Operating Notes
• You should have a managed gigabit switch with 8K (or greater) jumbo-frame capability.
• The Matrix Controller has been tested with both Cisco and NetGear switches.
However, performance and results may vary between depending upon the switch that
is used and your network.
• The “discovery” feature, used by the Matrix Controller, relies on a proprietary network
broadcast protocol that is used for identication of Gefen KVM over IP products.
Broadcast packets and access using ports 53334 and 53335 is required for this
feature to work.
• The Gefen Video-over-IP product line is compatible with a wide variety of data
switches:
► For simple installations, the Netgear GS724T / GS748T / GS748TPS (PoE
version) are low-cost 24-port or 48-port Gigabit Smart Switches that meet all
necessary requirements. They have two SFP ports that can be equipped with
ber SFP modules for greater distances.
► For cascaded or extended switch architecture, more than 1 Gigabit bandwidth
may be required between switches. For these situations, the Netgear PROSAFE
GS728TXS Gigabit Stackable Smart Switch offers four 10-Gigabit SFP uplink
ports for expanded bandwidth between switches.
► Other Gigabit managed switches, such as the Cisco Small Business SG300
or SG500X (“X” indicates 10G SFP uplink port) switches may also be used.
However, the conguration will be up to the user.
• In order to properly manage the video trafc, both Jumbo Frames and IGMP Snooping
must be enabled.
Netgear GS7xxT-series switches:
1. Login to the switch with a Web browser.
2. Go to the Switching tab and select Ports > Port Conguration.
3. Check the All checkbox, and set Maximum Frame Size to 9216.
4. Click Apply to save the settings.
5. Go to Multicast > IGMP Snooping > IGMP Snooping Conguration.
6. Enable IGMP Snooping Status.
7. Disable Validate IGMP IP Header.
8. Click Apply to save the settings.
9. Go to IGMP Snooping VLAN Conguration.
10. Enter 1 under Vlan ID.
11. Enable Fast Leave Admin Mode and Query Mode.
12. Click Apply to save the settings.
