Configuring RRPP Rings
When configuring an RRPP ring, you must make some configurations on the ports connecting
each node to the RRPP ring before configuring the nodes.
z
RRPP ports, that is, ports connecting devices to an RRPP ring, must be Layer-2 Ethernet
ports, Layer-2 GE ports, Layer-2 XGE ports, or Layer-2 aggregate ports and cannot be
member ports of any aggregation group, or smart link group.
z
After configuring a Layer-2 aggregate port as an RRPP port, you can still assign ports to or
remove ports from the aggregation group corresponding to the port.
