- Load the filter on an interface in skb (generic) mode with default allow policy:

`sudo xdp-filter load {{[-p|--policy]}} allow {{[-m|--mode]}} skb {{network_interface}}`

- Unload the filter from an interface:

`sudo xdp-filter unload {{network_interface}}`

- Deny traffic to a specific destination port:

`sudo xdp-filter port {{destination_port}}`

- Deny traffic from a specific source IP address:

`sudo xdp-filter ip {{[-m|--mode]}} src {{source_ip}}`

- Deny traffic from a specific source MAC address:

`sudo xdp-filter ether {{[-m|--mode]}} src {{mac_address}}`

- Poll packets and show statistics every 10000 milliseconds:

`sudo xdp-filter poll {{[-i|--interval]}} 10000`
