Feature Limitations
- Traffic policies containing redirection cannot be applied in the outbound direction.
- Packets forwarded at Layer 2 are redirected to an interface. Packets forwarded at Layer 3 and packets forwarded in unicast mode to a VXLAN tunnel are redirected to the next hop.
- For the CE12800: The action of redirecting packets to an observing interface group is valid for only Layer 2 packets.
- Applying a traffic policy containing redirection to the CPU may affect the system performance. Exercise caution when you apply a traffic policy containing redirection to the CPU.
For the CE12800: When a traffic policy containing redirection is applied to a Layer 2 Ethernet interface, the Layer 2 Ethernet interface can only redirect Layer 2 packets. When a traffic policy containing redirection is applied to a VLANIF interface, the VLANIF interface can redirect both Layer 2 and Layer 3 packets. A traffic policy containing redirection can be applied to a Layer 3 physical interface, but does not take effect.
For CE12800E switches, when a traffic policy containing redirection is applied to a Layer 2 Ethernet interface, the Layer 2 Ethernet interface can only redirect Layer 2 packets. When a traffic policy containing redirection is applied to a VLANIF interface, the VLANIF interface can only redirect Layer 3 packets. A traffic policy containing redirection can be applied to a Layer 3 physical interface, but does not take effect.
For the CE12800: On the device at the VXLAN tunnel egress, all VXLAN packets cannot be redirected to interfaces.
- For the CE12800E: When a traffic policy that defines redirection to a specified interface is applied to a Layer 3 main interface, the redirect-to-interface must be the Layer 3 main interface. On the CE12800E configured with FD-X series cards, a traffic policy that defines redirection to a specified interface cannot be configured on a Layer 3 main interface.
- On the CE12800E equipped with ED-E, EG-E, and EGA-E series cards, URPF check is not performed for redirected packets.
