RouterOS Beginner Basics

We have purchased recently cloudcore router (CCR1016-12G) with version 6 ,in these we are facing ICMP issue, Lan side gateway getting huge latency and packet loss when customer are browsing .Please help me out from this issue

2

give us more info about this issue. how are you measuring this latency? what is the configuration of the device? how are the customers connected (through a switch?)

thanks for respond

i am using only hotspot server
x86 on v5.2 running good with this code
now i upgrade to ccr1016 v6.1, traffic is there on counters . but ping is vary at Clint max limit reached

i need ping gateway : 0ms irrespective of Clint bandwidth .

in v5.2 - working with this code
[admin@hotspot] /ip firewall mangle> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=prerouting action=mark-packet new-packet-mark=icmp-in passthrough=yes
protocol=icmp in-interface=ether2

1 chain=postrouting action=mark-packet new-packet-mark=icmp-out
passthrough=yes protocol=icmp out-interface=ether2
[admin@hotspot] /queue tree> print
Flags: X - disabled, I - invalid
0 name=“queue1” parent=global-in packet-mark=icmp-in limit-at=0 queue=default
priority=8 max-limit=10M burst-limit=0 burst-threshold=0 burst-time=0s

1 name=“queue2” parent=global-out packet-mark=icmp-out limit-at=0
queue=default priority=8 max-limit=10M burst-limit=0 burst-threshold=0

now in ccr 1016 v6.1…

[admin@RouterOS] /ip firewall mangle> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=prerouting action=mark-packet new-packet-mark=icmp in
passthrough=yes protocol=icmp in-interface=ether2

1 chain=postrouting action=mark-packet new-packet-mark=icmp out
passthrough=yes protocol=icmp out-interface=ether2
[admin@RouterOS] /queue tree> print
Flags: X - disabled, I - invalid
0 name=“queue1” parent=global packet-mark=icmp in limit-at=0 queue=default
priority=8 max-limit=10M burst-limit=0 burst-threshold=0 burst-time=0s

1 name=“queue2” parent=global packet-mark=icmp out limit-at=0 queue=default
priority=8 max-limit=10M burst-limit=0 burst-threshold=0 burst-time=0s

traffic is showing on counters, but gateway ping is very high at clint bandwidth reached.

plsssss tell me what else config in V6.1



thanks in advance

Usual setup needed to priority ICMP traffic - make 2 marks one ICMP other not-ICMP and prioritize ICMP using limit-at and max-limit.
