DESCRIPTION
Select the service that the client computer sends to a remote server.
The incoming service should have the same service or protocol type as
what you configured in the Service field.
Select a service that a remote server sends. It causes (triggers) the NXC
to forward the traffic (received on the outgoing interface) to the client
computer that requested the service.
This allows you to allocate bandwidth to a route and prioritize traffic that
matches the routing policy.
You must also enable bandwidth management in the main policy route
screen (Network > Routing > Policy Route) in order to apply
bandwidth shaping.
Specify the maximum bandwidth (from 1 to 1048576) allowed for the
route in kbps. If you enter 0 here, there is no bandwidth limitation for
the route.
If the sum of the bandwidths for routes using the same next hop is
higher than the actual transmission speed, lower priority traffic may not
be sent if higher priority traffic uses all of the actual bandwidth.
To reserve bandwidth for traffic that does not match any of the policy
routes, leave some of the interface's bandwidth unbudgeted and do not
enable Maximize Bandwidth Usage.
Enter a number between 1 and 7 to set the priority for traffic. The
smaller the number, the higher the priority. If you set the maximum
bandwidth to 0, the bandwidth priority will be changed to 0 after you
click OK. That means the route has the highest priority and will get all
the bandwidth it needs up to the maximum available.
A route with higher priority is given bandwidth before a route with lower
priority.
If you set routes to have the same priority, then bandwidth is divided
equally amongst those routes.
Select this check box to have the NXC divide up all of the interface's
unallocated and/or unused bandwidth among the policy routes that
require bandwidth. Do not select this if you want to reserve bandwidth
for traffic that does not match any of the policy routes.
Click OK to save your changes back to the NXC.
Click Cancel to exit this screen without saving.
