12.3 Support for VLAN Tagging
The Ethernet card supports the automatic creation of two VLANs or Virtual Local Area Networks. This feature may be used to
allow both routing the streaming of the output video and access to the GUI on two separate virtual networks as if there were
two separately wired physical networks installed. In VLAN tagging, the broadcast domain is extended across the VLAN as if
the devices in the group were all locally connected together. VLANs also extend the DHCP server requests across the same
virtual network if DHCP is used to assign network addresses. In this way the GUI and streaming IP output may be assigned
addresses independently from two separate pools or DHCP servers.
Without the use of VLANs, the GUI port may be connected to any of the GbE ports since the four GbE ports are configured as
an IP switch, and any other GbE port may be connected to a local switch or access network such as a cable modem. In this
manner a single path to the central headend may be used to carry both management and streaming video. The disadvantage
of this method is that at the central headend consolidation switch, and depending on the type of switch, the streams may all
appear on the destination device port such that a management computer may have streaming video from many DVIS devices
routed to it and conversely, the video receiving device may experience undesired management traffic.
By using VLANs, the video and management access streams, while arriving together, are separated at the destination switch
into two distinct VLAN groups, each routed to a specific physical port defined by the VLAN. In this way all streaming video will
be routed to the video receiving device, like a CherryPicker and the management access will be routed to the management
computer(s). In this way only traffic intended for a receiving device will receive it. Since broadcast domains are extended over
VLANs, all of the features of a broadcast domain are extended across the VLAN as well. See
for specific details on this.
12.4 Gigabit Ethernet Card Fundamentals
12.4.1 SFP Support
The card supports two SFP modules (Small Form-Factor Pluggable) allowing single mode and multi-mode optical modules to
interface to the GbE ports providing long range and secure interfaces to switches, routers and remote sites. Many types and
manufacturers of SFP have been tested with good results but because of the vast offering of various SFP modules, it is not
possible to test all of them. It remains up to the customer to verify that his SFP will work as expected.
12.4.2 Integrated Switch
The Gigabit Ethernet card integrates a GbE switch on board allowing the card to transmit simultaneously from up to 4 Ethernet
ports; 2 copper RJ45 type ports and 2 SFP ports. SFP Modules must be purchased separately and so far, SFP modules that
are incompatible have not been identified.
12.4.3 Protocol Support
The card supports DHCP, ICMP and ARP protocols as well as VLAN tagging. Before unicast transmission is started the
card will first attempt to find the destination MAC address of the receiving side (when using unicast transmission) using ARP
protocol. When the MAC address is found, transmission begins.
12.5 Quick Guide to the Gigabit Ethernet Card
If more information is required, see the detailed configuration descriptions following this quick guide.
1. Insert the Gigabit Ethernet card into slot 2 (DVISm) or 5 (DVIS).
2. Open the ‘Mux’ tab and change the ‘Output Selection’ to either ‘Ethernet Only’ or to ‘RF & Ethernet’.
3. Verify insertion and detection of the card on the ‘Encoder Settings’ tab – Card is detected as ‘ETH1000’.
4. Open the IP Output tab and configure the Gigabit Ethernet Card with the following parameters as required:
•
Source IP Settings:
◦
IP Address – The IP address of the Ethernet Card physical interface. Only one required for all 4 ports.
◦
Subnet Mask – Identifies the subnet of the IP address specified above.
◦
Source Port – Source port that will be specified when sending the TS data.
◦
Enable DHCP Client – When selected, the Gigabit Ethernet Card will obtain a dynamic IP address
(Source address) from a DHCP server and use this address for all Ethernet transmissions. A source
port is not obtained from a DHCP server.
•
Destination IP Settings:
◦
IP Address – The IP address that the Gigabit Ethernet Card transmits to.
◦
Destination Port – The virtual destination port that is used for the TS data transmission.
