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 GE ports, Layer-2
XGE ports, or Layer-2 aggregate interfaces and cannot be member ports of any aggregation group,
service loopback group, or smart link group.
z
After configuring a Layer-2 aggregate interface as an RRPP port, you can still assign ports to or
remove ports from the aggregation group corresponding to the interface.
