4.4. Configuring the Network Switch

IGMP and Other Settings

Configuring the switch correctly will pass data more efficiently, allowing a better stream across the network to
each KVM over IP Extender device. The following settings will help optimize your network traffic through a

switch:

• Enable IGMP Snooping on L2 switches
• Enable IGMP Querier on the L3 switch
• Enable Flow Control
• Enable IGMP Fast-Leave on all switches where KVM over IP Extender units are directly connected
• Enable Spanning Tree Protocol (STP) on all switches and enable Portfast exclusively on switch ports that have KVM

over IP Extender units connected
• Pick an appropriate forwarding mode on all switches. Use Cut-through if available, or Store and Forward
• Enable filtering of unregistered packets

The following table shows the recommended settings for various networking topologies:

Cascaded Switch Networking
Switch Feature Single Switch Networking
Core Switch Extended Switch
Green or energy-saving Disable Disable Disable

Multicast forwarding / filtering Enable Enable Enable

IGMP Snooping Enable Enable Enable
