Port Management

About the Devices Port Config Page

To access this page, start from the Devices Configuration page, expand the device tree to see the list of devices, expand a device to see the shelf, expand the shelf to see the circuit packs, expand the circuit pack hierarchy to see the ports, and click the port.

The contents of the Devices Port Config page vary depending on the port. In general, ports in the optical network have fewer parameters while transponder ports (tail facility endpoints) have more parameters because transponders operate at both the optical layer and the physical layer.

Tasks You Can Perform

You can use the Devices Port Config page to perform the following actions:

  • View port parameters on TCX1000-RDM20 and TCX1000-ILA devices and on supported tail facility endpoints.

  • Configure parameters on optical ports on TCX1000-RDM20 devices and on supported tail facility endpoints.

  • Enable or disable a port on TCX1000-RDM20 devices and on supported tail facility endpoints.

Field Descriptions

Table 35 through Table 39 show a superset of the fields displayed for the different kinds of ports and transceivers. Not all fields are displayed or are configurable for all ports and transceivers. If a field is grayed out in the user interface page or does not appear at all, then that attribute is not supported for the specified port or transceiver.

Note This document only gives cursory treatment to the various configuration parameters on tail facility ports. Consult the appropriate Junos OS or BTI7800 documentation to see a fuller description of the parameters along with allowed values.

Table 35: Fields in the Devices Port Config Page for Optical Ports

Field

Description

Administrative State

The port’s administrative state:

  • In-Service - laser is enabled

  • Out-of-Service - laser is disabled

    Note: The only effect of setting a TCX1000-RDM20 Ux port out of service is to mask alarms for that port. The laser is not disabled.

You can change the administrative state of TCX1000-RDM20 ports only. You cannot change the administrative state of TCX1000-ILA ports. TCX1000-ILA ports are controlled exclusively by the optical control layer of the proNX Optical Director.

Operational Status

The port’s operational status:

  • Up - port is operating normally

  • Down - port has detected a problem (for example, loss of signal on input) or is no longer processing the incoming signal due to automatic line shutdown (ALS) procedures

This attribute is read-only.

Label

The port label for TCX1000-RDM20 ports.

This is a character string that you can configure to further describe the port. This string is not used by the proNX Optical Director.

  4. To discard your changes, click Reset.

About the Devices Port Threshold Page

To access this page, start from the Devices Configuration page, expand the device tree to see the list of devices, expand a device to see the shelf, expand the shelf to see the circuit packs, expand the circuit pack to see the ports, and click the port. From here, select the interface (OCH, OTU, ODU) from the drop-down list and click Threshold.

Note Not all devices support configurable thresholds. Devices that do not support configurable thresholds do not have the Threshold tab.

The Devices Port Threshold page displays the threshold crossing alert (TCA) configuration for the port. A threshold crossing alert is a configurable warning that triggers when its associated performance monitoring metric exceeds the configured threshold value. TCAs can be configured for both the 15-minute bin and the 24-hour bin. Typically only a subset of the performance monitoring metrics can be controlled using TCAs.

Tasks You Can Perform

You can view and configure the threshold crossing alerts for the selected port and interface.

Field Descriptions

Table 40 through Table 42 explain the fields in the Devices Port Threshold page.

Note This document only gives cursory treatment to router and switch configuration parameters. Consult the appropriate Junos OS documentation to see a fuller description of the parameters along with usage tips and exceptions.

About the Devices Port Historical PMs (Metrics) Page

To access this page, start from the Devices Configuration page, expand the device tree to see the list of devices, expand a device to see the shelf, expand the shelf to see the circuit packs, expand the circuit pack to see the ports, and click the port. From here, click Metrics (in releases 2.2 and lower) or Metrics>Historical PMs (in releases 18.4 and higher).

The Devices Port Historical PMs (Metrics) page allows you view selected metrics.

Note To ensure that the metrics are displayed with the correct timestamps, ensure that the devices are configured to use NTP servers. See About the Device NTP Servers Page.

Tasks You Can Perform

You can use the Devices Port Historical PMs (Metrics) page to perform the following actions:

  • View the performance monitoring metrics for the port.

  • Analyze the metrics using Grafana.

Field Descriptions

Table 43 explains the fields in the Devices Port Historical PMs (Metrics) page.

Table 43: Fields in the Devices Port Historical PMs (Metrics) Page

Field

Description

Time Series

Set the time series or bin length for which you want to display the counters. The counters are collected in 1-minute, 15-minute, and 24-hour bins.

Note: Not all devices support the 1-minute bin.

Time Range

Specify the time period that you want to view.

Entity

Specify the interface from the drop-down list.

Metric

Specify the metric from the drop-down list.

Viewing Historical Performance Monitoring Metrics

Before You Begin

Prerequisites

Note Management network instability might cause the proNX Optical Director to lose one or more historical PM bins. If you see that some PM bins are missing, you can wait for the next scheduled PM collection or you can perform a manual PM collection to retrieve all bins from the device again. See Collecting Metrics from a Device Manually.

Procedure

Use this procedure to view historical performance monitoring metrics (PMs) for a port.

The proNX Optical Director stores collected PMs in a database for 30 days and makes them available for viewing. PM data points older than 30 days are purged from the database. The proNX Optical Director supports the collection and display of 1-minute, 15-minute, and 1-day bins. The actual bins collected and displayed depend on what the device supports. PM points in 15-minute bins are timestamped on the hour and at every 15 minutes thereafter. PM points for the 1-day bin are timestamped at midnight (local time of the machine running the web browser accessing the GUI).

  1. Start from the Devices Configuration page, expand the device tree to see the list of devices, expand a device to see the shelf, expand the shelf to see the circuit packs, expand the circuit pack to see the ports, and click the port. From here, click Metrics (in releases 2.2 and lower) or Metrics>Historical PMs (in releases 18.4 and higher).

    The metrics for the port are displayed in table form.

  2. Select the Time Series from the drop-down list. The available options are 1 Minute, 15 Minute,and 24 Hours.

    Note Not all devices support the 1 Minute bin. If the 1 Minute bin option does not appear in the drop-down list, then the 1 Minute bin option is not supported for the selected device.

  3. Specify the time range.

    Click inside the Time Range box to open a calendar where you can select the time range. You can choose one of the quick selections (Today, Yesterday, Last 7 Days, Last 30 Days) or you can fully customize your range. Ensure that you specify the correct time in addition to the date.

    When you finish specifying the time range, click Apply.

  4. Specify the Entity (typically the interface) from the drop-down list.
  5. Specify the Metric from the drop-down list.
  6. Click the button.

    The table displays a snapshot of the selected metric. To refresh the table at any time, click the button.

    Note The graph displays the selected metric without units. To obtain the units for the selected metric, consult the MIB where the selected metric is found.

  7. To analyze the metrics using Grafana, select the Analyze button. To get started with Grafana, see Grafana.

See the TCX Series Optical Transport System Feature Guide for the list of performance monitoring metrics supported.
