heartbeat packets or authentication packets (such as login requests and logout requests), it

•
trap
: Specifies the action as sending a trap message. When the status (reachable/unreachable)
of a portal server changes, the access device sends a trap message to the network
management server (NMS). Trap message contains the portal server name and the current
state of the portal server.
interval
interval
: Interval at which probe attempts are made. The
interval
argument ranges from 20
to 600 and defaults to 20, in seconds.
retry
retries
: Maximum number of probe attempts. The
retries
argument ranges from 1 to 5 and
defaults to 3. If the number of consecutive, failed probes reaches this value, the access device
considers that the portal server is unreachable.
Usage guidelines
You can specify one or more detection methods and the actions to be taken.
If both detection methods are specified, a portal server is regarded as unreachable as long as one
detection method fails, and an unreachable portal server is regarded as recovered only when both
detection methods succeed.
If multiple actions are specified, the system executes all the specified actions when the status of a
portal server changes.
Deleting a portal server on the device will delete the detection function for the portal server.
If you configure the detection function for a portal server for multiple times, the last configuration
takes effect. If you do not specify an optional parameter, the default setting of the parameter is used.
The portal server detection function takes effect only when the portal server is referenced on an
interface.
Authentication-related packets from a portal server, such as logon requests and logoff requests,
have the same effect as the portal heartbeat packets for the portal server detection function.

Examples
# Configure the device to detect portal server
pts
:
•
Specifying both the HTTP probe and portal heartbeat probe methods
•
Setting the probe interval to 600 seconds
•
Specifying the device to send a server unreachable trap message, send a log message and
disable portal authentication to permit unauthenticated portal users, if two consecutive probes
fail.

portal server user-sync
Use
portal server user-sync
to configure portal user information synchronization with a specific
portal server. When this function is configured, the device periodically checks and responds to the
user synchronization packet received from the specified portal server, so as to keep the consistency
of the online user information on the device and the portal server.
Use
undo portal server user-sync
to cancel the portal user information synchronization
configuration with the specified portal server.
