Setup Connecting Your IRIS DC1100 1. Place your IRIS DC1100 in a location where it will be well ventilated. Do not stack it with other devices or place it on carpet. 2. Connect your WAN equipment Ethernet port with CAT5 cross over cable to IRIS DC1100 Ethernet Port. If connecting to a hub or switch use a CAT5 straight through cable. 3. For coaxial connections determine the model number of the IRIS unit. The following models come with integrated fully agile 256 QAM DOCSIS Upconverter.
Coaxial Cable Specifications The coaxial cable used to connect the IRIS DC1100 series universal broadband routers at the Headend should be very high-quality cable. Coaxial recommends that you use a Headend-grade coaxial cable or a quad-shield coaxial cable with a minimum of 60% + 40% braid and double foil insulation to connect the cable modem cards to the HFC network. The center conductor must be straight and extend 1/8 inch (3.

When connecting to a switch a straight Cat5 Ethernet cable will be required.
Configuration Configuring IRIS All IRIS systems can operate in Bridge or Routing mode with NAT enabled on the cable interface. At the time of shipping the system IRIS is configured to work in the routing mode with NAT enabled on the cable interface. When NAT is enabled IRIS routes packets from its cable interface to the Ethernet interface and vice-versa. The diagram below represents the IP network topology with such configuration.
Connecting using Web Interface Start your Internet browser and point it to http://192.168.21.1:2380. You will be prompted by the “IRIS Admin” login window. Please enter the User name and Password to authenticate. All IRIS systems ship with default user name “iris” and password “123456”. IRIS Setup home page will appear in your browser as shown in Figure 9. Figure 8 Web Login Figure 9 Setup home page Coaxial Networks, Inc.
The Web interface can be used to configure the following parameters 1. 2. 3. 4. 5. 6. 7. 8. TCP/IP parameters IRIS Operational mode Web login password Cable modem subscription Cable modem tftp configuration file generation for QOS Downstream channel, QAM mode and Output power level Upstream frequency for each channel Report cable modem status Configuring TCP/IP parameters To configure TCP/IP parameter for IRIS or to set its operational mode click on the “Network” on the left hand side navigational menu.
Configuring IRIS in Router mode All IRIS systems ship with operational mode set to “router”. In router mode the cable interface is configured with a private interface and all cabled modems and CPEs attached to the cable modems are automatically assigned IP addresses from this private addressing scheme. You will need to configure the “Uplink Interface” or the Ethernet Interface with the ISP provided configuration parameters.
Configuring IRIS in Bridge mode To configure IRIS in “bridge” mode select “Network” from the navigation menu bar. If you configure IRIS in bridge mode, you will need to use an external provisioning server that can provide all the required server functionality which includes DHCP server, TFTP server and TOD server. Figure 12 Network Setup You will also need to configure you provisioning server so that it can allocate IP addresses to CPE devices that are behind the cable modems.
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.

Configuring Downstream RF Settings DOCSIS protocol utilizes an available channel to send downstream signal for data communications. Depending upon the frequency plan NTSC or PAL, IRIS automatically provides you the channel number and the center frequency in a drop down menu. Figure 15 Downstream RF Settings Using the “Center frequency with channel number” select the channel that you wish to use to send downstream signal. This channel should not be used to send any video signal.
Configuring Upstream RF Settings DOCSIS protocol utilizes a separate upstream frequency to provide upstream data communication back from the cable modem. Your cable plant has to be two way ready or return passing to provide high speed data communication over cable. The North American plan uses up to a 3.2MHz wide channel in the 5-42MHz frequency range. The European plan uses up to a 3.2 MHz wide channel in the 5-65MHz frequency range.
Creating Class of Service Profiles DOCSIS based data networks allow each cable modem to be associated to a class of service. This class of service configuration is downloaded by the cable modem during registration process using TFTP protocol. IRIS provides a user interface using which you can enter different values for a cable modem configuration file and then save these settings to class of service.
In the “US Priority” specify the priority that you wish to assign traffic coming from this cable modem in the upstream direction. IRIS supports 1 to 7 upstream priority classifications, 1 being the highest. In the “Guaranteed US Rate” specify upstream data rate which you wish to guarantee for each cable modem. For example for voice traffic a guaranteed upstream rate of 64000 is recommended.
Controlling Cable Modem Access IRIS can allow all or selectively allow cable modems connected to your cable network to gain access to the Internet. ) By default IRIS is configured such that all modems that are connected on your cable plant can gain access to the Internet. To enable conditional access to certain we need to enable conditional access and then add the MAC addresses of the cable modems. Once it has been done only cable modems with these MAC addresses can register with IRIS.
the location of each cable modem and also associate the cable modem to one of the class of service profiles you have created. If you have not created any class of service profiles, create a class of service using the “CM configuration” option. A cable modem that had yet not been connected to the cable network will not show up in the “unsubscribed modems” list.
You will need to save the “subscribed modems” list so that the same is available after a system restart. Press the “Save” button to save or update the “subscribed modems” list to the flash memory of IRIS. Coaxial Networks, Inc.
IRIS CLI interface using Telnet IRIS also provides a CLI interface for certain advanced configuration and diagnostics. You will need a PC to connect using telnet. You should be able to connect to IRIS from the HFC side if you have successfully been able to bring up a cable modem. The easiest way to connect to IRIS is from the Ethernet interface of IRIS.
Using a serial (RS232) 9 pin null modem cable connect your PC’s serial port to the serial console port of IRIS. Now you can use tools such as “HyperTerminal” in Windows to connect to IRIS. The settings for the serial console port of IRIS are Baud Rate: 57600 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None After successfully connecting to the console port you should see the IRIS “login” prompt. Logging In At the login prompt, type the username as “iris” and hit enter.

Application Notes Network traffic between cable clients By default IRIS does not allow traffic between CPEs behind cable modems on the same IRIS. To enable this you have to turn the “NetLoopbackMode” setting in iris.txt file to “1”. Edit the “iris.txt” file from the system prompt and then change the above seeting to NetLoopbackMode = 1 Save the file and restart IRIS. Allowing PPPoE traffic across IRIS By default IRIS is configured to forward Ethernet packets of IP protocol type only.
To create a BIMAP you will need to know the MAC address of the CPE. To obtain this you can Telnet to IRIS and issue the "pcpe" command find the cable modem that the end user has, attached you will see his CPE Mac address. Assigning a reserved IP address to the CPE. Edit the /etc/dhcpd.conf file and add a "host" entry for the MAC address of the CPE with a Reserved IP address in the "#CPE Network" subnet host user1 { hardware ethernet 00:12:17:4C:9b:21; fixed-address 10.71.0.

VI (Visual) Editor The vi is a text editor. It is small, powerful, and standard on most UNIX systems. The vi often frustrates new users with a unique distinction between its two modes: Command Mode and Insert/Overtype Mode. This distinction, although difficult to become accustomed to for many users, provides great power and ability to the editor. Insert/Overtype Mode is designed for inserting text only. All text manipulations and cursor moving should be done from with in Command Mode.
