CES Service Configuration Task Flow

CES Service Configuration Task Flow

This section describes the process of configuring UNI-NNI CES services.

Table 3-259 describes the process of configuring UNI-NNI CES services.

Figure 3-58  Process of configuring UNI-NNI CES services

Table 3-259  Configuration flow for UNI-NNI CES services
No. Operation Remarks
1 Creating the network

Required.

Create NEs, configure NE data, create fibers, and configure clocks.

2 Configuring the LSR ID

Required.

  • Each NE requires a unique LSR ID.
  • When the LSR ID is specified for the first time, a warm-reset occurs on the NE but does not affect services. If the specified LSR ID is then changed, no warm-reset occurs on the NE and services are not affected.
  • If a tunnel exists, do not change the LSR ID.
3 Configuring NNI ports in the packet domain

Required.

  • Configure the general attributes of Ethernet ports.
  • Configure the Layer 3 attributes of Ethernet ports, such as tunnel enabling status and IP addresses.

NNI ports in the packet domain are configured for carrying tunnels.

4 Configuring MPLS tunnels Configuring an MPLS Tunnel

Required.

An MPLS tunnel can be configured in per-NE or end-to-end mode. Set tunnel ID, service name, ingress node, egress node, and transit node; set signaling type to static.

Configuring tunnel OAM 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 the parameters of tunnel APS according to the service planning.

NOTE:

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

5 Configuring SDH services

Required.

You need to create SDH services from an SDH tributary board or line board to a TNW1EM10 board.

6 Configuring CES service ports Configuring SDH Ports on Boards

Required.

Retain the default settings for SDH port parameters on the NMS. You can set port names.

Configuring Board Paths

Optional. Set the following parameters:

  • If PW Type is set to CESoPSN, Frame Format can be set to CRC-4 Multiframe or Double Frame as planned. The value CRC-4 Multiframe is recommended for securing transmission quality.

    If PW Type is set to SAToP, Frame Format can be set to Unframe only.

  • Frame Mode is set to 31 for local ports. If Frame Mode is set to 30 for the opposite port, include timeslot No.16 in the service timeslots configured on the local port.
7 Configuring UNI-NNI CES services

Required.

  1. Configure service ID and service name.
  2. Configure service source and service sink.
  3. Configure PWs, including PW type, PW label, and tunnel type.
  4. Configure advanced attributes, including RTP header, jitter buffer time, and packet loading time.
8 Verifying the CES services

Required.

Test CES services at each E1 port using BER testers.
