Ethernet Network Configurations in Managed Switch Mode

I.3.1 Point-to-Multipoint Hub-to-Remotes, Split-path Traffic Using
Routers
Figure I-8 shows hub-to-remotes configuration using routers with standard and split-path Ethernet
traffic. A Static ARP Entry is needed in the switch so that routing of the Tx side of the modems
will be on the correct port of the router. For example, the Rx side of the Ethernet connection for
'Traffic Modem #N' comes in the bottom port of the Router, but the Tx Ethernet connection must
be connected through the same port as 'Traffic Modem #1', as shown in this figure.
