l On LSW1 to LSW5, add the interfaces on the ring at the access layer to SEP
segment 1. Configure the roles of GE1/0/1 and GE1/0/3 of LSW1 in SEP segment
1.
l Add GE1/0/2 of LSW2, GE1/0/1 and GE1/0/2 of LSW6 to LSW8, and GE1/0/2
of LSW3 to SEP segment 2. Configure the roles of GE1/0/2 of LSW2 and GE1/0/2
of LSW3 in SEP segment 2.
l Add GE1/0/1 of LSW3, GE1/0/1 and GE1/0/2 of LSW9 to LSW11, and GE1/0/1
of LSW4 to SEP segment 3. Configure the roles of GE1/0/1 of LSW2 and GE1/0/1
of LSW3 in SEP segment 3.
(3) Specify the port to block on the device where the primary edge port is located.
l In SEP segment 1, specify that the port with the highest priority will be blocked.
l In SEP segment 2, specify the device name and port name to block the specified
port.
l In SEP segment 3, specify that the blocked port be selected according to the
configured hop counts of ports.
(4) Configure the preemption mode on the device where the primary edge port is located.
Configure delayed preemption in SEP segment 1 and manual preemption in SEP
segment 2 and SEP segment 3.
(5) Configure the topology change notification function on the edge devices between SEP
segments, namely, LSW2, LSW3, and LSW4.
2. Configure the Layer 2 forwarding function on CE1, CE2, and LSW1 to LSW11.
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
l Preemption mode
l Method of selecting the port to block
l Priorities of the ports in the SEP segment
Procedure
Step 1 Configure basic SEP functions.
1. Configure SEP segments 1 to 3 and configure VLAN 10, VLAN 20, and VLAN 30 as their
control VLANs, as shown in Figure 10-12.
