3.5.4 Traffic Management PVC Priority Assignments Screen Example
Figure 3-7 Example Traffic Management PVC Priority Assignments Screen
The user has two boards connected to an ATM switch and each configured as above. The ATM
switch is configured properly for all three PVCs. A server is in board A and a client in board B.
Traffic will traverse between the two boards according to the rules defined in the 802.1P Priority
Transmit Queue Mapping table. If the client server traffic is assigned to have a priority of 1 on
each board, then the traffic between the client and server will traverse between the two boards on
the PVC 0,50. If the client server traffic had been configured on each board to have a priority of 6
associated with it then all traffic between the client and server would be going across the ATM
cloud on PVC 0,52.
The statistics this traffic creates will appear on the INTERFACE STATISTICS screen as well as
the SWITCH STATISICS screen displayed as interface 32. The statistics shown will however be a
combined total of all of the PVCs configured for the interface (Virtual Port) displayed, not for a
specific PVC on that Virtual Port.
