an RB1100AHx2

So the gateway for my PC is my RB1100, and the gateway for my lab machines is the CCR1036. If I initiate a ping from my PC to the side of the CCR facing my PC, I don't drop packets, but if I ping to the other routed interface, my LAB (or any machine in my lab), I randomly drop packets.

I have disabled ALL firewall rules, all NAT rules and all mangle rules. I have made the routing all static. I have confirmed the LACP hashing between switch and CCR, even disabled the LACP and ran on one interface. Not sure where else to troubleshoot.

The pings below were kicked off at the same time from my PC, 172.30.104.134 is the CCR interface on my PC subnet. 172.30.91.254 is the LAB side. (not sure why TTL changed when remote side started pinging)
