Hello,
i have a mikrotik crs 326 so i want add 4-6 filter rules if i use bridge filter rules i should except ethernet result as show on https://mikrotik.com/product/CRS326-24G-2SplusRM ?
thanks

Once you start running bridge filters you stop switching through hardware and switch through the CPU so numbers will drastically reduce.

hi,
i have following options enabled :
1. bridge enabled with no filters
2. no ip firewall rules
3. just create some switch rules
4. snmp enabled
so in this case hardware switching works with no problem ?


also i have these rules in my switching tab :
0 switch=switch1 ports=Eth2->VPS-KVM1 src-address=1.2.3.4/32 copy-to-cpu=yes redirect-to-cpu=no mirror=no

1 switch=switch1 ports=Eth2->VPS-KVM1 src-address=1.2.3.4/32 copy-to-cpu=yes redirect-to-cpu=no mirror=no

2 switch=switch1 ports=Eth2->VPS-KVM1 copy-to-cpu=no redirect-to-cpu=no mirror=no new-dst-ports=""

because i need to limit ether2 for specific ips, in this cause with above rules in switching do i have hardware switching ?
thanks

bridge filters make you loose a lot of performance

switch rules dont

switch rules run by hardware at wire speed without CPU usage


i dont think you need to configure redirect to CPU action to allow packets from cpu

" A rule without any action parameters is a rule to accept the packet. "

ok understood,
other features like snmp or bonding or such feature does not cause loose performacne?

snmp uses CPU but only for management purposes, dont affect your traffic performance

CRS 3xx supports bonding by hardware, check this info

ok last question is if i use scripts with scheduler that run script every 10 or 15 seconds (that script only check pps on each interface and shutdown them for 2m if they have more than X pps) is it cause high cpu usages or not ?
thanks

complex scripts who take minutes, hours running consume high % of cpu while running, simple scripts generate unnoticeable cpu usage

in case of switch high cpu usage will not ralentize traffic
