Important Considerations
■
When you enter the command, the module prompts you to enter the
percentage of bandwidth to use for high-priority traffic on the output
link.
■
The value
75
specifies that three high-priority packets are transmitted
for each best effort packet.
■
The value
50
sets equal priority for high priority and best effort
packets.
■
The value
100
is strict prioritization; it allows best effort packets to be
sent only when no high priority packets need to be sent.
