Configuration Example (Closed-Ring Networking with a Switch)

This section describes the configuration procedure.

Networking Diagram

As shown in Figure 1, a network is connected to the upper-layer network through a ring network consisting of PC500 devices (NE1~NE3) and a switch (NE4). NE1 and NE3 are edge devices on the upper layer network and are located in the closed-ring network. NE1 and NE3 are directly connected. Normally, the eastbound port 2-EG6P-1(PORT-1) of NE2 is blocked, and services are transmitted by the westbound port 2-EG6P-2(PORT-2) of NE2. If the link between NE1 and NE2 is faulty, the blocked port on NE2 is unblocked so that the service data can be transmitted through the eastbound port 2-EG6P-1(PORT-1) of NE2. The principles for planning edge ports are as follows: In a closed-ring network, two edge ports are deployed on the same edge device on an upper-layer network.

Planning Principle

NE1 NE2 NE3
Creating SEP Protection Instances Instance ID 1 1 1
Set parameters as follows:
  • Set Instance ID, East Port, East Port Configuration Role, West Port, West Port Configuration Role, Control VLAN, Preemption Delay(s), TC Suppression Time Interval(s), and Authentication Type according to the network plan.
  • When setting Control VLAN, note the following:
    • In a SEP segment, the control VLAN is used to transmit only SEP packets.
    • Each SEP segment must have a control VLAN.
    • If different ports are configured with different SEP segments, they can use the same control VLAN.
    • If different ports are configured with different SEP segments, they can use the same control VLAN.
  • Because the switch does not support authentication, set Authentication Type to No Authentication.

Configuring Port DCN Protocols Protocol Type

2–EG6P-1(PORT-1): L2DCN

2–EG6P-1(PORT-1): L2DCN

2–EG6P-1(PORT-1): SuperL2DCN

  • Set Protocol Type of the ports connected to the switch to SuperL2DCN to ensure that the DCN protocol between the devices and the switch is normal.
  • Retain the default value L2DCN for other ports.

Configuring the Port Blocking Mode Blocking Mode

Optimal

- -
In normal cases, a default blocked port is selected on the network. If the default blocked port is not the one required by the user, follow Configuring the Port Blocking Mode to specify the blocked port on the network. Port blocking mode is classified into the following types:
  • Optimal: Specifies the port with the highest priority as the blocked port. The rules for comparing port priority are as follows:
    • Compare port priority. (Port priority is configurable. A larger value indicates a higher priority.)
    • If the port priorities are the same, compare the bridge MAC addresses of the ports. The smaller the value of a bridge MAC address, the higher the priority.
    • If the bridge MAC addresses are the same, compare the port IDs. The smaller a port ID, the higher the priority.
  • Middle: Specifies the port in the middle of an SEP segment as the blocked port.
  • Hop: Specifies the blocked port according to the hop count configured by the user. The number of hops of a primary edge port is 1, and the number of hops of neighbor ports of a primary edge port is 2. The number of hops increases along the direction of downstream neighbor ports of a primary edge port.
  • Name: Specifies the blocked port according to the device name and port ID.

Configure the Blocking Mode as planned. Generally, the default value Optimal is recommended.

NOTE:
You only need to configure Blocking Mode on a primary node.
Configure the port priority user-defined Priority

2–EG6P-1(PORT-1): 64

2–EG6P-1(PORT-1): 128

2–EG6P-1(PORT-1): 64

When Blocking Mode is set to Optimal, to accurately block the required block point, modify the priority of the specified blocked port and ensure that the priority of the port is the highest in the networking.

NOTE:
The higher the value, the higher the priority, ranges from 1 to 128.

2–EG6P-2(PORT-2): 64

2–EG6P-2(PORT-2): 64

Configuring the Preemption Mode Preemption Mode

Manual Preemption

- - The meanings of the values of this parameter are as follows:
  • Non-preemption: After a link fault is rectified, the service transmission direction is not changed.
  • Manual preemption: When a link is faulty, preemption cannot be initiated. After the link fault is rectified, manual preemption can be initiated to restore the original service transmission direction.
  • Delay preemption: After the faulty link recovers and the delay time elapses, services are restored to the original link for transmission.
NOTE:
Only the master node supports the preemption mode configuration.
