[Router] portal server newpt ip 192.168.0.111 key simple portal port 50100 url
http://192.168.0.111:8080/portal
# Enable portal authentication on the interface connecting the host.
[Router] interface gigabitethernet 3/0/2
[Router–GigabitEthernet3/0/2] portal server newpt method direct
[Router–GigabitEthernet3/0/2] quit
4. Configure the portal server detection function:
# Configure the access device to detect portal server newpt, specifying the detection method as
portal heartbeat probe, setting the server probe interval to 40 seconds, and specifying the access
device to send a server unreachable trap message and disable portal authentication to permit
unauthenticated portal users if two consecutive probes fail.
[Router] portal server newpt server-detect method portal-heartbeat action trap
permit-all interval 40 retry 2
The product of interval and retry must be greater than or equal to the portal server heartbeat
interval, and HP recommends configuring the interval to be greater than the portal server
heartbeat interval configured on the portal server.
5. Configure portal user information synchronization:
# Configure the access device to synchronize portal user information with portal server newpt,
setting the synchronization probe interval to 600 seconds, and specifying the access device to log
off users if the users do not appear in the user synchronization packets sent from the server within
two consecutive probe intervals.
[Router] portal server newpt user-sync interval 600 retry 2
The product of interval and retry must be greater than or equal to the portal user heartbeat interval,
and HP recommends configuring the interval to be greater than the portal user heartbeat interval
configured on the portal server.
Verifying the configuration
Use the following command to view information about the portal server.
<Router> display portal server newpt
Portal server:
1)newpt:
IP : 192.168.0.111
Key : ******
Port : 50100
URL : http://192.168.0.111:8080/portal
Status : Up
The Up state of the portal server indicates that the portal server is reachable. If the access device detects
that the portal server is unreachable, you can see the portal server status is Down in the output, and the
access device generates a server unreachable trap "portal server newpt lost" and disables portal
authentication on the access interface, so the client can access the external network without
authentication.
Cross-subnet portal authentication across VPNs
Network requirements
As shown in Figure 74, Router A, as the PE device connecting the user side, needs to provide cross-subnet
portal authentication for hosts in VPN 1. The RADIUS server/portal server is in VPN 3.
