My knowledge on WLAN is very limited so my question may sound very basic.
Layer 3 uplinks between collapsed core/distribution and access layer switches on each floor. Hence AP on each floor is on a different VLAN/subnet.
When a Client migrates between an AP, it retains the SSID and it also Retains its OLD DHCP address – it does not request a new one. Therefore, when client moves from one floor to another it keeps the IP from the previous floor.
Is it normal behavior that the client will maintain the same IP address when moving between floors (where the AP's are on different IP subnets) to maintian IP connectivity?
