or TCP/UDP port number. Then specify the volume of bandwidth you want to
allocate to the filtered traffic.
Using BWM
Go to ADVANCED->BW MGMT->Summary, activate bandwidth management on
the interface you would like to manage. We enable the BWM function on WAN1
interface in this example.
Enter the total speed for this interface that you want to allocate using bandwidth
management. This appears as the bandwidth budget of the interface’s root class.
Select how you want the bandwidth to be allocated. Priority-Based means bandwidth
is allocated via priority, so the traffic with highest priority would be served first, then
the second priority is served secondly and so on. If 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.
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 bandwidth borrowing
on the class.)
Go to ADVANCED->BW MGMT->Class Setup, select the interface on which you
would like to setup the Class tree.
Click the radio button besides the Root Class, then press 'Add Sub-Class'
