Clients get Cato cloud DHCP leases on the wrong subnet range vlan

Looking for a solution to our wireless clients getting DHCP leases on the wrong subnet / range / vlan.  Some of our clients getting Cato cloud DHCP leases on the same subnet as the access points on trunk native VLAN.  VLAN is native VLAN on truk between access points and switches.

    Hi Csthomas,

    It sounds like the VLAN is being used or configured for multiple purposes, with multiple DHCP servers operating on the same segment. To ensure proper traffic flow and avoid conflicts, the VLAN segmentation design across the LAN and WLAN—specifically between the switch, AP, WLC, and Cato—should be reviewed.

    HI csthomas, 

    Usually we would check the DHCP configuration on the WLAN system and review the DHCP settings.
    Can we check which Wireless solution are you using?

    Cheers

    Correction to that.  The VLAN is the assigned VLAN on the access mode switch ports that the access points are plugged into.  Not natve vlan on a trunk.
