Adding 160 Mhz Channels to Existing 4625 Subscribers

All of the Subscriber Modules (4625) on our systems are using 80 Mhz channels. All of them are programmed to use either 80 Mhz or 40 Mhz channels. Most are not programmed with the capability of using 160 Mhz channels. I want to add all 160 Mhz channels to them.

We have about 400 SMs on about 17 4600 APs. To add the addition channels to each SM one at a time is obviously very time consuming.

If I create a template (which I have not ever used), can I just put in that template the information to add the addition channels to the SMs or do I need to put in all of the configuration for the SM in that template? There’s nothing else in the configuration of each SM that I want changed - ONLY adding the 160 Mhz channels.

Is this possible? If so, since I’m not familar (yet) with using JSON, what would be the proper information to put in a template to achieve what I want?

Hello @John_Rayfield ,

The parameter below controls the scan channel bandwidth:

wirelessInterfaceScanFrequencyBandwidth OBJECT-TYPE
	SYNTAX	   Integer32 (1..127)
	MAX-ACCESS read-write
	STATUS	   current
	DESCRIPTION
		"Frequency Bandwidth as bitmask, fields are:
			1 - 20Mhz,
			2 - 40Mhz,
			4 - 10Mhz,
			8 - 5Mhz,
			16 - 80Mhz (802.11ac/ax/be)
			32 - 160Mhz (802.11ax/be)
			64 - 320Mhz (Only for 802.11be)
		Device Allocation: SM"
	DEFVAL	{ 1 }
	::= { wirelessInterface 32 }

If you would like to enable scanning for both 80 MHz and 160 MHz frequencies, the template configuration should be defined as follows:

{
	"device_props": {
		"wirelessInterfaceScanFrequencyBandwidth":	"48"
		
	}
}

For additional guidance on creating templates in cnMaestro for ePMP radios, please refer to the following resource:

Please let me know if you have any further questions.

So if he wants to keep 40 & 80, and to add 160mhz, then the parameters value would be “50” (2 + 16 + 32)

Do I have to use the entire configuration, or can I just use the portion to change/add the frequency bandwidth? Will a ‘partial’ template only over-write that portion of the template, or does the entire configuration get replaced?

Yes, exactly. That’s exactly the concept of these templates. If you want to change one setting, and leave everything else the same, then you basically just template that one tiny chunk.

Of course, as with everything, You want to test it first on some SM that’s quick and easy to get to. :ok_hand:
