Configuration Roadmap
The configuration roadmap is as follows:
1. Configure basic SEP functions.
(1) Configure SEP segment 1 on LSW1 to LSW5 and configure VLAN 10 as the control
VLAN of SEP segment 1.
(2) Add all devices on the ring to SEP segment 1, and configure the roles of GE1/0/1 and
GE1/0/3 of LSW1 in SEP segment 1.
(3) On the device where the primary edge port is located, specify that the port with the
highest priority will be blocked.
(4) Set priorities of the ports in the SEP segment.
Set the highest priority for GE1/0/2 of LSW3 and retain the default priority of the
other ports so that GE1/0/2 of LSW3 will be blocked.
(5) Configure delayed preemption on the device where the primary edge port is located.
2. Configure the Layer 2 forwarding function on CE1 and LSW1 to LSW5.
Data Preparation
To complete the configuration, you need the following data:
l SEP segment ID
l Control VLAN of the SEP segment
l Port roles in the SEP segment
