| Configuring Network Settings | 72Parameter Description Configuration MethodData Priority Configure the DSCP(Differentiated Services CodePoint) for data packets.Note: the default value is 63.The greater the number is, thehigher the priority is. If youchange this parameter, thesystem will reboot to make thechange take effect.Web user interfaceEndpointCTP20Configuring MTUData packets that exceed the maximum transmission unit (MTU) size for any router or segment along the networkpath may be fragmented or dropped, which may result in poor quality video at the receiving device. You can set themaximum MTU size of the data packets sent by the system.About this taskConfigure the MTU size used in calls based on the network bandwidth settings. If the video becomes blocky ornetwork errors occur, packets may be too large; decrease the MTU. If the network is burdened with unnecessaryoverhead; packets may be too small, increase the MTU.Procedure1. Do one of the following:• On your web user interface, go to Network > Advanced > MTU.• On your VCS:For VC880/VC800/VC500/PVT980/PVT950,On your VC200, go to More > Network > Wired Network > Advanced Network > Network MTU(1000-1500).On your VP59, tap Setting > Advanced > Advanced Network > Network MTU (1000-1500).• On your CTP20, tap Setting > Advanced > Advanced Network > Network MTU (1000-1500).2. Configure and save the following settings:Parameter Description Configuration MethodNetwork MTU (1000-1500) Specify the maximum MTU size(bytes) of data packets sent bythe system.Note: the value can be anyinteger from 1000 to 1500. Thedefault value is 1500.If you change this parameter, thesystem will reboot to make thechange take effect.Web user interfaceEndpointCTP20
