Review!!
SCENARIO: You have a Dante system that seems to be functioning correctly, there are no
external word clocks configured, no preferred master configured, but there are still a number of
devices that report they are losing sync occasionally. What steps would you take to find the root
cause of the problem? - -You suspect that multicast traffic is not able to traverse the network in
both directions (i.e. from master to all slaves, and from all slaves to the master). To check if this
is the case you enable unicast delay requests on the slaves, then monitor the clock status
histogram for evidence of disruption in PTP. When this resolves the problem you suspect that
ACLs blocking multicast on UDP ports 319 and 320 in a direction from the slave to the master is
to blame.
-If IGMP Snooping is enabled, you test the system with no audio and IGMP Snooping turned off.
When this resolves the problem you suspect that IGMP snooping has been interfering with the
distribution of multicast traffic between the slaves and the master. You enable unicast delay
requests on all slaves to reduce the amount of multicast traffic that the switches need to track
via IGMP.
Switches look at ________ - Destination MAC addresses to forward frames
Things to consider when building a network from scratch: - Sizing links for worst case traffic
loads
Dante automatically changes a unicast flow to a multicast flow when necessary. - False
Dante uses ______ DSCP tags. - 4
Apart from separate cabling, a ________ can be used to separate broadcast domains. - VLAN
, In a [________] transaction bandwidth is only consumed on the [________] path between a
receiver and a transmitter. - unicast, shortest
A session is ________ - an instance when a connection between two devices is created to
transfer data
A Dante device can have an unlimited number of receive flows. - False
How do you find out how many transmit flows you are using? - Tx tab in Dante controller
An ARP whohas message is ________ - Broadcast
Giving an external word-clock to a Dante device replaces its internal clock. - False
IGMP snooping listens for reports to [________] messages in order to restrict [________] traffic.
- IGMP query, multicast
ARP tables are held in nodes - True
Match these layer numbers to the corresponding layer names in the OSI model: - Layer 7 -
Application
Layer 6 - Presentation
Layer 5 - Session
Layer 4 - Transport
Layer 3 - Network
Layer 2 - Datalink
Layer 1 - Physical
