# Terminal monitoring

### 1. Summary

On this page you can make settings for device monitoring.
The device communication status can be monitored by specifying the monitoring target and method.
You can also specify the action to be executed when the device status changes.
Device monitoring settings can be made only from the Web GUI.
Although the contents of the device monitoring settingsare not shown in the CONFIG file, when an operation (such as "erasestartup-config") is performed on the CONFIG file, the same operation isperformed on the device monitoring settings.
If the auto-configure via LLDP function is enabled, theYamaha wireless AP connected to this unit is automatically monitored byLLDP.

  - The input range is 1 - 60.

  - This item will only be displayed when Ping-based communication monitoring is selected for the "Monitoring type" item.

- Number of failures before detecting unavailable device

  - Specifies the number of times that the ping response must fail before determining that the monitored device is unavailable.

  - The input range is 1 - 100.

  - This item will only be displayed when Ping-based communication monitoring is selected for the "Monitoring type" item.

- Port

  - Specifies the port for frame monitoring.

  - The input format is portX.YY.

  - This item will only be displayed when Frame reception volume monitoring or LLDP reception interval monitoring is selected for the "Monitoring type" item.

- Monitor start band

  - Specifies the bandwidth at which frame reception volume monitoring will start.

  - The input range is 1 - 1000000000.

  - This item will only be displayed when Frame reception volume monitoring is selected for the "Monitoring type" item.

- Unavailable device detection band

  - Specifies the band value for determining that the monitored device is unavailable.

  - The input range is 0 - 999999999.

  - The value specified for this item must be less than the value used for "Monitor start band".

  - This item will only be displayed when Frame reception volume monitoring is selected for the "Monitoring type" item.

- Operation when detecting change in status

  - Terminal reboot due to temporary stop of PoE power supply

    - The PoE power supply for the target port will be temporarily stopped only when the device is detected to be unavailable.

      - Target port

        - Specifies the port for which the PoE power supply will be stopped.

        - The input format is portX.YY.

        - The input range is 1 - 60.

  - SNMP trap transmission

    - When a change of status is detected, a trap is notified to the SNMP manager.

  - Mail notification

    - An e-mail is sent when a change of status is detected.

    - The e-mail server, destination and so on must be configured in order to send e-mail.

### 4. Conditions for determining monitored device status

This explains the conditions for when the monitored device status changes.

- Monitoring with ping

  - If a ping packet transmitted by this unit does not return within the set time waiting for reply, this is counted as one failure, The status is determined by how many failures occur.

  - The conditions for change in status are shown below.

    - IDLE status

      - Initial status determination has not been completed after setting the monitored device.

    - UP status

      - Ping transmission has not failed continuously for the Number of failures before detecting unavailable device that was set.

    - DOWN status

      - Ping transmission fails continuously for the Number of failures before detecting unavailable device that was set.

- Monitoring according to frame reception volume

  - Measures the frame reception volume for the monitoring target and determines the status.

  - The conditions for change in status are shown below.

    - IDLE status

      - After the monitored device is configured, the frame reception volume for the monitored target port has not once exceeded the monitor start band that was set.

    - UP status

      - After the frame reception volume for the monitored target port exceeded the monitor start band that was set, it did not fall below the unavailable device detection band.

      - The frame reception volume for the monitored target port rose above the unavailable device detection band in DOWN status.

    - DOWN status

      - The frame reception volume for the monitored target port fell below the unavailable device detection band in UP status.

- Monitoring with LLDP

  - Status is determined by the LLDP frame reception status at the monitored target port.

  - The conditions for change in status are shown below.

    - IDLE status

      - After the monitored device is configured, no LLDP frames have been received at the monitored target port.

    - UP status

      - The next LLDP frame was able to be received at the monitored target port, within the TTL of the previously accepted LLDP frame.

      - An LLDP frame could be received in DOWN status at the monitored target port.

    - DOWN status

      - The next LLDP frame could not be received at the monitored target port, within the TTL of the previously accepted LLDP frame.
