device to send a server unreachable trap message and disable portal authentication to permit
unauthenticated portal users if two consecutive probes fail.
[Firewall] 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.
[Firewall] 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.
408BVerifying the configuration
Use the following command to view information about the portal server.
<Firewall> display portal server newpt
Portal server:
1)newpt:
IP : 192.168.0.111
Port : 50100
Key : ******
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.

Troubleshooting portal
221BInconsistent keys on the access device and the portal server
409BSymptom
When a user is forced to access the portal server, the portal server displays a blank webpage, rather
than the portal authentication page or an error message.
410BAnalysis
The keys on the access device and those on the portal server are not configured consistently, causing
CHAP message exchange failure. As a result, the portal server does not display the authentication page.
