Objective
Event Monitors are mainly used to monitor the device in a timely manner to give notifications to the technicians if there are any problems with the device performance. Testing in a network is done mainly to check the performance of the network. There are various tests which are available based on the monitors which are present in the device.
The DHCP Service needs to be monitored to ensure that it is active and that it assigns addresses to all the devices in the network. When this monitor is added to a device other than an OnPlus Network Agent, it is then authorized as a DHCP server for the network. This article explains the steps of how to monitor Network DHCP Service Availability on the ON100. This configuration is applicable for all the devices connected to the OnPlus like switches, access points, and so on.
Applicable Devices
• ON100
Software Version
• v7.6.2.038
Monitor Network DHCP Service Availability
Step 1. Log in to the Cisco OnPlus Portal, click the desired customer, and choose Dashboard.
Step 2. Move the mouse over ON100 device from the Network Topology view and click the Device Information icon. The Settings page opens.
Step 3. Click the Monitors tab. For each monitor, three icons are available. The first icon gives information about the particular monitor, the second icon is used test the monitor, and the third icon is used to indicate whether the monitor is enabled or not. Make sure the monitor is enabled before you any testing is done. Please refer to the article Enable or Disable a Device Monitor or All Monitors on OnPlus 100 for more information on how to enable a monitor.
Note: For the devices other than OnPlus Network Agent and devices which provide WAN port to connect to the Internet, this tab is blank when accessed first because event monitors are not added yet. In case of OnPlus, when OnPlus Network Agent is activated for a customer, the event monitors such as WAN Network Performance, CPU Load, Duplicate IP, DHCP Server, DNS Service, and Memory are enabled and created by default. Default Monitors in OnPlus Network Agent cannot be deleted but can be disabled, and the severity levels and other settings can be edited for these monitors.
Step 4. Click the DHCP Service monitor. The DHCP Service monitor has a latency parameter which can be edited.
Step 5. Enter the latency critical value in the Latency Critical field. It is a delay from the time of the start of packet transmission at the sender to the time of the end of packet reception at the receiver. Critical values are used to generate an event if there is no DHCP server response to a DHCP REQUEST packet in a specified amount of time.
Step 6. Click Test Monitor to test the DHCP Service Availability. A new page opens.
Step 7. (Optional) Check Generate an event to allow a real event to be created that reflects the result from the test. If the generated event has a delivery rule associated to it then the event will be created and delivered to the user in accordance to that rule.
Step 8. Click Run in the Run Test field to run the test. The results are shown.
Step 9. (Optional) Click the Back icon to return to the previous page to make any desired changes.
Step 10. Click OK to close the window.
