I asked the same question less than a month ago.

They ARE the TCPIP PORT numbers. Yes, TSM will use high numbers (5-digits)
as will many other products that want to stay out of the way of other
products (for an example you can relate to, iManager on a Netware server
uses port 51443 by default).

Port 1501 is what the TSM server uses, by default, to contact the TSM
clients, per this paragraph from the TSM Netware Client book, discussing
the TCPCLIENTPORT parm:

client_port_address  - Specifies the TCP/IP port address you want the
server to use to contact your client node. The range of values is 1000
through 32767; the default is 1501.

FWIW, when doing port blocking/filtering, 1500 & 1501 should be open to
allow TSM through, both directions.

1501?






Hello,


What does the four-digits represent at the end of the Nodes IP?
is that the port it's trying to reach? I have notice other four
digit numbers that are not ports and mean nothing and five digits
numbers
so I assume they mean nothing.

Thanks  for any responses!
