60.4 MRPP Troubleshooting

The normal operation of MRPP protocol depends on normal configuration of each s witch on MRPP ring,
otherwise it is very possible to form ring and broadcast storm:

Configuring MRPP ring, you'd better disconnected the ring, and wait for each s witch configuration,
then open the ring.

When the MRPP ring of enabled switch is disabled on MRPP ring, it ensures the ring of the MRPP
ring has been disconnected.

When there is broadcast storm on MRPP ring, it disconnects the ring firstly, and ens ures if each
switch MRPP ring configuration on the ring is correct or not; if correct, restores the ring, and then
observes the ring is normal or not.

In normal configuration, it still forms ring broadc ast storm or ring block, please open debug function
of primary node MRPP, and used show MRPP statistics command to observe states of primary
node and trans fer node and statistics information is normal or not, and then sends results to our
Technology Service Center.
