    Bandwidth Required for Monitoring AP

      Hi Experts,

       

      I am having one doubt regarding the bandwidth required for monitoring an AP in Entuity.

       

      1) Suppose if switch/router/firewall and it takes 2 Kbps of Bandwidth to monitor a switch/router/firewall in Entuity.

      2) Same way if we monitor a Wireless Controller and it takes 3 Kbps of Bandwidth for Monitoring one Wireless Controller then will the access points connected to that Wireless Controller will be monitored using the same bandwidth?

      3) Or the Bandwidth will different for different APs of same Wireless controller?

       

      OR

       

      Will the Wireless Controller and APs will use different bandwidth for them to be monitored in Entuity?

       

      Same is the question for Meraki Controller and devices as well.

       

      If anyone can help in understanding the same.

       

      Thanks!!!!

          Avinash,

           

          When Entuity monitors a wireless controller (other than Meraki), all of the information is obtained by polling the wireless controller. Entuity does not poll the access points as the information about the access points is stored on the controller.

           

          In order to manage Meraki WiFi deployments, you need to do the following:

          • Manage the Meraki CMP as an SNMP-managed device, configured as the "Wireless Controller" device type.

          In this case, there is no need to manage the individual wireless access points, because information about these will be polled and displayed in relation to the wireless controller device (just like any other wireless controller device).

          You can distribute direct SNMP polling of Meraki devices across multiple Entuity servers. The CMP should only be managed once, via its RESTful API, on any one of your Entuity servers.

            Hi Larry,

             

            Thanks for your inputs.

             

            I had few more queries regarding the same.

             

            So Shall I consider 1 device bandwidth no matter how many AP's are managed/connedted to that particular Controller.

             

            For Example: If I have 1 Wireless controller and the Controller has 400 APs connected to it then whatrever the bandwidth is required to monitor the Wireless controller only that much is used and no additional bandwidth will we required.

             

            Thanks!!!!

              Avinash,

               

              The traffic to/from the controller will be dependent upon the number of APs attached to the controller. Entuity does perform bulk SNMP GET operations to more efficiently utilize the bandwidth. If the number of attached APs does not change, then the bandwidth utilized should be fairly consistent. If you have a Windows server, you can monitor the bandwidth to/from the Entuity server to the wireless controller by monitoring the eyepoller process. Bring up the Windows Resource Monitor utility and select the Network tab. Locate the process named eyepoller.exe. This will display the traffic to the individual monitored devices and display the network bandwidth being consumed. In the screenshot below, the traffic to a device named stack3750 is displayed. If the device is monitored by its IP address, then the address is displayed.
