Channel => [MultiplePorts] What is the effect?


#1

I’m studying zap installation and configuration and see that you can specify multiple ports for a channel with Channel => 1,2,3 or Channel => 1-3.

What is the effect of doing this using multiple ports for a single channel? I’ve been sifting through the wiki and have seen references to using multiple channels, but not what it does.

Thank you,
