Cannot set up I.A. Ring in my network configuration. After I.A. Ring mode is "On" , "storm" makes my switches down.

  1. Disable STP/RSTP/MSTP, for all ports
  2. Disable "Loop protection" function, it will influence the Ring operation.
  3. We have BLP(Bad link protection), so link down, it swap very fast....but if connect cable back...need to wait 10second..it's designed by RD.
  4. Save running configure to start up configure
