Enabling portal roaming
About portal roaming
If portal roaming is enabled on a VLAN interface, an online portal user can access resources from any Layer 2 port in the VLAN without re-authentication.
If portal roaming is disabled, to access external network resources from a Layer 2 port different from the current access port in the VLAN, the user must do the following:
Logs out from the current port.
Re-authenticates on the new Layer 2 port.
Restrictions and guidelines
Portal roaming takes effect only on portal users logging in from VLAN interfaces. It does not take effect on portal users logging in from common Layer 3 interface.
You cannot enable portal roaming when online portal users or preauthentication portal users exist on the device.
