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 begins 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 Pause Updates so that you can view the results of your selection during this procedure. You can also click the menu option on the main menu to update the page.
Click on the row containing the transport you wish to block to highlight it.
Click Block.
Block is not grayed out if the Transport's administrative state is already Blocked. Also if collection on the server is not working, all actions (Enable, Block, and Disable) are active to give the user control when the status is unknown. The MP server will simply 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. Block is no longer available.
