Offline Diagnosis and Video Quality Diagnosis of an IPC

Offline Diagnosis and Video Quality Diagnosis of an IPC

Fault diagnosis of an IPC includes offline diagnosis and video quality diagnosis. The possible causes of a fault can be analyzed through offline diagnosis and video quality diagnosis and the fault can be diagnosed based on the Enhanced Media Delivery Index (EMDI), helping O&M personnel quickly demarcate and locate the fault.

Prerequisites

  • Video surveillance devices and IPCs have been added to eSight.
  • The Automatic Terminal Discovery function has been enabled on the Discovery Rule page of eSight. If the function is not enabled, E2E diagnosis is unavailable.
  • LLDP has been enabled for the network devices. Network devices with LLDP disabled cannot be displayed in the topology and may lead to inaccurate restoration of the topology of other network devices.
  • Egress devices must be configured in advance if the intermediate network has unmanageable devices or has layer-3 forwarding devices crossing two layers. For details, see Setting Egress Devices.
  • For the CloudVCN, you need to set the external service IP address. For details, see How Do I Set the External Service IP Address.

Diagnosis Scope

Currently, only IPCs, network devices, and VCNs support offline diagnosis and video quality diagnosis. Alarm information is displayed for IPCs and VCNs. For network devices, the CPU usage, memory usage, bandwidth usage, packet loss rate, optical power, and MOS are displayed.

Restrictions

  • NAT translation is not allowed between IPCs and VCNs.
  • The IPC must be online before, and topology restoration has been periodically or manually triggered for the IPC when it is online. Otherwise, the IPC cannot be diagnosed when it goes offline.
  • Multiple intermediate links may be displayed at the same time. This depends on the aging time and restoration time of the MAC address table and ARP table. For example, if active/standby switchover is performed in the active-standby scenario and the ARP table or MAC address table is not aged on the active node, the topology displays both the active and standby nodes.
  • The topology cannot be restored for non-Huawei network devices.
  • Diagnosis is not supported for PON devices and microwave devices.
  • If the access device of an IPC or VCN is a non-Huawei device or a non-managed device, the device cannot be sensed during E2E diagnosis.
    • If the upper-level device is a layer-2 forwarding device, the upper-level device is displayed in the topology restoration result as the access device of the IPC or VCN.
    • If the upper-level device is a layer-3 forwarding device, topology restoration is not supported.
  • A maximum of 20 IPCs can be diagnosed at the same time. For KPI diagnosis, a maximum of five pages can be opened at the same time. If more than five pages are opened, the KPI data and trend chart are not displayed.
  • For all-in-one servers, the VCN/CLOUDVCN requires that the IPC and VCN gateway can be managed. Otherwise, the E2E diagnosis function is unavailable.
  • After offline diagnosis or quality diagnosis starts, performance indicator data and trend chart in only one hour are displayed. One hour later, the task for collecting device performance data is closed and data is not displayed. You can click offline diagnosis or quality diagnosis to trigger data collection again. Then, the collected performance indicator data is displayed.
  • The number of links on the topology of an IPC cannot exceed 20. Otherwise, the topology restoration will fail.

Procedure

  1. Choose Resource > Video Surveillance from the main menu.
  2. In the navigation tree on the left, choose Video Surveillance > Fault Diagnosis > Diagnosis.
  3. In the search box in the middle of the page, enter the IPC name, IP address, or region for search.

    NOTE:
    • You can also choose Video Surveillance > Resource Management > Peripheral Unit or Video Surveillance > Resource Management > Camera in the navigation tree, and click in the Operation column for diagnosis.
    • Alternatively, you can choose Monitoring Management > Quality Map and perform diagnosis on the GIS map. For details, see 3.c.

  4. In the Camera Information area, view information about the IPC, including the basic information, alarm information, and trend chart. The basic information includes the IP address, region, VCN, and location. The alarm information needs to be viewed only when there is a fault. The trend chart displays the IPC online duration trend and IPC intact duration trend in the latest seven days.

  5. In the Camera Network Topo area, view the restored IPC network topology.

    Description

    Diagnosis type

    • Offline diagnosis: eSight performs offline diagnosis for offline IPCs by default.
    • Video quality diagnosis: eSight performs video quality diagnosis for online IPCs by default.
    • If the IPC information changes, you can click or to diagnose the IPC again.

    Indicator

    • You can select the indicator to be monitored from the Switch drop-down list box. The indicators include the bandwidth usage, packet loss rate, optical power, and MOS. Both the collection period and update period are 10 seconds.
    • The arrows indicate the incoming and outgoing directions.

    Legend

    • When you move the mouse pointer to , the legend describing performance indicator data is displayed, as shown in the following figure.

    Topology

    • In the topology, a faulty device is displayed in red, a device that is suspected to be faulty is displayed in yellow, and a normal device is displayed in light blue. When a topology is restored, all devices are displayed in light blue because they are considered as normal by default.
    • The CPU usage and memory usage of a device are always displayed.
    • The site, tunnel, and center are described as follows:
      • Site: devices at a site, including the PUs, directly-connected access devices, and power supplies.
      • Tunnel: network devices between IPCs and VCNs.
      • Center: VCN and access devices that are directly connected to the VCN.

      An example is as follows.

    • You can move the mouse pointer to an IPC or NE to view its basic information, or move the mouse pointer to a link to view the complete KPIs and details, as shown in the following figure.

    NOTE:

    If a link contains PON devices, the link supports only offline diagnosis and displays only PON devices, IPCs, and VCNs.

  6. Check the diagnosis result.

    • In the Diagnosis Overview area, view the diagnosis result, as shown in the following figure.

    NOTE:

    EMDI is a network quality monitoring and fault demarcation solution designed for video and audio services. EMDI can monitor specified service packets on each node of an IP network in real time, and quickly locate the faulty network segment based on the monitoring results of multiple nodes. Before performing EMDI diagnosis on a link, you need to deploy EMDI on the network node.

    • You can click an NE in the IVS Network Topo area to view the detailed status of the NE, as shown in the following figure.

    NOTE:
    • If an NE is suspected to be faulty or indeed faulty, the details tab page of the NE displays the fault summary and data trend.
    • If the fault occurs because the CPU or memory usage of the IPC is high, you are advised to restart the IPC to rectify the fault. The procedure is as follows:
      1. Click Remote Restart in the IVS Network Topo area.
      2. Click Yes in the dialog box that is displayed.
