Configuring MTU
Data packets that exceed the maximum transmission unit (MTU) size for any router or segment along the
network path may be fragmented or dropped, which may result in the poor video quality. You can set the
maximum MTU size of the data packets sent by the system.
About this task
Configure the MTU size used in calls based on the network bandwidth settings. If the video becomes
blocky or network errors occur, packets may be too large; you should decrease the MTU. If the network is
burdened with unnecessary overhead; packets may be too small, you should increase the MTU.
