•
End System—The ONS 15310 performs OSI end system (ES) functions and relies upon an
intermediate system (unlocked) for communication with nodes that reside within its OSI area.
Note
The End System routing mode is not available if more than one virtual router is enabled.
•
Intermediate System Level 1—The ONS 15310 performs OSI unlocked functions. It communicates
with unlocked and ES nodes that reside within its OSI area. It depends upon an unlocked L1/L2 node
to communicate with unlocked and ES nodes that reside outside its OSI area.
Step 3 If needed, change the L1 LSP Buffer Size. This adjusts the Level 1 link state protocol data unit (PDU)
buffer size. The default is 512. It should not be changed.
Step 4
Return to your originating procedure (NTP).
DLP-H201 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 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 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)
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).
