The ospf flush-source-trace port command configures a UDP port number for OSPF flush LSA source tracing packets.
The undo ospf flush-source-trace port command restores the default UDP port number for OSPF flush LSA source tracing packets.
By default, the UDP port number of global OSPF flush LSA source tracing packets is 50122, and the UDP port number of Vlink OSPF flush LSA source tracing packets is 50123.
Usage Scenario
The OSPF flush LSA source tracing port receives and sends OSPF flush LSA source tracing packets, and the port is identified by a UDP port number.
If the UDP port number conflicts with that of an application, you can change the UDP port number of OSPF flush LSA source tracing packets using the ospf flush-source-trace port command. To change the UDP port number of Vlink OSPF flush LSA source tracing packets, run the ospf flush-source-trace vlink port command.
