IRQ
Sub-menu level: /system resource irq
Menu shows all used IRQs on the router. It is possible to set up IRQ load balancing on mulicore systems by assigning IRQ to specific core.
IRQ assignments are done by hardware and cannot be changed from RouterOS. For example, if all Ethernets are assigned to one IRQ, then you have to deal with hardware: upgrade motherboards BIOS, reassign IRQs manually in BIOS, if none of above helps then change the hardware.
Properties
| Property | Description |
|---|---|
| cpu (auto | integer; Default: ) | Specifies which CPU is assigned to the IRQ.

Read-only properties
| Property | Description |
|---|---|
| active-cpu (integer) | Shows active CPU in multicore systems. |
| count (integer) | Number of interrupts. On ethernet interfaces interrupt=packet. |
| irq (integer) | IRQ identification number |
| users (string) | Process assigned to IRQ |
IRQ Load Balancing
USB
Sub-menu level: /system resource usb
This menu displays all available USB controllers on the board. Menu is available only if at least one USB controller is present.
