Usage guidelines
When the Rule ARP or ND entry feature is enabled for portal clients, ARP or ND entries for portal
clients are Rule entries after the clients come online. The Rule ARP or ND entries will not age out
and will be deleted immediately after the portal clients go offline.
If portal clients go offline and then try to come online before the ARP or ND entries are relearned for
them, the clients will fail the authentication. In this case, disable this feature so that ARP or ND
entries are dynamic entries after the clients come online. The dynamic ARP or ND entries are
deleted only when they age out.
Enabling or disabling of this feature does not affect existing Rule/dynamic ARP or ND entries for
portal users.

Usage guidelines
Portal roaming applies only to portal users that log in from VLAN interfaces.
This command cannot be executed when online users or preauthentication portal users are present
on the device.
If portal roaming is enabled, an online portal user can access network resources from any Layer 2
port in its local VLAN. If portal roaming is disabled, the portal user can access network resources
only from the Layer 2 port on which it passes authentication.
For portal roaming to take effect, you must disable the Rule ARP or ND entry feature by using the
undo portal refresh
{
arp
|
nd
}
enable
command.
Examples
# Enable portal roaming.
<Sysname> system-view
[Sysname] portal roaming enable
