Monitoring the Network Running Status in Topologies

Monitoring the Network Running Status in Topologies

eSight displays the network running status in different colors in the physical topology. This is the most frequently-used network monitoring approach for a majority of users.

In the eSight system, the color, running status, and judgment standard and rectification method for abnormal status vary according to the topology object type. Table 7-8 provides the mapping between running status and icon colors for subnets and devices.

Running status of a subnet (physical subnet or IP subnet) reflects the running status of devices in the subnet. Table 7-8 provides the mapping between running status and icon colors for subnets.

The icon color of a subnet is the icon color of the device whose running status is the worst. For example:

  • A subnet is in offline state (the icon color is gray ) when devices in the subnet are in the following states:
    • Offline (the icon color is gray )
    • Critical alarm (the icon color is red )
    • Unknown alarm (the icon color is blue )
  • A subnet is in critical alarm state (the icon color is red ) when devices in the subnet are in the following states:
    • Critical alarm (the icon color is red )
    • Warning (the icon color is sky blue ).

When a device in the subnet is faulty, the subnet is faulty. The fault of the subnet is rectified when the device fault is rectified.

Device

  • In a topology, the icon color of a device reflects the running status of the device. Table 7-8 provides the mapping between running status and icon colors for devices.

    When the running status of a device is abnormal, perform related operations based on the following rules:

    1. If the device icon is sky blue, yellow, orange, or red, handle the alarm as prompted.
    2. If the device icon is gray, perform further analysis according to Table 7-9.
Table 7-9 Possible causes and solutions for the offline state

Possible Cause

Solution

The device is powered off.

Power on the device.

The IP address of the device is changed.

  1. Delete the device.
  2. Add the device to eSight again.
  • Users can move the mouse cursor to a device in the topology to view details, such as the device name and IP address.
NOTE:

If a device supports the display of performance data in the topology, create a performance collection task of the device in advance, so that collected data can be displayed.

Link

In a topology, the icon color of a link reflects the running status of the link. Table 7-8 provides the mapping between running status and icon colors for links.

The running status of a link is determined by the status (up or down) of the ports at the two ends of the link. Table 7-10 provides the mapping among link running status, link icon colors, and port status.

When the running status of a link is abnormal, perform related operations based on the following rules:

  1. If the link icon is orange or red, change the status of the ports at the two ends of the link. That is, set Admin Status (indicating the management status) and Oper Status (indicating the operating status) to up.
    • Admin status:
      NOTE:

      The admin status is applicable only to switches.

      1. Right-click a device connected through a link port and choose Device Information > Interface from the shortcut menu.
      2. On the Interface Manager page, click in the operation column.
      3. Change Admin Status to up and click OK.
    • Operating status:

      To set Oper Status to up, configure internal loopback for device ports or directly connect a network cable to the device.

  2. If the link color is gray, at least one of the two devices connected by the link is offline. To rectify the fault, bring the offline device online. For details, see Table 7-9.
