4. This port must be configured using the children-local-port parameter in the
[communication-layer] section of the Parent rcproxy.cfg file, in this case
the RC Target Proxy configuration file. This port must be the same as
specified in the parent-remote-port parameter in the [communication-layer]
section of the Child rcproxy.cfg file, in this case the RC Controller Proxy
configuration file.
5. The default polling interval could be changed by configuring the
polling-interval parameter in the [parent-cm-info] section of the Child
rcproxy.cfg file, in this case the RC Controller Proxy configuration file, as it is
the initiator.
6. This default port is for a Remote Control session and could be changed in the
rc_def_ports RC Policy. The default port for a File Transfer session is 2502
and could also be changed in the rc_def_ports RC Policy.
For more information about how to configure the RC Policies or the Proxy
configuration files, refer to the
IBM Tivoli Remote Control User’s Guide

Unidirectional communication with Relay
Table 2-3 describes the same type of communication as detailed in Table 2-1 on
page 63, but a new element, a Relay, has been introduced between the two RC
Proxies. In this situation, the Parent Proxies, which are the RC Target Proxy and
the Relay towards the RC Controller Proxy, are the
initiator
s. The comments
following the table refer to the numbered notes inside the table.
