Example minna (config) #
minna (config) #
qos classification enable
Description Enables the QoS feature. The QoS classification feature allows you to prioritize both
optimized and pass-through traffic going through this appliance.
The no command option disables QoS.
Syntax [no] qos classification enable
Parameters None
Example
minna (config) # qos classification enable

qos classification link-rate
Description Set the bandwidth link-rate for the specified WAN interface. This is the bottleneck
WAN bandwidth not the interface speed out of the WAN interface into the router or
switch. For example, if your HP EFS WAN Accelerator connects to a router with a
100 Mbps link, do not specify this value—specify the actual WAN bandwidth (for
example, T1, T3).
priority [realtime |
interactive | business |
normal | low]
Specifies a minimum guaranteed QoS priority level:
• Real-Time. Specifies real-time traffic class. Traffic that is your
highest priority should be given this value.
• Interactive. Specifies Interactive traffic class.
• Business Critical. Specifies the business critical traffic class.
• Normal Priority. Specifies normal priority traffic class.
• Low Priority. Specifies low priority traffic class.
Priorities are listed in decreasing order of importance. These are
minimum priority guarantees, if better service is available it is
provided. For example, if a class is specified as Low Priority
and the higher priority classes are not active, then the Low
Priority class is given the highest possible priority for the current
traffic conditions.
min-pct <min> Specifies the bandwidth amount that you want to guarantee for a
specific class. All the classes combined cannot exceed 100%.
During contention for bandwidth the class is guaranteed at least
the amount specified, it will receive more if there is unused
bandwidth remaining.
NOTE: The percentage of excess bandwidth given to a class is
relative to the percentage of minimum bandwidth allocated in the
WAN Bandwidth for Interface field.
conn-limit <num> Specifies a maximum number of connections the specified class
will optimize. Connections over this limit are passed-through
unoptimized.
