Hello,
We are running RouterOS 6.41 on a CCR1036-8G-2S+ and we are having problem with high latency when we ping the router. This is what we are seeing when I ping from a host that is 1 hop away from the CCR,
PING 192.168.11.1 (192.168.11.1) 56(84) bytes of data.
64 bytes from 192.168.11.1: icmp_seq=1 ttl=63 time=1918 ms
--- 192.168.11.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1918.338/1918.338/1918.338/0.000 ms
We are seeing ping times of up to 2000 ms, and at the same time the cpu load is below 2%. The other problem is that this isn't constant, it appears to be random. Most of the time pings to the router take less that 1 ms

When the problem happens it will last for several seconds and not just pings slow down but all traffic passing through the router experience really high delays. I was wondering it anyone has any ideas about what could be causing the problem. This started happening in February and we thought it was a problem with our upstream provider but then we discovered that the router was responding slowly when the latency happens. We don't want to replace the CCR if we don't have to. If anyone out there has ideas about what could be causing this and a fix please let me know.
Re: High latency
Check interface statistics ( uptime, errors, last downtime, duplex ). Also, it could be issue with routing, but we cannot help wthout topology or configuration.
Re: High latency
Why your ttl is changing? If network would be at 1 hop, ttl would be 64 and won't be routable. Make traceroute to gateway, check every interface on every hop, check crc errors on interfaces. If you have fiber cables, check Tx/Rx optical attenuation, if it's lower or higher interface threshold, change or repair fiber cable.
Re: High latency
How did you fix it having same problem...........latency get high to 30s normal outHello,
