DLP-D166 Provision or Modify TARP Operating Parameters
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 network element (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.
• TARP PDUs Origination—If checked (default), the node performs all TARP origination functions
including:
– TID-to-NSAP resolution requests (originate TARP Type 1 and Type 2 PDUs)
– NSAP-to-TID requests (originate Type 5 PDUs)
– TARP address changes (originate Type 4 PDUs)
Note TARP Echo and NSAP to TID is not supported.
• TARP Data Cache—If checked (default), the node maintains a TARP data cache (TDC). The TDC
is a database of TID to NSAP pairs created from TARP Type 3 PDUs received by the node and
modified by TARP Type 4 PDUs (TID to NSAP updates or corrections). TARP 3 PDUs are
responses to Type 1 and Type 2 PDUs. The TDC can also be populated with static entries entered
on the TARP > Static TDC tab.
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).
