The default destination MAC address of a BPDU on the device is 0180-c200-000A. You can change the destination MAC address in the following range:

•  0180-c200-0004~0180-c200-0007
•  0180-c200-0009~0180-c200-0010
•  0180-c200-0020~0180-c200-002f

        If another device also uses 0180-c200-000A as the destination MAC address of BPDUs, it can communicate with the S2300, S3300, S5300, or S6300. If not, change the destination MAC address on either device to ensure that the two devices use the same destination MAC address for BPDUs.

You can check the destination MAC address by running the display cluster command.
