Configuration Flow

Configuration Flow

The flowchart for configuring an ETH PWE3 service differs according to the type of the ETH PWE3 service.

E-Line Services Carried by PWs

You need to configure the MPLS tunnel before configuring the E-Line services carried by PWs.

Table 3-2 describes the procedure for configuring the E-Line services carried by PWs.

Figure 3-8  Flow chart for configuring the E-Line services carried by PWs

Table 3-2  Procedure for configuring the E-Line services carried by PWs
Step Operation Remarks
1 Configuring the UNI (when the UNI is an Ethernet port) Setting the General Attributes of Ethernet Interfaces

Required.

The parameters are set as follows:

  • Enable Port is set to Enabled.
  • Port Mode is set to Layer 2.
  • Generally, Encapsulation Type is set to 802.1Q. When the packets do not need to be distinguished by VLAN tag, Encapsulation Type is set to Null.
  • Working Mode of the UNI needs to be the same as the working mode of the Ethernet equipment on the opposite end. Generally, this parameter takes the default value Auto-Negotiation.
  • When JUMBO frames do not need to be transmitted, Max Frame Length(byte) takes the default value 1620. In other cases, Max Frame Length(byte) is set to the maximum length of the transmitted JUMBO frames.
Setting the Layer 2 Attributes of Ethernet Ports

Optional.

The parameters are set as follows:

  • Tag needs to be set based on the type of the packets that are transmitted from the equipment on the opposite end.
    • If all the packets are untagged packets, Tag is set to Access.
    • If all the packets are tagged packets, Tag is set to Tag Aware.
    • If the packets contain untagged packets and tagged packets, Tag is set to Hybrid.
  • When Tag is set to Access or Hybrid, Default VLAN ID and VLAN Priority need to be set for the untagged frames. VLAN Priority needs to be set based on the planned QoS.
Configuring Flow Control

Optional.

The parameters are set as follows:

  • Generally, the PSN uses the QoS scheme to prevent link congestion. Hence, Auto-Negotiation Flow Control Mode and Non-Autonegotiation Flow Control Mode need to be set to the default value Disabled, unless otherwise specified.
2 Configuring the DCN Function for a Port

Optional.

This operation is applicable only when the UNI is an Ethernet port. The parameters are set as follows:

  • The UNI is used for connecting the external equipment and does not need to transmit in-band DCN information. Hence, Enable Port needs to be set to Disabled for the UNI.
3 Configuring the NNIs for Ethernet Services Carried by Static MPLS Tunnels

Required.

The parameters need to be set according to the service planning.

  • Port Mode is set to Layer 3.
  • Enable Tunnel is set to Enabled.
  • Specify IP Address is set to Manually and IP Address and IP Mask need to be set according to the service planning.
4 Configuring the MPLS tunnel Configuring an MPLS Tunnel

Required.

The parameters need to be set according to the service planning.

Configuring tunnel OAM
NOTE:

Configure MPLS tunnel OAM or MPLS-TP tunnel OAM according to the service plan.

NOTE:

Only OptiX OSN 550 and OptiX OSN 500 support MPLS Tunnel OAM. OptiX OSN 580 only supports MPLS-TP OAM.

Optional.

To ensure protection switching time within 50 ms, set Detection Packet Type to FFD and Detection Packet Interval (ms) to 3.3. The parameters are set as follows:

Configuring MPLS-TP Tunnel OAM

(Optional) The parameters are set as follows:

  • Set OAM Status to Enabled.
  • If all the NEs along a tunnel are Huawei equipment that supports IP-based MPLS-TP OAM, it is recommended that you set MEG ID Type to IP Based, so that you do not need to plan MEG IDs, MEP IDs, and RMEP IDs.
  • If not all the NEs along a tunnel are Huawei equipment that supports IP-based MPLS-TP OAM or if there are special requirements, it is recommended that you set MEG ID Type to ICC Based. In this case, plan MEG IDs, MEP IDs, and RMEP IDs based on the following principles:
    • All the MEPs and MIPs along the same tunnel must have the same MEG ID. MEPs and MIPs along different tunnels must have different MEG IDs.
    • Each MEP ID in an MEG must be unique.
  • It is recommended that you set this parameter to the default value 7.

  • It is recommended that you set this parameter to the default value Adaptive.

    Detection Mode can be set only for ingress nodes on bidirectional tunnels and egress nodes.
  • It is recommended that you retain the default value 0 for both SD Threshold(%) and SF Threshold(%).
  • To suppress a PW fault alarm caused by a tunnel fault on an NE on which an MS-PW is configured, set AIS Status to Enabled.

  • Set CC Packet Interval (ms) as follows:
    • If the CC function is used to trigger APS, it is recommended that you set CC Packet Interval(ms) to 3.33.
    • If the packet transmission delay variation exceeds 3.33 ms, it is recommended that you set CC Packet Interval(ms) to a value greater than the packet transmission delay variation.
    • If the CC function is used to check the tunnel connectivity, it is recommended that you set CC Packet Interval(ms) to 1000.

    CC Packet Interval(ms) can be set only for egress nodes on bidirectional tunnels and ingress nodes.

  • It is recommended that you set CC Packet Priority to the default value 7.CC Packet Priority can be set only for egress nodes on bidirectional tunnels and ingress nodes.
