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 poor quality video at the receiving device.
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; decrease the MTU. If the network is burdened
with unnecessary overhead; packets may be too small, increase the MTU.
Procedure
1. Do one of the following:
• On your web user interface, go to Network > Advanced > MTU.
• On your VCS: go to More > Settings > Network Setting > Wired Network > Advanced Network >
MTU(1000-1500).
For VP59, tap > Settings > Network Setting > Wired Network > Advanced Network >
MTU(1000-1500).
•
On your CTP20/CTP18, tap > Settings > Network Setting > Host Network > Advanced
Network > Network MTU (1000-1500).
2. Configure and save the following settings:
Parameter Description Configuration Method
