commands, see VLAN Configuration Commands in the Layer 2 - LAN Switching Command
Reference.

Commands in the Layer 2 - LAN Switching Command Reference.
z Do not enable OAM remote loopback function on an RRPP port. Otherwise, this may cause
temporary broadcast storm.
z It is recommended that you use the link-delay command to enable link status rapid report
function on an RRPP port by setting the physical state change suppression interval to 0
seconds, thus accelerating topology convergence. For more information about the
link-delay command, see Ethernet Interface Configuration Commands in the Layer 2 - LAN
Switching Command Reference.
Configuring RRPP Nodes
z The maximum number of rings that can be configured on a device in all RRPP domains is
16.
z If a device carries multiple RRPP rings in an RRPP domain, only one ring can be
configured as the primary ring on the device and the role of the device on a subring can
only be an edge node or an assistant-edge node.
