1. Configure VLANs.

# Create VLANs on SwitchA and configure related interfaces to allow packets of these VLANs to pass through. The configurations of SwitchB, SwitchC, and SwitchD are similar to the configuration of SwitchA, and are not mentioned here.

5. Enable interfaces on SwitchB, SwitchC, and SwitchD to receive Flush packets.

# Enable SwitchB to receive Flush packets containing an HMAC-SHA256-encrypted password.
[~SwitchB] interface 10ge 1/0/1
[~SwitchB-10GE1/0/1] stp disable
