H3C S7500E Series Ethernet Switches Chapter 1 Portal Configuration
1-21
When the user uses the disconnect attribute on the client to log out, the portal server
actively sends a REQ_LOGOUT message to the access device. The source port is
50100 and the destination port of the ACK_LOGOUT message from the access device
is the source port of the REQ_LOGOUT message so that the portal server can receive
the ACK_LOGOUT message correctly, no matter whether the listening port is
configured on the access device. Therefore, the user can log out the portal server.
III. Solution
Use the display portal server command to display the listening port of the portal
server on the access device and use the portal server command in the system view to
modify it to ensure that it is the actual listening port of the portal server.
