hi
i have 2 rb532 with 2 sr5
signal level is -60
i have a problem of cpu load 100 % on 5 mbps of uplink rate
i am using bridging with wds i can switch the link to ip routing without bridging will this reserve cpu load ?
this is only configuration these routers have?
you can try setting CPU to 333 if it is not there already and check if that solve anything
yes only bridging transparent with wds , when i have 2500 p/s cpu is 100 % , on 532 cpu cannot go more than 266 it is old 532 i tried to make it 333 but cpu goes back to 266
no matter ho old is your RB500 it can be set to 333 (except rev5 that is already set to 400 and there is no need to downlcock that)
after you set it to 333mhz, you have to reboot it, go back into config and set keep-cpu-frequency
Not just reboot - but power cycle…
/system routerboard settings set cpu-frequency=330MHz
/system routerboard settings keep-frequency
power cycle
done
This is a point to point link I would venture to guess.
Turn your logging on and check your logs.
It can be that simple.
Ie If an interface requests an ip from a server on the other side of this link, and the client for whatever reason does not accept it, the client can re-request an ip, and it creates a DOS of sorts which will load down your CPU.
It could be many things, but it comes down to what packets are reaching your routers.
We found similar performance on bridge ptp links - about 8Mbps total (6 up, 2 down) throughput on RB532 with firewall rules uses 95% of CPU at 330Mhz.
Remove all firewall/mangle rules, queues & connection tracking, and the CPU usage drops to around 60%

same link with bridging and wds giving 17 mbps on cpu load 100 %
i switched one board to ap and second to station and used static routing between them i got 23 mbps on tcp as i see ip routing is lesss cpu hungry
