Configure TARP Timers
TARP timers provide default values and typically do not need to be
changed.
The amount of time that the router waits to receive a response from a
Type 1 PDU, a Type 2 PDU, and a Type 5 PDU can be configured. In
addition, you can also configure the PDU's lifetime based on the num-
ber of hops.
Timers can also be set to control how long dynamically created TARP
entries remain in the TID cache, and how long the system ID-to-se-
quence number mapping entry remains in the loop detection buffer ta-
ble. The loop detection buffer table prevents TARP PDUs from
looping.
In global configuration mode, configure TARP PDU timers, control
PDU lifetime, and set how long entries remain in cache:
1. Configure the number of seconds that the router will wait for a re-
sponse from a TARP Type 1 PDU.
tarp t1-response-timer seconds
2. Configure the number of seconds that the router will wait for a re-
sponse from a TARP Type 2 PDU.
tarp t2-response-timer seconds
3. Configure the number of seconds that the router will wait for a re-
sponse from a TARP Type 2 PDU after the default timer has ex
pired.

4. Configure the number of seconds that the router will wait for a re-
sponse from a TARP Type 5 PDU.
tarp arp-request-timer seconds
5. Configure the number of routers that a TARP PDU can traverse
before it is discarded.

6. Configure the number of seconds a dynamically-created TARP
entry remains in the TID cache.
tarp cache-timer seconds
7. Configure the number of seconds that a system ID-to-sequence
number mapping entry remains in the loop detection buffer table.
