message clears MAC/ARP table (FLUSH). In fact it is not needed for some network
environment to do FLUSH with every topology change. At the same time ,as a method to
avoid network assault, we allow the network administrator to configure FLUSH mode by
the command
Note:For the complicated network, especially need to switch from one spanning tree
branch to another rapidly, the disable mode is not recommended.
