Configuring The Tp Timers; Configuring The Wtr Timer; Testing Connectivity Between Rpr Stations - HPE FlexNetwork HSR6800 series Configuration Manual

To configure the TC timers:
Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Set the TC fast timer.
4. Set the TC slow timer.

Configuring the TP timers

The TP fast/slow timer defines the fast/slow interval at which TP frames are sent. When a station
starts initializing or detects a topology change, nine TP frames are sent at the fast interval. When the
ring topology is stable, the station begins to send TP frames at the slow interval.
To configure the TP timers:
Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Set the TP fast timer.
4. Set the TP slow timer.

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:
Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Set 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
