The above configuration configures S7500-1 and S7500-2 to listen to broadcast
packets through their VLAN interface 2, and H3C3 to send broadcast packets through
VLAN interface 2. Because S7500-2 does not reside in the same network segment with
H3C3, S7500-2 cannot receive broadcast packets sent by H3C3, while S7500-1 is
synchronized to H3C3 after receiving broadcast packets sent by H3C3.
View the status of S7500-1 after the synchronization.
