Note: Blocking a Transport causes a Transport alarm, and possibly alarms for Links, Link Sets, Routes, or node isolation.
When a Transport is put in the Blocked Administrative State, the MP server attempts to bring the Transport to the SCTP Established protocol state and the ASP-DOWN state. The MP server does not attempt to send ASP-UP.
Select Transport Manager > Maintenance > Transport.
The Transport Manager > Maintenance > Transport page appears.
Click the Pause updates check box (lower right corner) so that you can view the results of your selection during this procedure. You can also click Transport Manager > Maintenance > Transport on the main menu to update the page.
Click on the row to highlight the transport you wish to block.
Click the Block button.
The Block button is not grayed out if the Transport's Administrative State is already Blocked.
Also, if collection on the server is not working, all buttons (Enable, Block, and Disable) are active to give the user control when the status is unknown. The MP server will disregard the command if the Transport is already in the selected Administrative State.
A confirmation message appears.
Click OK to confirm.
The Operational Status field shows Blocked.
The Admin state column now indicates when the Transport transitioned into the Blocked status.
If OK is clicked and the Transport has been deleted by another user, an error message appears.
