Figure 13 Bridge mode setup
This will change the IRIS Setup screen so that the system can be configured in the bridge mode.
In bridge mode IRIS only has one interface, which is the “cable” interface. IRIS then forward all
traffic from the HFC side to the Ethernet side.
If you are planning to use the DHCP server available on IRIS do not change “Cable CM
Interface” address. If you change this address and plan to use DHCP server on IRIS to assign IP
addresses to the cable modems make sure that the DHCP configuration file has appropriately
been updated.
Using the Alias Interface you can assign another IP address configuration to IRIS; this could be
useful if you wish to assign a public IP address to IRIS.
