DLP- A535 Provision or Modify TARP Operating Parameters

Intermediate System Level 1/Level 2—The ONS 15454 performs IS functions. It communicates with IS and ES nodes that reside within its OSI area. It also communicates with IS L1/L2 nodes that reside in other OSI areas. Before choosing this option, verify the following:

The node is connected to another IS Level 1/Level 2 node that resides in a different OSI area.

The node is connected to all nodes within its area that are provisioned as IS L1/L2.

Step 4 If needed, change the LSP data buffers:

L1 LSP Buffer Size—Adjusts the Level 1 link state PDU buffer size. The default is 512. It should not be changed.

L2 LSP Buffer Size—Adjusts the Level 2 link state PDU buffer size. The default is 512. It should not be changed.

Step 5 Return to your originating procedure (NTP).

Step 1 In node view, click the Provisioning > OSI > TARP > Config tabs.

Step 2 Provision the following parameters, as needed:

TARP PDUs L1 Propagation—If checked (default), TARP Type 1 PDUs that are received by the node and are not excluded by the LDB are propagated to other NEs within the Level 1 OSI area. (Type 1 PDUs request a protocol address that matches a target identifier [TID] within a Level 1 routing area.) The propagation does not occur if the NE is the target of the Type 1 PDU, and PDUs are not propagated to the NE from which the PDU was received.

Note The TARP PDUs L1 Propagation parameter is not used when the Node Routing Area (Provisioning > OSI > Main Setup tab) is set to End System.

TARP PDUs L2 Propagation—If checked (default), TARP Type 2 PDUs received by the node that are not excluded by the LDB are propagated to other NEs within the Level 2 OSI areas. (Type 2 PDUs request a protocol address that matches a TID within a Level 2 routing area.) The propagation occurs if the NE is not the target of the Type 2 PDU, and PDUs are not propagated to the NE from which the PDU was received.

Note The TARP PDUs L2 Propagation parameter is only used when the Node Routing Area is provisioned to Intermediate System Level 1/Level 2.

ONS 15454 specifications

Cisco Systems ONS 15454 is a versatile optical networking platform designed to enable service providers and enterprises to deploy and manage robust optical networks efficiently. The ONS 15454 serves as a cornerstone in the evolution of transport networks, featuring various technologies that meet the increasing demand for bandwidth and service quality.

One of the standout features of the ONS 15454 is its support for multiple service types, including TDM, Ethernet, and Wavelength Division Multiplexing (WDM). This capability allows service providers to maximize network resources while delivering a wide range of services, from traditional voice to high-speed data and video.

The ONS 15454 leverages Dense Wavelength Division Multiplexing (DWDM) technology, enabling the transmission of multiple data streams over a single optical fiber. This effectively expands the network's capacity without the need for additional infrastructure, a crucial benefit in today's ever-growing data landscape. The system supports a variety of transponder modules, allowing for flexible scaling and seamless upgrades as bandwidth requirements increase.

Scalability is another key characteristic of the ONS 15454. With its modular architecture, it accommodates a range of interfaces and line cards, making it easier to tailor deployments to specific customer needs. This modularity not only facilitates upgrades but also simplifies maintenance, minimizing downtime and operational costs.

The platform also features advanced management capabilities through Cisco's Optical Network Management system. This allows for real-time monitoring, provisioning, and troubleshooting, ensuring network reliability and performance. The intuitive interface and comprehensive reporting tools enable operators to gain insights into network operations, improving decision-making processes.

Furthermore, the ONS 15454 is built to support optical layer protection features, enhancing network resilience. Technologies such as Automatic Protection Switching (APS) and Optical Supervisory Channel (OSC) ensure that connectivity is maintained even in the event of a failure, crucial for mission-critical applications.

In conclusion, the Cisco ONS 15454 is a powerful optical networking solution that combines flexibility, scalability, and advanced management features. Its support for various services and technologies positions it as an essential asset for organizations looking to build a future-proof network capable of handling increasing data traffic while maintaining high service standards.
