The tcp listen-mode any-ip command sets the TCP listening mode to any IP on a TWAMP server.
The tcp listen-mode assign-ip command sets the TCP listening mode to assigned IP on a TWAMP server.
By default, the TCP listening mode is assigned IP.
Usage Scenario
After TWAMP is enabled, you can configure a TCP listening mode for the TWAMP server to respond to TCP connections initiated by the TWAMP client. If the TCP listening mode is set to any IP, no listening address needs to be configured. If the TCP listening mode is set to assigned IP, you must specify a TCP listening address.
