Microwave backhaul service associations

Composite services

A composite service is a set of linked services. Composite service functionality supports complex applications that require a combination of services, such as VLAN connections to a VPLS service. The composite service provides the functionality to combine an L2 backhaul service created on the MSS1 Wavence node with an L3VPN service having radio as SAP that was created on the MSS8/4 CorEvo node that has the same VLAN ID.

You can also configure a composite service with a microwave backhaul service on a Wavence, and a VPLS service on a 7210 SAS or 7750 SR. See Chapter 16, Wavence composite service for more information about configuring a composite service.

Wavence element manager interworking

Table 15-1, Wavence element manager interworking lists the impact on the microwave backhaul services when the modifications are done in a Wavence element manager.

MAC address

Table 15-2, MAC address lists the conditions under which the MAC address is automatically calculated.

Table 15-2: MAC address

Connection		MAC Address
TDM port to TDM port connection		NFM-P automatically calculates the MAC address
TDM to Ethernet port connection and the Ethernet access port does not have a physical link in the NFM-P	End node (source or destination node) has LAG to LAG ring port and Ethernet as access port	NFM-P prompts you to enter the peer MAC address
	End node (source or destination node) has LAG to Ethernet ring port Ethernet as access port	NFM-P prompts you to enter the local MAC address
	End node (source or destination node) has Ethernet to Ethernet ring port and Ethernet as access port	NFM-P prompts you to enter the local MAC address
Ethernet access ports have physical link in the NFM-P		NFM-P automatically calculates the MAC address. NFM-P automatically calculates the unicast MAC address of neighboring node, which is not part of service, and populates the MAC address also in the ring nodes.
VLL-VLAN heterogeneous ring configuration		You need to enter the MAC address as NFM-P does not calculate the MAC address for heterogeneous configurations.

Service-in-service

NFM-P supports the association of microwave backhaul services with a service tunnel. See “Service tunnels” chapter in the NSP NFM-P Classic Management User Guide for more information about associating a service with a service tunnel.

NFM-P supports autodiscovery for service-in-service associations created with the Wavence. Service-in-service refers to a transport service that carries services for network routers. Autodiscovery allows NFM-P to automatically associate a transport service with a service tunnel when a physical link is created between the Wavence and a non-Wavence NE. Service faults generated on either of the associated services become cross-correlated in the NFM-P.

Note: Service-in-service autodiscovery does not overwrite a service that is already associated with a service tunnel. However, users can manually overwrite an automatic association with another service. Only one service can be associated with a service tunnel.

Note: If the physical link between the Wavence and the network router is removed, the NFM-P automatically disassociates the service from the service tunnel.

Service state

NFM-P calculates the service state under the following conditions:

All of the service objects are deployed
Service is connected
Service is topologically correct

Table 15-3, Operational state lists the operational state of microwave backhaul services.

Table 15-3: Operational state

Scenarios	Operational state
No microwave backhaul service is deployed on the Wavence device.	Unknown
One or more microwave backhaul services are not deployed on the Wavence device.	Unknown
Services include no rings where all of the adjacency port states are up.	Up
Services include no rings where one or more adjacency port state is down.	Down
Services include one or more rings. See Operational state of services that include one or more rings.

Operational state of services that include one or more rings

The operational state is down when the non-ring adjacencies are down. In Figure 15-1, Multiple segments on a single ring, if [A, B] and [C, D] go down, the ring is still operational as only one segment is affected. If [A, B] and [F, E] go down, the ring is down as multiple segments are affected and a ring termination site is no longer reachable.

Figure 15-1: Multiple segments on a single ring

Protection types and Wavence service status

In-service protected Radio links are represented as green links on the Physical topology map; standby Radio links are shown as blue links. The status of a Wavence service, spanning over any protected link, does not depend on the status of the link. The status of the service depends on the Radio direction operative status. See the following table for more information about the service status.

Notes:

If the Radio direction operative status is Up, the services are not affected. If the Radio direction operative status is down, the services are affected. The traffic status is Rx operative Up, if the status is Up for all the protection types (EPS and RPS). The traffic status is Tx operative Up, if the status is Up for all the protection types (EPS and TPS).
