Ruckus ICX7150 C12P Dynamic PoE Power Unavailable

I have several C12Ps, all running 9.0.10j:

The admin guide indicates that dynamic PoE power is configurable:
https://docs.commscope.com/bundle/fastiron-09010-managementguide/page/GUID-CAA036D6-595D-4481-A140-2...

"If you want to configure Static PM to a specific port after enabling Dynamic PM on all ports, configure the required ports with priority 1. Unless the Power Supply Unit (PSU) is removed, Priority 1 ports will never lose power. The following is an example of configuring a specific port to Static PM after Dynamic PM has been configured."

device# configure terminal
device(config)#inline power allocation dynamic all
device(config)# interface ethernet 1/1/15
device(config-if-e1000-1/1/15)#inline power priority 1

However, the CLI does not recognize this command:
SSH@adjunct.madison911.net(config)#inline power allocation dynamic all
Invalid input ->allocation dynamic all
Type ? for a list
Node doesn't exist
SSH@blah.net(config)#

I need this feature in the switch, as I cannot add additional access points to my homes' switches.  Despite each AP using at most 11 watts at peak, the switch preallocates 30watts from the budget, limiting the deployment to 4 APs at most.  This is well known of course in the 8.x line of code, which is why I moved to 9.0.10j as the release notes and admin guide indicated (as above) that dynamic power was available.

Hi @chadm 

Thank you for the response.

However, you can refer to the below links which can help you adjusting PoE power limit.

Let me know if you have any queries.

Thank you again for your patience and understanding.

I appreciate that approach, and have already tried it.  However, this power limit is communicated to the devices, which influences their performance (e.g. an AP goes into lower power mode if it does not negotiate full class 4 power at boot, despite using less than 11 watts total nominally under full load). 

For those looking for a solution, research mid-span multiport Gige PoE injectors.  They exist and are far more cost effective than replacing a switch that supports dynamic power allocation.  The disadvantages are having a second/middle box, and being unable to shut the ports/power down per ethernet port via the CLI/UI.
