Configuration Flow for a Composite Service Consisting of E-Line and E-LAN Services

Configuration Flow for a Composite Service Consisting of E-Line and E-LAN Services

This section describes how to configure a composite service consisting of E-Line and E-LAN services, including configuring service information, ports, and protection schemes.

Figure 3-42 shows the flowchart for configuring a composite service consisting of E-Line and E-LAN services.

Figure 3-42  Flowchart for configuring a composite service consisting of E-Line and E-LAN services

Table 3-225 provides details about operations in the flowchart.

Table 3-225  Process of configuring a composite service consisting of E-Line and E-LAN services
Step Operation Remarks
1 Configuring a UNI port (when the UNI port is an Ethernet port) Setting the General Attributes of Ethernet Interfaces

Required. Set parameters as follows:

  • Set Enable Port to Enabled.
  • Set Port Mode to Layer 2.
  • Generally, set Encapsulation Type to 802.1Q. When packets do not need to be distinguished according to their VLAN tags, set Encapsulation Type to Null.
  • Set Working Mode to the same value as on the peer Ethernet equipment. Generally, retain the default value Auto-Negotiation for Working Mode.
  • If jumbo frames do not need to be transmitted, retain the default value 1620 for Max Frame Length (byte). If jumbo frames need to be transmitted, set Max Frame Length (byte) to the maximum length of the jumbo frame to be transmitted.
Setting the Layer 2 Attributes of Ethernet Ports

Optional. Set parameters as follows:

  • Set Tag according to the types of packets from the peer equipment.
    • If all packets are tagged frames, set Tag to Tag Aware.
    • If all packets are untagged frames, set Tag to Access.
    • If both tagged and untagged frames are received, set Tag to Hybrid.
  • When Tag is set to Access or Hybrid, set Default VLAN ID and VLAN Priority for the untagged frames. Set VLAN Priority based on the QoS plan.
Configuring Flow Control

Optional. Set parameters as follows:

  • Generally, PSN uses QoS policies to prevent link congestion. By default, retain the default value Disabled for Auto-Negotiation Flow Control Mode and Non-Autonegotiation Flow Control Mode.
2 Configuring the DCN Function for a Port

Optional. Perform this operation only when the UNI port is an Ethernet port. Set parameters as follows:

  • The UNI port connects to external equipment and does not need to transmit inband DCN information. Therefore, set Enable Port to Disabled for the UNI port.
3 Configuring the NNIs for Ethernet Services Carried by Static MPLS Tunnels Required. Set parameters as follows:
  • Set Port Mode to Layer 3.
  • Set Enable Tunnel to Enabled.
  • Set Specify IP Address to Manually, and set IP Address and IP Mask according to the service plan.
4 Configuring MPLS tunnels Configuring an MPLS Tunnel

Required. Set MPLS tunnel parameters according to the service plan. For details on how to manage MPLS tunnels, see Managing MPLS Tunnels.

Configuring tunnel OAM
NOTE:

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

Configuring MPLS Tunnel OAM
NOTE:

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

Optional. Set parameters as follows:

  • Set OAM Status to Enabled.
  • Set Detection Mode to Manual.
  • Set Detection Packet Type to FFD.
  • Set Detection Packet Period(ms) to 3.3.
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.
Configuring Tunnel APS

Optional. Set tunnel APS parameters according to the service plan. For details on how to manage tunnel APS groups, see Managing Tunnel APS Protection Groups.

NOTE:

Tunnel APS is not used, select PW APS for service protection. For the configuration of PW APS, see Configuring PW APS.

5

Required. Set relevant parameters according to the service plan. For details on how to manage Ethernet services carried by PWs, see Managing PWE3 Services.

6

Required. Set relevant parameters according to the service plan. For details on how to manage Ethernet services carried by PWs, see Managing PWE3 Services.

7 Configuring a Composite Service

Required. Set relevant parameters according to the service plan. For details on how to manage composite services, see Managing Composite Services.

8 Verifying the Composite Service Consisting of E-Line and E-LAN Services

Optional. After completing data configuration, check whether the configuration is correct by verifying the configured services.
