Hi,

I have RB450G with ROS 4.4, my problem is that the CPU % is going from 4%, 16%, 54% 63% -> 100% this is changing all the time
That wouldn't be strange if I would have a lot of traffic going throug the interfaces, but it is not, I have few mbits of traffic, 30mbps max.

On the interfaces I have few bridge, 4 eoip tunnels(is this the reason?), hotspot, dude server, userman

Is there any way to see what is using the CPU?

30 Mbps with eoip etc. is good amount of load on the system.

curently there is 2X 3mbps on eoip tunnel

it is the sam when there is 2X 20mbps over eoip

does vlan use less cpu?

also, vlan have less overhead =)

does hotspot block vlan? I vas testing vlan and it worked all over my network, excep throuhg hotspot interface

does hotspot block vlan?

please someone help me with this

it all depends on configuration. please check how firewall, bridge and hotspot works in manual.
