How is convergence performance of Layer 2 multicast accelerated on an S series switch?

When the network topology changes, Layer 2 multicast detects the topology change by responding to notification messages of ring network protocols. Layer 2 multicast sends General Query messages in the VLAN where the topology changes to re-collect group member relationships. Ring network protocols include STP, MSTP, RRPP, Smart Link, and SEP. The ring network protocols supported by the switches excluding the S1700 are as follows:
- STP: supported by all switch models
- MSTP: supported by all switch models excluding the S2700SI
- RRPP: supported by all switch models excluding the S1720 and S2700SI
- Smart Link: supported by all switch models excluding the S1720, S2700SI, S2710SI, and S2700EI
- SEP: supported by all switch models excluding the S1720, S2700SI, S2710SI, and S2700EI
