Transport Admin State, Operational Status, and Operational Reason

Table 5-2 shows the possible values that may appear in the Operational Status and Operational Reason fields of the Transport Manager > Maintenance > Transport page, and shows the relationship between the Transport Admin States, Operational Status, and Operational Reasons.

The Admin State tells the MP server what protocol state the Transport should be in. If the Transport protocol state does not match what is expected for the Admin State, the MP server actively tries to resolve the problem until the Admin State and the protocol state match.

The Operational Status is either Up or Down.

• Up indicates that the Transport is ready for M3UA signaling.
• Down indicates that the Transport is not ready for M3UA signaling.

  If the Operational Status is Down, the Operational Reason provides information about why it is Down.
