Static IPs within multi-subnet/VLAN WLANS

[Joshpre]

Hi All,

Is it possible to have a static IP address with a WLAN that has multiple subnets/Vlans assigned.

Additionally is there a method for ensuring the device is always assigned back to the same VLAN after a long period of downtime.

WLC-9800 series
Code ver - 17.6.4

TIA

              - That is a conflicting idea because usually different subnets will use different IP ranges

                     The WLAN will usually have static vlan assigned  , (if using https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wlan-security/217043-configure-dynamic-vlan-assignment-with-c.html , then DHCP for assigning  client addresses is a must)

 Appendix : when configuring your controller it is always best to have a review of it's configuration when done :
                                  Use CLI show tech wireless ; have the output analyzed with :

Thanks Marce1000,

              - That is a conflicting idea because usually different subnets will use different IP ranges - I understand this, however the static IP is required by certain devices on our wireless network. in an ideal world we'd just say they're not supports.

>is there a method for ensuring the device is always assigned back to the same VLAN after a long period of downtime.

Thanks for your reply.
