List of AVB reservation errors
code error resolution
1 Out of bandwidth There is not enough bandwidth on the path from the talker to the listener.
• Check that all the bridges in use are have a speed of 1 Gb/s (minimum).
• Check the conguration of the bridges: some allow a higher bandwidth
allocation for AVB streams (default is 75% of link speed).
• Change the stream format: select a lower sampling rate, reduce the
number of channels if some are unused.
• Optimize the stream and channel usage: for each talker, use the minimum
number of streams and the maximum number of channels per stream.
• Disconnect some of the already connected streams to release bandwidth.
2 Out of bridge resources One of the bridges on the path from the talker to the listener reached its limits.
• Try to reboot the bridges on the path from the talker to the listener.
• Try to disconnect some streams.
3 Out of bandwidth for trafc
class
See error 1.
4 Stream ID used by another
talker
A device on the network is behaving incorrectly.
• Disconnect and reconnect the stream.
• Reboot the talker.
• Reboot the bridges on the path from the talker to the listener.
• If the talker supports manual conguration of the stream parameters,
congure the stream to use another Stream ID.
5 Stream dest. addr. already in
use
A device on the network is behaving incorrectly.
• Disconnect and reconnect the stream.
• Reboot the talker.
• Reboot the bridges on the path from the talker to the listener.
• If the talker supports manual conguration of the stream parameters,
congure the stream to use another Stream ID.
6 Stream preempted by higher
rank
An emergency stream has been connected and reclaimed the bandwidth that
was used by the Unit stream.
• Wait until the emergency stream is disconnected (bandwidth is
automatically reallocated).
• Try the resolutions of error 1.
