A.4 Configuring the switches and devices

The layout is vital but so too is the configuration:

• Enable

IGMP Snooping

on all L2 switches.

• Ensure that

IGMP Fast-Leave

is enabled on all switches with ServSwitch Agility units connected directly to them.

• Enable the L3 switch as an

IGMP Querier

• Enable

Spanning Tree Protocol (STP)

on all switches and importantly also enable portfast (only) on all switch ports that

have ServSwitch Agility units connected.

• If any hosts will use any video resolutions using 2048 horizontal pixels (e.g. 2048 x 1152), ensure that

Jumbo Frames

are

enabled on all switches.

• Choose an appropriate forwarding mode on all switches. Use

Cut-through

if available, otherwise

Store and forward

• Optimise the settings on the ServSwitch Agility transmitters:

• If color quality is important, then leave Colordepth at 24 bits and adjust other controls,

• If moving video images are being shown frequently, then leave Frame Skipping at a low percentage and instead reduce the

Peak bandwidth limiter and Colordepth.

• Where screens are quite static, try increasing the Background Refresh interval and/or increasing the Frame skipping percent-

age setting.

Make changes to the ServSwitch Agility transmitters one at a time, in small steps, and view typical video images so that you

can attribute positive or negative results to the appropriate control.

• Ensure that all ServSwitch Agility units are fully updated to the latest firmware version (at least v2.1).
