Step2 Click the MAT entry that you want to delete.
Step3 Click Remove.
Step4 In the Delete TDC Entry dialog box, click OK.
Step5 Return to your originating procedure (NTP).
DLP-F371 Change the OSI Routing Mode
Caution Do not complete this procedure until you confirm the role of the node within the network. It will be either
an IS Level 1 or an IS Level 1/Level 2. This decision must be carefully considered. For additional
information about OSI provisioning, refer to the “Management Network Connectivity” chapter of the
Cisco ONS 15600 SDH Reference Manual.
Caution LSP buffers must be the same at all NEs within the network, or loss of visibility could occur. Do not
modify the LSP buffers unless you are sure that all NEs within the OSI have the same buffer size.
Caution LSP buffer sizes cannot be greater than the LAP-D MTU size within the OSI area.
Step1 Verify that all L1/L2 virtual routers on the NE must reside in the same area. This means that all
neighboring virtual routers must have at least one common area address.
Step2 In node view, click the Provisioning > OSI > Main Setup tabs.
Step3 Choose one of the following routing modes:
Intermediate System Level 1—The ONS 15600 SDH performs OSI IS functions. It communicates
with IS and ES nodes that reside within its OSI area. It depends upon an IS L1/L2 node to
communicate with IS and ES nodes that reside outside its OSI area.
Intermediate System Level 1/Level 2—The ONS15600 SDH 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.
Purpose This task changes the OSI routing mode.
