Configuration restrictions and guidelines
When you configure a Reth interface, follow these restrictions and guidelines:
You cannot assign member interfaces to a Reth subinterface.
You can assign a maximum of two member interfaces to a Reth interface. The member interfaces must have different priorities.
As a best practice, assign interfaces of the same type and same speed to a Reth interface.
You cannot assign subinterfaces or interfaces that have subinterfaces to a Reth interface if the Reth interface has Reth subinterfaces.
You can assign an interface or subinterface to only one Reth interface.
Do not assign two subinterfaces of the same interface to a Reth interface. If the members of a Reth interface are subinterfaces, make sure the subinterfaces terminate packets with the same VLAN ID. For more information about VLAN termination, see Layer 2—LAN Switching Configuration Guide.
Do not specify a Reth interface as the outgoing interface in IPv6 static neighbor entries when the member interfaces contain subinterfaces. For more information about IPv6 static neighbor entries, see Layer 3—IP Services Configuration Guide.
Before you delete a Reth interface, make sure all its member interfaces have been removed.
