How many devices at most can be deployed in an RRPP ring when RRPP is deployed on an S series switch

For S series switches, primary and secondary ports of the master node send Health packets. If the secondary port periodically receives Health packets, the master node considers the RRPP ring in Complete state and blocks the secondary port to eliminate loops. Health packets are forwarded through the chip, whose forwarding speed is high. Theoretically, an RRPP ring supports unlimited devices. However, when many devices are configured in an RRPP ring, it takes a long time to rectify any link or node fault. It is recommended that a maximum of 16 devices be configured in an RRPP ring.
