P-660H-Tx v2 Support Notes
Fairness-Based is chosen, then the bandwidth is allocated by ratio. Which
means if A class needs 300 kbps, B class needs 600 kbps, then the ratio of A
and B's actual bandwidth is 1:2. So if we get 450 kbps in total, then A would
get 150 kbps, B would get 300 kbps. We select Priority-Based in this
example.
Key Settings:
Active
Check the box to enable BWM on the interface. Note that if you would like
to manage traffic from WAN to LAN, you should apply BWM on LAN
interface. If you would like to management traffic from WAN to DMZ,
please apply BWM on DMZ interface.
Speed
Enter the total speed to manage on this interface. This value is the budget
of the class tree's root.
Scheduler
Choose the principle to allocate bandwidth on this interface.
Priority-Based allocates bandwidth via priority. Fairness-Based allocates
bandwidth by ratio.
Maximize
Bandwidth
Usage
Check this box if you would like to give residuary bandwidth from Interface
to the classes who need more bandwidth than configured amount. Do not
select this if you want to reserve bandwidth for traffic that does not match a
bandwidth class or you want to limit the bandwidth of each class at the
configured value. (Please note that to meat the second condition, you
should also disable Use All Managed Bandwidth in the BWM rule.)
Step 2: Go to Web Configurator, Advanced Setup, Advanced -> Bandwidth
MGMT-> Rule Setup, select the interface, Service, Priority, and Allocated
Bandwidth for this rule, then click button ‘Add’ to apply this rule.
