Hello,
Run the display network status all command to view the tasks that occupy all the TCP/UDP port numbers.
Example
<Huawei> display network status all
Proto Task/SockId Local Addr&Port Foreign Addr&Port State
TCP VTYD/1 0.0.0.0:23 0.0.0.0:0 Listening
TCP HTTP/2 0.0.0.0:80 0.0.0.0:0 Listening
TCP HTTP/1 0.0.0.0:443 0.0.0.0:0 Listening
TCP VTYD/59 192.168.50.166:23 10.135.19.141:60445 Established
TCP6 VTYD/2 ::->23 ::->0 Listening
UDP AGNT/1 0.0.0.0:161 0.0.0.0:0
UDP SLAG/1 0.0.0.0:1025 0.0.0.0:0
UDP RDS /1 0.0.0.0:1812 0.0.0.0:0
UDP6 AGT6/1 ::->161 ::->0
UDP6 RDS /2 ::->1812 ::->0
By default, the device uses port 2000 to listen on Portal protocol packets. You can use the web-auth-server listening-port command to the web port number.
Example
# Set the number of the port through which a device listens on Portal protocol packets to 3000.
<Huawei> system-view
[Huawei] web-auth-server listening-port 3000
I hope this helps.
