hi all,
in attachment the scheme.
vlan wi-fi 18 & 19
vlan mgt 20
on controller:
network profile id 18, 19, 20;
vlan id 18,19,20 tagged on port 4;
network access x.x.20.x with id vlan 20
n°2 SSID mapped on vlan 18 & 19
on switch:
port 20 tagged (18,19,20) and connect on msm-720
port 19 tagged (18,19,20) and connect on access-point 410
int vlan 18 ip add x.x.x.x /24
ip helper-address ip dhcp
int vlan 19 ip add x.x.x.x /24
ip helper-address ip dhcp
int vlan 20 ip add x.x.x.x /24
on dhcp server
n° 2 sessions dhcp for subnet 18 and 19
my problem is that the dhcp server doesn't release the ip address with right subnet, x.x.18.x for vlan 18 and x.x.19.x for vlan 19.
any idea!
