Do not change the system MTU to less than the default value of 1950 bytes. The system MTU must be 1950 or jumbo because of a header size increase.

For configuration information, see Configuring Simplified vIST in SMLT topologies or Configuring Simplified vIST in SMLT topologies.

For information about how to configure Simplified vIST with multicast, see Enabling multicast on the switch.
