Configuration Flow for the CES Services

Configuration Flow for the CES Services

The configuration flow varies according to the types of the CES services.

Configuration Flow for UNI-UNI CES Services

This section describes the operation tasks for configuring UNI-UNI CES services and the relationships between the operation tasks.

Table 3-245 provides the procedure for configuring UNI-UNI CES services.

Figure 3-52  Configuration flow for UNI-UNI CES services

Table 3-245  Configuration flow for UNI-UNI CES services
Step Operation Remarks
1 Creating the network

Required.

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

2 Configuring CES service ports Setting Basic Attributes of Smart E1 Ports

Required. Set the parameters as follows:

Port Mode is set to Layer 1.

3 Configuring UNI-UNI CES services

Required.

Set service ID, service name, service source, and service sink.

4 Verifying CES services

Required.

Test CES services at each E1 port using BER testers.

Configuration Flow for UNI-NNI CES Services

This section describes the operation tasks for configuring UNI-NNI CES services and the relationships between the operation tasks.

Table 3-246 provides the procedure for configuring UNI-NNI CES services.

Figure 3-53  Configuration flow for UNI-NNI CES services

Table 3-246  Configuration flow for UNI-NNI CES services
Step 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
NOTE:

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

Configuring MPLS Tunnel OAM

Optional. To ensure protection switching time within 50 ms, set Detection Packet Type to FFD and Detection Packet Interval (ms) to 3.3. Set the following parameters:

  • OAM Status is set to Enabled.
  • Detection Mode is set to Manual.
  • Detection Packet Type is set to FFD.
  • Detection Packet Period(ms) is set 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 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 CES service ports Setting Basic Attributes of Smart E1 Ports

Required. Set the following parameters:

Port Mode is set to Layer 1.

Setting Advanced Attributes of Smart E1 Ports

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.
6 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.
7 Verifying CES services

Required.

Test CES services at each E1 port using BER testers.
