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).
