Configuring Port Blocking

If you block a port, the port is retained in the operationally down state. If you unblock a port, a port initialization is attempted. When a port is blocked, data and control traffic are not allowed on that port.

Physical Fibre Channel port blocks will continue to transmit an Off-line state (OLS) primitive sequence on a blocked port.

Note     The shutdown/no shutdown port state is independent of the block/no block port state.

Restrictions

You cannot block or prohibit the CUP port (0XFE). If a port is shut down, unblocking that port does not initialize the port.

Detailed Steps

To block or unblock port addresses in a VSAN using Device Manager, follow these steps:

  1. Choose FICON > VSANs.
  2. Select a VSAN ID and click Port Configuration.

    3. You see the FICON Port Configuration dialog box for the selected VSAN.

  3. Check the Blocked check box for the port that you want to block.
  4. Click Apply to save the changes.
