DLP-G284 Modify the 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 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.
• TARP PDUs Origination—If checked (default), the node performs all TARP origination functions
including:
–
TID to Network Service Access Point (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 are 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 modifies the TARP operating parameters including TARP
protocol data unit (PDU) propagation, timers, and loop detection buffer
(LDB).
