| IPv4 Unicast Routing | HW | 7.1 | |
| IPv6 Unicast Routing | HW | /interface/ethernet/switch/l3hw-settings/set ipv6-hw=yes | 7.6 |

| ECMP | HW | Multipath routing | 7.1 |
| Blackholes | HW | /ip/route add dst-address=10.0.99.0/24 blackhole | 7.1 |
| gateway=<interface_name> | CPU/HW | /ip/route add dst-address=10.0.0.0/24 gateway=ether1 This works only for directly connected networks. Since HW does not know how to send ARP requests, | 7.1 |
| BRIDGE | HW | IP Routing from/to hardware-offloaded bridge interface. | 7.1 |
| VLAN | HW | Routing between VLAN interfaces that are created on hardware-offloaded bridge interface with vlan-filtering. | 7.1 |
| Bonding | HW | /interface/bonding Only | 7.1 |
| IPv4 Firewall | FW | Users must choose either HW-accelerated routing or firewall. Firewall rules get processed by the CPU. Fasttrack connections get offloaded to HW. | 7.1 |
| IPv4 NAT | FW | NAT rules applied to the offloaded Fasttrack connections get processed by HW too. | 7.1 |
| MLAG | N/A | ||
| VRF | N/A | Only the main routing table gets offloaded. If VRF is used together with L3HW and packets arrive on a switch port with l3-hw-offloading=yes, packets can be incorrectly routed through the main routing table. To avoid this, disable L3HW on needed switch ports or use ACL rules to redirect specific traffic to the CPU. | |
| VRRP | N/A | ||
| Controller Bridge and Port Extender | N/A | ||
| VXLAN | CPU | ||
| MTU | HW | The hardware supports up to 8 MTU profiles. | 7.1 |
| QinQ and tag-stacking | CPU | Stacked VLAN interfaces will lose HW offloading, while other VLANs created directly on the bridge interface can still use HW offloading. |

The devices below are based on Marvell 98DX224S, 98DX226S, or 98DX3236 switch chip models.These devices do not support Fasttrack or NAT connection offloading
Below are some important features that these devices are missing when compared to other switch models:
- Fasttrack and NAT connection offloading;
- per-VLAN packet and byte counters.
| Info |
|---|
The 98DX3255 and 98DX3257 models are exceptions, which have a feature set of the DX8000 rather than the DX3000 series. |
