Chapter 3 Building the Network

3.6.1 Setting Up ONS 15501, ONS 15530, and ONS 15540 NEs for Link Discovery

Note An autodiscovered link between two TPs will override previously autodiscovered links and any manual links on any of the TPs.

Note Links are not supported for the Catalyst 6509.

3.6.1 Setting Up ONS 15501, ONS 15530, and ONS 15540 NEs for Link Discovery

Links between ONS 15501, ONS 15530, and ONS 15540 NEs are automatically discovered and displayed, provided that physical topology is properly configured on all ONS 15501, ONS 15530, and ONS 15540 NEs in the network. Each physical topology neighbor of an NE represents a physical link between the NE and its neighbor NE. The ONS 15501, ONS 15530, and ONS 15540 discovery service collects physical topology information and converts it into physical links displayed by CTM.

Links between ONS 15501, ONS 15530, and ONS 15540 devices can be bidirectional or unidirectional. A unidirectional link operates in the context of the transmit or receive side of a fiber connection and is represented by an arrowhead link in the Network Map. For example, an ONS 15501 connected to the transmit side of an ONS 15540 ESP wavelength division multiplexing (WDM) port is represented as a directional link from the transmit side of the ONS 15540 WDM port to the receive side of the

ONS 15501.

Make sure that have you have set up the topology on all of the ONS 15501, ONS 15530, and ONS 15540 NEs in your network, as described in 3.5.1.4 Prerequisites for Adding ONS 15501, ONS 15530, and ONS 15540 NEs, page 3-10.

3.6.2 Overview of Supported Links

Links can be created at different layer rates depending on the card type. See Table 3-8for the links supported between NEs at compatible layer rates. See Table 3-9for the supported links per layer rate.

Note Links can be created for an MDS 9000 or Not Managed/Other Vendor NE only if the NE is in service or under maintenance. Links created for CTC-based NEs are for circuit routing purposes only. Links created for MDS 9000 or Not Managed/Other Vendor NEs are not used for circuit routing.

Note Physical nonroutable links can be created between NEs that are in the same or a different network partition(s).

Links between TXP_MR_2.5G, TXPP_MR_2.5G, MXP_2.5G_10G, TXP_MR_10G, 2.5G_DM, 2.5G_DMP, TXP_MR_10E, or MXP_MR_10E cards are automatically discovered and cannot be manually created. They can exist if:

•The layer rate is OCH.

•Both cards support the same wavelength.

•The links are bidirectional.
