Example for Viewing Networking and Monitoring Network Operating Status In the Topology View

Example for Viewing Networking and Monitoring Network Operating Status In the Topology View

This example illustrates how to view the architecture of an enterprise campus network and monitor the network status in the topology view during routine maintenance.

Applicable Products and Versions

V300R002C00 or later versions

Networking Requirements

A company's O&M engineer Jack is responsible for monitoring the campus network to ensure normal service operation. The campus network consists of the headquarters and three branches a (R&D Dept), b (Sales Dept) and c (Finance Dept).

Jack wants to view the campus network architecture and monitor alarms and interface traffic on core devices to ensure normal network operation.

Figure 7-2 Topology of the campus network

Requirement Analysis

Jack's main requirements are as follows:

  • View the network architecture to understand the campus networking.
  • View status and interface traffic on core devices to determine the network health status.

It is recommended that Jack monitor the network status in the topology view.

Prerequisites

Devices have been added to eSight. For details, see Adding Resources.

Procedure

  1. Choose Topology > Topology Management from the main menu.

  2. View alarms in the alarm panel. If alarms exist, you are advised to clear the alarms first.

    1. Click the alarm icon to display the Current Alarms page.
    2. Find the alarm on the Current Alarms page. Click next to the alarm to quickly switch to the physical topology.

    3. On the Physical Topology page, check the device status and the position of the device on the network. If the device color is red in the topology view, the alarm exists. Jack needs to release a warning to other management personnel of the device to inform that the device is faulty and the fault is being rectified.
    4. Rectify the fault. If it is a simple and common alarm, rectify the fault based on maintenance experience. If it is a complex alarm, rectify the fault by referring to Handling Experience on the Current Alarms page.

    5. Verify alarms. On the alarm board, check whether the alarm is cleared.

    6. Acknowledge the alarm. After acknowledging an alarm, choose Choose Fault > Historical Alarms from the main menu to add the cleared alarm to the historical alarm library.

  3. View the campus network topology.

  4. View performance indicators of core devices.

    1. Move the pointer over a device icon to view the average CPU usage and memory usage of the device.

      NOTE:

      If the device's CPU usage and memory usage remain high, network adjustment or device capacity expansion is required.

    2. Move the pointer over a link to view the interface receive rate and inbound bandwidth usage.

    NOTE:
    • If the interface traffic volume remains high, check whether it is caused by increasing service volume.
    • If the bandwidth usage remains high, network adjustment or device capacity expansion is required.
    • You can right-click in the physical topology and set the link display mode such as the link name and label.

Summary and Suggestions

  • During network maintenance, the physical topology is commonly used for network monitoring.
  • eSight provides various menus after you right-click in the physical topology. You can complete routine maintenance operations in the physical topology view.
