Configuring the WTR timer
When a protection switching event occurs on a station due to link failure, the station enters automatic
protection state. After the link recovers, the station enters the idle protection state. The WTR timer defines
the delay that a station transits to the idle protection state after entering the automatic protection state.
To configure the WTR timer:

Testing connectivity between RPR stations
You can use Echo Request/Echo Response messages to test the connectivity between two stations and
locate failure points if any. The connectivity between the current station and the destination station is
considered as normal if the connection between the two stations is normal on both the sending ringlet
and the receiving ringlet. The destination station should be able to receive the Echo Request messages
that the current station sends along the specific ringlet, and the current station should be able to receive
the Echo Response messages that the destination station sends along the specific ringlet. Otherwise, the
connectivity between the current station and the destination station is considered as having failed.
To test the connectivity to a specific RPR station:

By default, five Echo Request
packets are sent. The default ringlet
that sends Echo Response packets
and Echo Request packets. The
timeout time is 10 milliseconds.
NOTE:
If neither the sending ringlet nor the receiving ringlet is specified, the default ringlet in use is used for
transmitting Echo Request packets and Echo Response.
