I'm setting up Cucumber hotpspot on Aruba AP 225. IN one of the steps it is asked to change the  change the format of the calledstationid.

From Cucumber..:

In recent firmwares, you need to change the format of the calledstationid, commonly known as mac address.

18:64:7x:cx:9x:1x (SSID Profile "cucumber") # auth-pkt-mac-format delimiter -  
18:64:7x:cx:9x:1x (SSID Profile "cucumber") # auth-pkt-mac-format upper-case delimiter - 
18:64:7x:cx:9x:1x # commit apply 
18:64:7x:cx:9x:1x # write mem
	

 In UI, iI'm not able to find this option.

We can configure “mac-authentication-delimiter” and “mac-authentication-upper-case” on both WEBUI and CLI.

But we can only configure “auth-pkt-mac-format { upper-case } { delimiter <delim> }” on CLI.

Can you please point out where this options would be on UI.

Model number: ARUBA AP225

my apology but i communicated that this option would not be in UI:

"can only configure “auth-pkt-mac-format { upper-case } { delimiter <delim> }” on CLI."
