Once it is initially configured via serial connection I can remote in via Telnet (I use Putty), I then create the ACL to permit inbound traffic for the IP address of the Russound MCAC5 to the port the russound is attached to.
The channel will be refreshed with the new representation after processing.If the refreshed representation doesn't include the changes, the russound system rejected them for some reason (generally length of the name).
