The following command is used, with a propagation delay threshold value of 2-3 times the measured propagation delay for the hop being a safe value. This is also referred to as the peer delay threshold. If media converters are being used it may be necessary to adjust the propagation delay threshold for the connected port. It is useful for debugging when the summary "show avb" command shows that the port is not operational for gPTP. Use this command to view the gPTP properties of one or more ports. Use this command to view the gPTP properties of all ports, it is the same data shown under " show avb". MVRP status : Enabled and and active " * " on connected ports.Tesira control ports will have active status " * " only. You should see "a" or "ab" next to the ports connected to AVB devices. MSRP status : Enabled and and active " * " on connected ports.Tesira control ports will have a "d" status. You should see "m" or "s" next to the port connected to AVB devices all other ports will likely have the status “d” (disabled, from a clocking perspective). gPTP status : Enabled and and active " * " on connected ports.The "show avb" command will provide details on: To show details of MVRP and MSRP status:.The 'show vlan' command also reveals the management IP address for the VLANs on the switch. There should be a vlan called “SYS_VLAN_0002” which should have a list of the ports participating in AVB streams. Some other msrp command variations are shown below. Adding the text port to the end of the command string allows you to filter by one or more ports, rather than all. Other commands can be useful for identifying talker and listener ports and tracing stream activity. This will also minimize AVB messages from any unused AVB enabled ports when troubleshooting AVB network issues.
This can be useful when connecting the AVB network to a corporate network where traffic from AVB protocols may need to be limited. Use this in place of the line enable avb port all
In this example ports 1, 5, 6, 7, and 12 are being AVB enabled.
