WLC 8510 v8.0.152.0 Expected outage for changing client's interface netmask

[Feds]

Hi all,

I need to expand a wireless VLAN's subnet from /22 to /20, interface on WLC is not statically referenced in any of the configured WLANs as "Interface/Interface Group(G)" since we use dot1x (via ISE) but it is referenced under one WLAN as "Multicast interface".

I was wondering if the "Changing the Interface parameters causes the WLANs to be temporarily disabled and thus may result in loss of connectivity for some clients" alert applies in this case. Should I expect all wireless clients (in this case they are all 8821 wireless IP Phones) to be disassociated from this WLAN when I change the netmask?

Even if not relevant with the main question, would these IP Phones also reboot as a result of the disassociation (if that's the case)?

Any comment will be appreciated.

Thank you.

Fed

Yes clinet will reassociated if you change in dynamic interface configuration.
