Chapter 10 Switch Setup

IES-612-51 User’s Guide

10.2.2 Port Isolation with Standalone Switch Mode Example

The following graphic shows IES-612-51 1 and 2 connected to each other and the Ethernet

backbone switch (3) in a network topology that creates a loop. The IES-612-51 are using the

standalone switch mode and have RSTP enabled.

In this example, both IES-612-51 have port isolation turned on. Communications between A

and B must first go through another switch (3 in the figure). However, A and B can

communicate with C without their communications going through another switch or router.

10.2.3 Daisychain Switch Mode

Daisychain switch mode sets the IES-612-51 to use Ethernet port one (ENET 1) as an uplink

port to connect to the Ethernet backbone and Ethernet port two (ENET 2) to connect to another

(daisychained or subtending) IES-612-51. The daisychain switch mode is recommended for

use in a network topology that does not have loops. When you daisychain multiple IES-612-51

they must all be set to daisychain mode.

Daisychain switch mode with port isolation enabled blocks communications between

subscriber ports on an individual IES-612-51 and between the subscribers of any daisychained

IES-612-51 (see Figure 44 on page 99 for an example). Use the same port isolation setting on

all IES-612-51 that you set up in a daisychain.

10.2.4 Port Isolation with Daisychain Switch Mode Example

In the example below, the IES-612-51 1 has its Ethernet port one (ENET 1) connected to the

Ethernet backbone switch (3) and it’s Ethernet port two (ENET2) connected to Ethernet port

one (ENET 1) of the daisychained IES-612-51 (2).
