DNAC not allowing < character in WLAN PSK, even though 9800 WLC does?

[Will Pettit]

Hi, We have an issue in that DNAC will not all a < character in a wifi PSK.
We've just moved from WISM2s to 9800 WLCs and they both allow the < character. 
Every time I re-provision the WLC for any changes, it will overwrite the PSK on the 9800. 
Changing the PSK on the devices will mean sending them all back to the manufacturer, which we'd like to avoid. Is this a bug?

The documentation suggests that ASCII characters 32-127 are allowed.

DNAC version is 2.3.5.3-70194

Thanks, Will

I would consider this a bug, you should open a TAC case to have this resolved.

In the meantime I believe you should be able to resolve this by overwriting the PSK in a template. Something like this:

! @start-ignore-compliance
wlan {your wlan}
 security wpa psk set-key ascii 0 {yourpassword}
! @end-ignore-compliance
