Changing Frequencies - ePMP -cnMaestro

Problem Description:

There is a requirement to change the Center and Alternative Frequencies for an ePMP AP managed by cnMaestro.

How to fix:

STEP 1:

In the cnMaestro Portal navigate to the Monitor & Manage Tab, then to the ePMP AP you wish to make changes to.

STEP 2:

Click on the Configuration Tab and click on the link "View Device Configuration" 

A new window will pop up showing the device configurations, click on "Save as Template"

Name the Template and Save

STEP 3:

Navigate to the Configuration>Template Tab

STEP 4:

Select the Template and Click on the Pencil Icon to begin editing

STEP 5:

Locate the Strings that detail the Frequency Fields - In our example we have the following 

"centerFrequency". "5550"

"dfsAlternative1CentreFrequency". "5490"

"dfsAlternative2CentreFrequency". "5495"

STEP 6:

Edit the Strings to create variables that can be used when applying the Template to the AP.

We do this by using the following method - replacing the "Frequency" with "${VARIABLE}"

Save the Template

STEP 7:

Navigate back to Monitor and Manage and select the ePMP AP again. Scroll down to Device Configuration and Select the Template we have created, in our example "AP Template Frequency"

STEP 8:

Input the desired Centre and Alternative Frequencies and click Apply Configuration

Note: This Template can only be used on this AP as the Template contains other configurations specific fo this AP, for example IP Address, Device Name, etc.

When you apply the configuration this will result in a reboot of the ePMP AP, if there are any SMs connected to this AP these sessions will be dropped.

For an example of a Template used to change the Frequencies only on and ePMP AP you can use the below,

{
"template_props": {
"templateName": "",
"templateDescription": "",
"device_type": "",
"version": "4.6.0.1"
},
"device_props": {
"centerFrequency": "${Center Frequency}",
"dataVLANEnable": "0",
"mcastVLANEnable": "0",
"dfsAlternative1Bandwidth": "2",
"dfsAlternative1CenterFrequency": "${Alt2Frequency}",
"dfsAlternative2Bandwidth": "2",
"dfsAlternative2CenterFrequency": "${Alt3Frequency}"
}
}
