ATM Port

The ATM Port object describes a port (physical interface) on an ATM communications card.

Each ATM Port object is a child of an Adaptor object with adaptor type PB1000, PB2000, or PB4000. If the Adaptor object has its Protection mode field set to Backup, this object appears only on the VP3510 or MG3510.

In the EMS System Explorer, the name shown for each ATM Port indicates

For example, 'ATM Port (Controller A, Slot 1, Port 1)'.

In general, you will add ATM Port objects using the "create all ports" action on the parent Adaptor object, and should not need to create them individually.


The Deactivation mode option applies only in a VP3510 or MG3510. For ATM Ports in a VP3500 or MG3500, the deactivation mode for an ATM Port is always Normal, and so there is no Deactivation mode option. Quiesce mode deactivation is available on the associated Fault Tolerant ATM Port.


Parameter

Access

Description
Port number Create An identifier for this ATM Port. The valid port numbers depend on the parent adaptor type, as follows.
  • A PB1000 adaptor has one child ATM port, with port number 1.
  • A PB2000 adaptor has two child ATM ports, with port numbers 1 and 2 (corresponding to the two physical ATM ports on the adaptor card).
  • A PB4000 adaptor has one child ATM port, with port number 8.
Additional information Change A text field that can be used to store information about the ATM Port. This field is optional; you can supply up to 64 characters of free-form text. The text wraps to the width of the field on screen, or you can use the Enter key to force linebreaks.
Description Read only Information about the controller, chassis slot number and port number associated with this port.
Line status Read only Specifies the line status of the ATM Port. One or more of the following values may be set:
  • Sonet LOS
    Loss of signal (signal amplitude has dropped below prescribed limits for a period of time).
  • Sonet LOF
    Loss of frame (OOF state persisting for a period of time).
  • Sonet LOP
    Loss of pointer (consecutive occurrences of conditions that are deemed to cause the value of the pointer to be unknown).
  • AIS
    Alarm indication signal (a remote fault is affecting data that would otherwise be received at this port).
  • RDI
    Remote defect indication (a remote fault is affecting data being transmitted from this port).
  • Path AIS
    Alarm indication signal, but specific to a more remote failure in an optical network.
  • Path RDI
    Remote defect indication, but specific to a more remote failure in an optical network.
Deactivation mode Change This field appears only in a VP3510 or MG3510. Specifies how child objects should be deactivated when deactivating this object. Values:
  • Normal (default)
    Shut down child objects normally before deactivating the port.
  • Quiesce
    Deactivating the port in quiesce mode will wait for all existing child objects using the port to be shut down before deactivation. No new child objects using this port will be accepted during this deactivation period.
  • Abort
    Deactivate the port and all its child objects immediately. (This may result in errors at remote systems.)
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 Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero.
Attention Required alarm events Read only / Reset Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required.
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 Attention Required alarm events was last reset to zero.
Diagnostics - logging - log level Change This field appears only in a VP3510 or MG3510. 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 This field appears only in a VP3510 or MG3510. Specifies whether API tracing is enabled for this object. Values:
  • True
  • False (default)
Diagnostics - API trace - trace tag Change This field appears only in a VP3510 or MG3510. 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:
  • 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.
  • Activating
    Activation is in progress.
  • Deactivating
    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.
