Fault Tolerant ATM Port

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 VP3000: 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 VP3000 automatically switches to use the other port, so that ATM communications are not affected.


Depending on your system requirements, the VP3000 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 VP3000), 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 Media Gateway 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 (Shelf A, Slot 1, Port1) / ATM Port (Shelf A, Slot 5, Port 1)'. The ATM Port name indicates

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 VP3000 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 VP3000 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:
  • 1 Use First ATM Port.
  • 2 Use Second ATM Port.
If the VP3000 contains only one ATM adaptor card, this must be set to 1.
Actual primary ATM Port Read only Specifies which of the two physical ATM Ports is currently active. Values:
  • 1 The First ATM Port is active.
  • 2 The Second ATM Port is active.
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:
  • Normal (default)
    Shut down child objects normally before deactivating the object.
  • Quiesce
    Wait for existing child objects to become inactive before deactivating the object, but do not allow any new child objects to be activated.
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention.
  • Attend To Dependent
    Attention Required elsewhere - another object on which this object depends is not operating normally.
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 (UTC) at which the Alarm state last changed.
Alarm events reset timestamp Read only The time (UTC) 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:
  • Level 10 (diagnostics)
  • Level 20 (verbose statistics)
  • Level 30 (verbose operational)
  • Level 40 (statistics)
  • Level 50 (audit)
  • Level 60 (operational)
  • Level 70 (unexpected)
  • Level 80 (error)
  • Level 90 (fatal)
  • Default level (default)
Diagnostics - API trace enabled Change Specifies whether API tracing is enabled for this object. If set to True, the Diagnostics - trace tag must be specified. Values:
  • True
  • False (default)
Diagnostics - trace tag Change The diagnostics tag inserted into API tracing and PD logging for this object. This tag may include any ASCII characters other than whitespace.
Requested status Read only Specifies whether an administrator has attempted to activate the port. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
  • Disabled
    The object has been disabled.
Actual status Read only Specifies the current status of the port. Values:
  • Active
    The object is active.
  • Going Active
    Activation is in progress.
  • Going Inactive
    Deactivation is in progress.
  • Inactive
    The object is inactive.
  • Disabled
    The object has been disabled.
  • Activation Failed
    The object is inactive because an activation attempt has failed.
  • Failed
    The object was active but has failed.
  • Quiescing
    The object is preparing for normal deactivation. It is operating normally but will not accept any new users.
  • Waiting For Parent
    The object cannot be used because its parent object is not yet active.
  • Parent Failed
    The object cannot be used because its parent object has failed.
