This object appears only in a VP3500 or MG3500.
The Fault Tolerant ATM Port object describes a pair of ATM Ports, one on each of two ATM adaptor cards, which are grouped together to provide fault tolerance. The cable for the ATM connection is attached through an MMF splitter which provides access to both adaptor cards from the same cable; see the MetaSwitch VP3500 / MG3500 Network Element Installation and Maintenance Guide for more information. If one port fails (for example because of a problem with the adaptor card or the physical connection), the NE automatically switches to use the other port, so that ATM communications are not affected.

Depending on your system requirements, the NE may contain only one ATM adaptor card instead of two. In this case, Fault Tolerant ATM Port objects are still used (to allow for future expansion), but each object references only one physical ATM Port. |
This object is pre-configured (configuration information is delivered with the NE), and you cannot create or delete it. You can enable the port using the Enable button if it is disabled, and activate it using the Activate button.
Each Fault Tolerant ATM Port object is a child of the Virtual Ports object.
In the EMS System Explorer, the name shown for each Fault Tolerant ATM Port identifies the ATM Ports that are grouped together to provide fault tolerance, for example, 'FT ATM Port: ATM Port (Controller A, Slot 1, Port1) / ATM Port (Controller A, Slot 5, Port 1)'. The ATM Port name indicates
Parameter |
Access |
Description |
First ATM Port | Read only | The first of the two physical ATM Ports making up this fault tolerant pair. |
Second ATM Port | Read only | The second of the two physical ATM Ports making up this fault tolerant pair. If the NE contains only one ATM adaptor card, this is shown as Unassigned. |
Requested primary ATM Port | Change | Specifies which of the two physical ATM Ports you want to use as the active port. (This allows you to force the change-over from one port to the other, rather than leaving the NE to make the change automatically. For instance, if you need to remove the adaptor card that supports the currently active port, you can change manually to the other port before doing so; this avoids generating alarms or error messages when the active port fails.)
Values:
|
Actual primary ATM Port | Read only | Specifies which of the two physical ATM Ports is currently active. Values:
|
Mappings synchronization level | Read only | An indication of how well synchronized the two ATM ports in the pair are. This ranges from 0 (not synchronized) to 100 (completely synchronized). |
Deactivation mode | Change | Specifies how child objects should be deactivated when deactivating this object. Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
Alarm log correlator | Read only | Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero. |
Attend To Dependent alarm events | Read only / Reset | Number of times (since this field was reset) that this object's alarm state has gone to Attend To Dependent. |
Alarm state changed timestamp | Read only | The time at which the Alarm state last changed. |
Alarm events reset timestamp | Read only | The time at which the Attend To Dependent alarm events was last reset to zero. |
Diagnostics - log level | Change | Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
|
Diagnostics - API trace enabled | Change | Specifies whether API tracing is enabled for this object. Values:
|
Diagnostics - trace tag | Change | An optional diagnostics tag inserted into API tracing and PD logging for this object. This tag may include any ASCII characters. |
Requested status | Read only | Specifies whether an administrator has attempted to activate the port. Values:
|
Actual status | Read only | Specifies the current status of the port. Values:
|
