H3C MSR Series Command Reference

387
log: Enables the device to send a log message when it detects a 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.
The portal authentication server detection feature takes effect only when the portal authentication
server supports server heartbeat. Now only the IMC portal authentication server supports server
heartbeat.
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.
Examples
# Enable server detection for the portal authentication server pts:
• Set the detection timeout to 600 seconds.
• Configure the device to send a log message when it detects a reachability status change of the
portal authentication server.
<Sysname> system-view

Parameters
interval interval: Specifies a detection interval in the range of 1 to 1200 seconds. The default is 5
seconds.
retry retries: Specifies the maximum number of consecutive detection failures, in the range of 1 to
10. The default is 3. If the number of consecutive failed detections reaches this threshold, the device
considers the server as unreachable.
