Usage guidelines
If you do not specify the server server-name argument, this command clears packet statistics for all
portal authentication servers.
Examples

<Sysname> reset portal packet statistics server pts

server-detect (portal authentication server view)
Use server-detect to enable portal authentication server detection. After server detection is enabled
for a portal authentication server, the device periodically detects portal packets from the server to
identify its reachability status.
Use undo server-detect to disable portal authentication server detection.
Syntax
server-detect [ timeout timeout ] log
undo server-detect
Default
Portal authentication server detection is disabled.
Views
Portal authentication server view
Predefined user roles
network-admin
Parameters
timeout timeout: Specifies the detection timeout in the range of 10 to 3600 seconds. The default is
60 seconds.
log: Configures the device to send a log message after it detects reachability status change of the
portal authentication server. The log message contains the name, the original state, and the current
state of the portal authentication server.
Usage guidelines
The portal authentication server detection feature takes effect only when the device has a
portal-enabled interface.
To test server reachability by detecting heartbeat packets, you must enable the server heartbeat
feature on the portal authentication server. Only the IMC portal authentication server supports
sending heartbeat packets.
The detection timeout configured on the device must be greater than the server heartbeat interval
configured on the portal authentication server.
If the device receives portal packets from the portal authentication server before the detection
timeout expires and verifies the correctness of the packets, the device considers the portal
authentication server is reachable. Otherwise, the device considers the portal authentication server
is unreachable.
