5.5.3.2 Scenario B – Non-Configured Architecture
In some situations, users can choose not to configure the RPL owner and neighbor node; the
ERPS could still work well under the mechanism by blocking one of the ring ports in the ERPS
ring topology.
As above Figure 5.28, the ERPS is blocked at one of the ring node ports. The blocked port is
chosen by an election mechanism that is decided by the MAC address. Due to the MAC
address is unique; the ERPS will just choose the biggest MAC as the blocking node.
However, the user is still required to enable the RRPS protocol, and assign a dedicated port
number for each uplink port under “Ring Port 0 and 1” but there is no requirement to setting the
role. Figure 5.29, below, shows the configurations as a reference.
After the configurations, press the “Apply” button on the bottom right corner to save the settings.
Note: The port number of “Ring Port 0” and “Ring Port 1” cannot be duplicated.

Caution: Before enabling any ERPS protocols on any of the Ring Nodes, please DO
NOT connect all switches to form a loop (ring) network just yet. There
should be at least one ring port left unplugged until all nodes in the
topology are ready.
