Configuring Portal Detection Functions; Configuring Online Layer 2 Portal User Detection; Configuring The Portal Server Detection Function - HP 3600 v2 Series Configuration Manual

Follow these guidelines to specify an auto redirection URL for authenticated portal users:
• To use this feature for remote Layer 3 portal authentication, the portal server must be the IMC portal
server that supports the page auto-redirection function.
The wait-time period option is effective to only local portal authentication.
•
When no auto redirection URL is specified for authenticated portal users, an authenticated user is
•
usually redirected to the URL the user typed in the address bar before portal authentication.
However, with local portal authentication, if the URL a user typed in the address bar before portal
authentication is more than 255 characters, the user cannot be redirected to the page of the URL
after passing portal authentication.
To specify an auto redirection URL for authenticated portal users:
Step
1. Enter system view.
2. Specify an auto redirection
URL for authenticated portal
users.

Configuring portal detection functions

Configuring online Layer 2 portal user detection

Only Layer 2 portal authentication supports this feature.
After a Layer 2 portal user gets online, the device starts a detection timer for the user, and checks whether
the user's MAC address entry has been aged out or the user's MAC address entry has been matched (a
match means a packet has been received from the user) at the interval. If the device finds no MAC
address entry for the user or receives no packets from the user during two successive detection intervals,
the device considers that the user has gone offline and clears the authentication information of the user.
To set the Layer 2 portal user detection interval:
Step
1. Enter system view.
2. Enter interface view.
3. Set the Layer 2 portal user
detection interval.

Configuring the portal server detection function

Only Layer 3 portal authentication supports this feature.
During portal authentication, if the communication between the access device and portal server is
broken, new portal users are not able to log on and the online portal users are not able to log off normally.
