Example for Associating MAC-Layer SD Alarms with E-PW APS
In E-PW APS scenarios, MPLS-TP OAM is used to monitor the status of a static single-segment (SS) PW. An E-Trunk is configured to determine the master/backup PE status. This section provides an example for associating MAC-layer SD alarms with E-PW APS.
Networking Requirements
On the public network shown in Figure 1, three PEs belong to the same IGP domain, and static bidirectional co-routed LSPs must be deployed. CE1 and CE2 must reliably communicate through the three PEs on the public network.
Interfaces 1 through 3 in this example represent GigabitEthernet0/1/0, GigabitEthernet0/1/1 and GigabitEthernet0/1/2 respectively.Subinterface1 represents GigabitEthernet0/1/0.1.
Configuration Roadmap
The configuration roadmap is as follows:
Assign an IP address to each interface and configure a routing protocol.
Configure MPLS and public network tunnels.
In this example, a static bidirectional co-routed LSP is established between PE1 and PE2, between PE1 and PE3, and between PE2 and PE3. The required configurations include:
Configure basic MPLS functions and enable MPLS TE.
Configure an MPLS TE tunnel interface.
Configure the ingress and egress for each static bidirectional co-routed LSP.
Bind tunnel interfaces on PE2 and PE3 to static bidirectional co-routed LSPs.
Configure AC dual-homing protection, which requires the following:
- Configure an Eth-Trunk on PE2, PE3, and CE2.
- Configure an E-Trunk on PE2 and PE3 to determine the master/backup status.
Configure PWs in a PW APS/E-PW APS group. This example uses static PWs and requires the following:
Configure a primary PW between PE1 and PE2.
Configure a secondary PW between PE1 and PE3.
Configure a bypass PW between PE2 and PE3.
Configure PW APS/E-PW APS, which requires the following:
Configure a common PW APS instance on PE1.
Configure an E-PW APS instance on PE2 and PE3.
Bind PWs to the PW APS/E-PW APS instances.
Configure MPLS-TP OAM to monitor the PW status, which requires the following:
Create ME instances and bind them to PWs.
Enable CC and CV functions for PWs.
Configure MPLS-TP OAM to monitor the LSP status, which requires the following:
Create an ME instance and bind it to TE tunnels.
Enable CC and CV functions for PWs.
Enable the MAC-layer SD alarm function, configure alarm generation and clearing thresholds, and associate bit error alarms with E-PW APS. These require the following:
- Enable the AIS function globally on PE1, PE2, and PE3.
- Enable the MAC-layer SD alarm function on PE1, PE2, and PE3, configure alarm generation and clearing thresholds, and associate bit error alarms with E-PW APS.
Data Preparation
To complete the configuration, you need the following data:
PEs' interface numbers and IP addresses, and OSPF process numbers
PEs' LSR IDs, tunnel interface numbers and IP addresses, incoming and outgoing tunnel labels, next hop address or outbound interface name on the ingress of each static bidirectional co-routed LSP, and inbound interface name on the egress of each static bidirectional co-routed LSP
L2VC destination IP addresses, VC IDs, VC types, and transmit/receive labels of static PWs
APS instance number on PE1, and roles, local numbers, and remote numbers of the E-PW APS instances on PE2 and PE3
MPLS-TP OAM MEG name, and local and remote MEG IDs
Eth-Trunk number, and E-Trunk LACP system ID and priority
MAC-layer SD alarm generation and clearing thresholds
Procedure
- Assign an IP address to each interface and configure a routing protocol.
Configure an IP address and mask for each interface based on Figure 1. For configuration details, see Configuration Files in this section.
In this example, OSPF is used as an IGP for PE1, PE2, and PE3 to communicate at the network layer. For configuration details, see Configuration Files in this section.
- Configure MPLS and public network tunnels.
In this example, a static bidirectional co-routed LSP is established between PE1 and PE2, between PE1 and PE3, and between PE2 and PE3.
- Configure the ingress and egress for each static bidirectional co-routed LSP.
A static bidirectional co-routed LSP on an ingress can go up only when the LSP name is the same as the tunnel interface name on the ingress. Note that the first letter of the tunnel interface name must be uppercase. This restriction does not apply to transit nodes or the egress.

- Configure the ingress and egress for each static bidirectional co-routed LSP.
- Configure AC dual-homing protection.
- Configure a PW protection group.
This example uses static PWs.
- Configure static PWs.
When configuring a static PW, you must specify the VC ID. If you do not specify the VC ID, the PW cannot be bound to a PW APS instance.
