1) PORT 1920:
By default, a http port 1920 is allocated during starting of the first ITM component. This port is used to serve service console request as well as the TEPS and SOAP server request. if this port is not available, a random port is allocated and used for http request.
The owner of the base HTTP port 1920 will redirect the calls to the random http port allocated by the other ITM components. The same can happen to the HTTPS port 3661.
Note that the allocated random http port is bound to 1920, so the http request is served using a random port as well as 1920
The random http and https ports allocated by the ITM components can be identified from the RAS1 log of the ITM component
(4FEDD526.0015-32B4:kdhslqm.c,349,"add_listener") listening: ip.tcp.http:59029
(4FEDD526.0027-32B4:kdhslqm.c,349,"add_listener") listening: ip.ssl.https:59031
(4FEDD526.0013-32B4:kdhslqm.c,349,"add_listener") listening: ip6.tcp.http:59028
(4FEDD526.0021-32B4:kdhslqm.c,349,"add_listener") listening: ip6.ssl.https:59030

2) PORT 3661:
by default, a https port 3661 is allocated for secure http request during starting of the first ITM component. This port is used to serve service console request as well as the TEPS and SOAP server request. if this port is not available, a random port is allocated and used for https request.
3) PORT 4096:
A basic services port is allocated which is based on ITM port allocation algorithm
(well-known port + count * 4096)
where the well-known port is the port number assigned to the monitoring server . The default port number assigned to monitoring server is 1918.
Let's say, if the well-known port assigned to monitoring server is 1918, the first started monitoring agent gets 1918+4096=6014, if the port 6014 is busy then 1918 + 2 * 4096 = 10110 port will be allocated to the monitoring agent and so on.. if the port 6014 is RESERVED, then the agent won't start and fail

4)PORT 15001:
In addition TEPS uses 15001 for its own purpose.
NOTE : all the above ports can be controlled using POOL parameter and the explanation of POOL parameter is not the scope of this technote

5) PORT 9999:
By default, eclipse help server uses port 9999. This can be changed by reconfiguring the eclipse help server
6) Loopback Ports:
Also, whenever the ITM components including agent started, there are few outbound loopback ports allocated. Below is the some example for loopback ports:
127.0.0.1.1052
127.0.0.1.1053
127.0.0.1.1054
127.0.0.1.1052
127.0.0.1.1053
127.0.0.1.1054
7) PORT 1978:
Default port 1978 is used by the remote deployment process
NOTE: The loopback and the default remote deployment ports cannot be directed to specific port range
