DLP- F362 Provision or Modify TARP Operating Parameters
•Intermediate System Level 1/Level 2—The ONS 15600 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.
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).
DLP-F362 Provision or Modify TARP Operating Parameters
Purpose | This task provisions or modifies the Target Identifier Address Resolution |
| Protocol (TARP) operating parameters including TARP PDU propagation, |
| timers, and loop detection buffer (LDB). |
Tools/Equipment | None |
Prerequisite procedures | DLP-F181 Log into CTC, page 16-34 |
Required/As needed | As needed |
Onsite/Remote | Onsite or remote |
Security Level | Superuser only |
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 This 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 This parameter is only used when the Node Routing Area is provisioned to Intermediate System Level 1/Level 2.
