Viewing Detailed Information for an Interface
MWTM can display detailed information about a selected interface, including its status and other information.
Updates for the interface that are received from the MWTM server are reflected automatically in this window.
To display detailed information for an interface, select the turner beside Nodes in the left pane of the MWTM Main Window. Then select the turner beside a specific node to display its interfaces. Finally, select an interface.
MWTM displays the Interface Details Window.
The Interface Details Window is composed of the following sections:

Speed (Bits/Sec)
Interface speed in bits per second.
Status Information
The Status Information sub-section contains the following fields:
Is Ignored
Indicates whether the interface is Ignored (that is, whether the interface is to be included when aggregating and displaying MWTM status information).
Admin Status
Displays the administrative status of the interface. Status can be:
Unknown—Unknown administrative status
Up —Administratively up
Shutdown—Administratively down
Testing—Administrator is testing the interface
Operational Status
Displays the operational status of the interface. Status can be:

Connect State
(for GSM Abis)Displays the connection state of a GSM interface. States can be:
Connected —The device is monitoring local and remote alarm status.
Disconnected—The system ignores the local alarm status. The local transmitter on the short-haul is disabled. Capabilitymessages are transmitted to the remote describing the provisioning. The system stays disconnected until the remote capabilities are known and the peer state is transitioned to connected.
Send Connect —One or more attempts have been made to connect to remote peer.
Receive Connect —The local-peer has received a connect request from the remote-peer.
Connect Rejected —Connection was rejected.
ACK Connect —The initial connect request was sent and acknowledged by remote-peer. The local-peer is now waiting for a connect request from the remote-peer.
Check Connect —The local peer has reason to believe its remote peer has failed. Additional tests are being processed to verify peer's state.
Connect State
(for UMTS Iub)Displays the connection state of a UMTS interface. States can be:
Initialized —The connection is starting initialization.
Starting—The shorthaul interface is administratively active, but the backhaul interface is down.
Closed—The backhaul interface is active, but the shorthaul is administratively closed.
Stopped—Unable to connect to peer in specified time interval. Additional attempts will be tried based on peer request or restart timers.
Closing—Connection closed by administration request.
Stopping —Connection shut down by peer's Term-Request. Will transition to stopped state.
Connect Sent —Connection request sent to peer.
ACK Received —Connection request sent and acknowledgement has been received from peer. Now waiting for peer's connection request.
ACK Sent —Connection request received and acknowledgement has been sent to peer. Connection request sent and waiting for peer's acknowledgement.
Open —Connection open and available for traffic.
Local Receive Alarm State
Local Transmit Alarm State
Remote Receive Alarm State
Remote Transmit Alarm State
Displays alarm states for UMTS Iub interface. States can be:
Remote Alarm —Indicates a problem at the remote end. The alarm generated by the remote interface in the E1/T1 data stream is sent and no other action is required.
No Alarm —No alarm is present.
Local Alarm —Indicates local interface problem. The interface has not received synchronization from the GSM device. Device stops transmitting backhaul samples.
Received Alarm —Indicates receive problem in the local device. The remote device stops transmitting backhaul data and indicates a blue alarm.
Alarm State Unavailable —Indicates the alarm state is not available. This state only applies to the remote and occurs when the peer connection is inactive.
Redundancy State
Displays information about the GSM Abis or UMTS Iub interface redundancy state. States can be:
Active—Active owner of interface.

Unmanaged
Waiting
Warning
For detailed definitions of each status, see the "Status Definitions for Nodes" section on page A-4.
Last Status Change
Date and time of last change to status.
Status Reason
Reason for the current status of the interface.
For a full list of possible reasons, see the stateReasons.html file:
•
•
If the cell is too small to show all of the status reason, place the cursor over the cell to see the full status reason in a mouse over help popup.
The status reasons are listed in order of decreasing magnitude. If two or more reasons apply, the reason of greatest magnitude is displayed.
If the status reason is Unsupported Configuration, correct the configuration and enter the mwtm cleandiscover command to delete all current network data and begin a clean discovery of the RAN-O network. If the status reason is still Unsupported Configuration, enter the mwtm clean command to restore the MWTM server to a "clean" state, such as would exist after a new installation of MWTM. For more information on the use of these commands, see the "MWTM Command Reference" section on page C-1.
RAN Information
Note
The RAN Information sub-section contains the following fields:
Interface Details: Notes
The Interface Details: Notes section displays:
•
•
•
Interface Details: Recent Events
The Interface Details: Recent Events table displays all recent events associated with the interface, and enables you to perform event-related tasks, such as setting filters and acknowledging events.
To see mouse over help popup for each column in the table, place the cursor over a column header.
If a cell is too small to show all of its data, place the cursor over the cell to see the full data in a mouse over help popup.
You can resize each column, or sort the table based on the information in one of the columns. By default, MWTM displays the following columns: Act , Category, Severity, Time, and Message.
•

Attaching a Note to an Interface
MWTM enables you to annotate an interface, attaching a descriptive string to it.
To attach a note to an interface, right-click the interface in a window, then select Edit > Notes in the right-click menu. MWTM displays the Edit Notes Dialog for an Interface .
The Edit Notes Dialog for an Interface contains the following fields and buttons:
Viewing Notes for an Interface
MWTM enables you to view any notes that have been associated with an interface.
To view a note for an interface, right-click a node in a window, then select View > Notes in the right-click menu. (The Notes option is grayed-out if there is no note associated with the selected node.)
MWTM displays the Notes panel for the selected node, which displays:

Deleting an Interface
After Discovery, the interfaces in your network are known to MWTM and added to the MWTM database. Physically deleting interfaces from your network is not the same as deleting them from the MWTM database. The following sections describe the differences between deleting interfaces from your network, from the MWTM database, and from the MWTM Discovery database, and the procedures for doing so:
•
•
Deleting an Interface from Your Network
If you physically delete a known interface from your network (for example, by powering down a router), it remains in the MWTM database, MWTM labels it Unknown, and it is the system administrator's responsibility to delete it from the MWTM database, if you choose to do so.
Deleting an Interface from the MWTM Database
Typically, you delete an interface from the MWTM database because you have physically deleted the interface from your network. This is the most common reason for deleting an interface from the MWTM database.
If you have physically deleted an interface from your network, and you then delete it from MWTM, it is no longer in the MWTM database, it does not appear in MWTM windows, and it is not discovered when you run Discovery.
Note
To delete an interface from the MWTM database, use one of the following procedures:
•
•
MWTM asks you to confirm the deletion:
•
•
Ignoring an Interface
You can instruct MWTM to ignore an interface. Setting interfaces to Ignored prevents known interface problems from affecting MWTM displays for associated network objects. In effect, you are preventing a known problem from distracting you from other, more urgent network problems.
Note
Also, if you set an interface to Ignored, make a note of the change, and do not forget to reset the interface when the problem is corrected or the maintenance is complete.To set an interface to Ignored, right-click the interface in the left panel, then select Ignore from the right-click menu.
