The above configuration configures S3100-1 and S3100-2 to listen multicast packets
through their VLAN interface 2, and Quidway3 to advertise multicast packets through
VLAN interface 2. Because S3100-2 does not resides in the same network segment as
Quidway3 does, the former cannot receive multicast packets sent by Quidway3, while
S3100-1 is synchronized to Quidway3 after receiving multicast packets sent by
Quidway3.
Display the status of S3100-1 after the synchronization.
