Hi everyone!
I use Mikrotik CRS125-24G-1S-2HnD (v. 6.40.5) as L3-core switch in my LAN. I have several VLANs in my network, created on the Mikrotik. Mikrotik is configured as Switch (not bridge).
When users transfer files inside any vlan - everything OK (speed is high), but when users from vlan111 transfer data to the users in vlan177 (and vice versa), then speed is very slow (3-4 mbit/s).
I tried to change Queue type on the interfaces from from only-hardware-queue to ethernet-default, but it not helped. CPU is not busy.
Can anybody help me to solve this issue??
