+# VPP Dataplane Limitations
+
+VPP Dataplane provides significant performance advantages, but has some
+limitations you should consider.
+
+- **Feature Parity**
+
+  VPP does not support all features available in the Linux kernel dataplane.
+  Some networking features, specific protocols, or services may not be
+  available.
+
+  While VPP supports various interface types similar to the kernel, their
+  capabilities may differ.
+
+- **NIC and Driver Compatibility**
+
+  VyOS currently supports only DPDK drivers for network interfaces.
+  Not all network interface cards are compatible with DPDK drivers.
+
+- **Data Path Limitations**
+
+  If a feature exists only in the kernel dataplane, traffic that uses that
+  feature cannot traverse VPP interfaces. Examples include:
+
+  - Firewall
+  - QoS
+
+  When traffic uses the pure VPP path, it does not reach the kernel, where
+  such features are implemented. Plan how traffic flows through your VyOS
+  instance to ensure it reaches the necessary features.
+
+  VPP provides native alternatives for some features. For example, VPP
+  native ACLs provide basic firewall functionality.
