I pings different access points with my PC(Windows, Linux) and Mikrotik 3.30 server. Packet size is 1400. From Mikrotik there are many timeouts(60%), but from pc timeout about 1-2%. Why??? Does it mikrotik(packet size 1400, timeout 1000, ttl 64) ping bug or it is wrong parameters of pc ping configuration(-t -l 1400 -w 1000 -i ttl 64)?
Most likely ping uses different path, when it is sent from Linux and MikroTik. Maybe ping from MikroTik hits congested link, where ICMP messages has lowest priority.
Run traceroute to find out the problematic stage.
I set the highest priority(1) on all mikrotik icmp data used in traffic moving. I ping from pc - no timeouts, ping from mikrotik, used in traffic moving has many timeouts. Ping from other mikrotic’s, connected to main mikrotik has many timeouts too. Load of mikrotik processor is about 10%.
What ping is true? Mikrotik or pc? How to see the same ping on pc if the mikrotik’s ping is true.
