that may not have TARP running, TARP provides a static TARP adja-
cency capability. Static adjacencies are maintained in a special queue.

In global configuration mode, create a static TARP adjacency:

nsap

To stop TARP from propagating PDUs to an IS-IS/ES-IS adjacency
that may not have TARP running, TARP provides a blacklist adja-
cency capability. The router will not propagate TARP PDUs to black-
listed routers.

In global configuration mode, bypass a router not running TARP.

Determine TIDs and NSAPs

In EXEC mode, determine an NSAP address for a TID or a TID for an
NSAP address:

1.

Get the TID associated with a specific NSAP.

nsap

2.

Get the NSAP associated with a specific TID.

To determine the TID, the router first checks the local TID cache. I
there is a TID entry in the local TID cache, the requested information
is displayed. If there is no TID entry in the local TID cache, a TARP
Type 5 PDU is sent out to the specified NSAP address.

To determine the NSAP address, the router first checks the local TID
cache. If there is an NSAP entry in the local TID cache, the requested
information is displayed. If there is no NSAP entry in the local TID
cache, a TARP Type 1 or Type 2 PDU is sent out. By default, a Typ
1 PDU is sent to all Lev el1 (IS-IS and ES-IS) neighbors. If a response
is received, the requested information is displayed. If a response is not
received within the response time, a Type 2 PDU is sent to all L evel1
and Leve l2 neighbors. Specifying the EXEC command

causes only a Type 2 PDU to be sent.

You can configure the length of time that the router will wait for a re-
sponse (in the form of a Type 3 PDU).
