Setting The Maximum Number Of Portal Users - H3C SR8800-F Configuration Manual

Restrictions and guidelines for configuring an authentication source subnet
When you configure a portal authentication source subnet, follow these restrictions and guidelines:
•
Authentication source subnets apply only to cross-subnet portal authentication.
•
In direct or re-DHCP portal authentication mode, a portal user and its access interface
(portal-enabled) are on the same subnet. It is not necessary to specify the subnet as the
authentication source subnet. If the specified authentication source subnet is different from the
access subnet of the users, the users will fail the portal authentication.
In direct mode, the access device regards the authentication source subnet as any source
IP address.
In re-DHCP mode, the access device regards the authentication source subnet on an
interface as the subnet to which the private IP address of the interface belongs.
•
You can configure multiple authentication source subnets. If the source subnets overlap, the
subnet with the largest address scope (with the smallest mask or prefix) takes effect.
Configuring an IPv4 portal authentication source subnet
Step
1. Enter system view.
2. Enter interface view.
3. Configure an IPv4 portal
authentication source
subnet.
Configuring an IPv6 portal authentication source subnet
Step
1. Enter system view.
2. Enter interface view.
3. Configure an IPv6 portal
authentication source
subnet.

Setting the maximum number of portal users

Perform this task to control the total number of portal users in the system, and the maximum number
of IPv4 or IPv6 portal users on an interface.
Restrictions and guidelines for setting the maximum number of portal users
Make sure the maximum combined number of IPv4 and IPv6 portal users specified on all interfaces
does not exceed the system-allowed maximum number. Otherwise, the exceeding number of portal
users will not be able to log in to the device.
Setting the global maximum number of portal users
If you set the global maximum number smaller than the number of current online portal users on the
device, this configuration still takes effect. The online users are not affected but the system forbids
new portal users to log in.
