Allocating bandwidth resources for Ethernet CFM LBM/LBR SAT

Description

Service Activation Testing (SAT) is a critical operational task that is performed prior to service handoff to a subscriber. SAT can be performed up to speeds of 10 Gbps. To support SAT on the NFM-P, you can configure the following GUI objects to facilitate high-speed Ethernet-CFM LBMs (Loopback messages)-to-LBRs (Loopback responses) processing typically used during SAT.

• Use the Service Activation Response parameter on the MEP Properties form to specify if the MEP uses standard bandwidth processing or if additional bandwidth processing is applied for processing service activation requests/stream encapsulated in the ETH-LBM (Ethernet-Loopback message) format. When enabled, additional bandwidth resources are allocated to rapidly respond to this stream of LBM messages; the MEP will not validate any type-length-value (TLV)s, and will not increment or compute any loopback statistics. When disabled, the MEP ETH-LBMs uses standard bandwidth processing. You can configure the Service Activation Response parameter on SAPs, Spoke or Mesh bindings, and Network Interfaces MEPs associated with VLL Epipe and VPLS services.

• Use the LBM Service Activation Responder Info button on the NE Properties form (Globals tab; OAM sub-tab), to execute the “show eth-cfm lbm-svc-act-responder” CLI command. This command displays all the MEPs that have the Service Activation Response parameter enabled.

• The LBM responder is supported for both the service-based MEPs and the MEPs on the router interface.
