19.3 Other Applications

Sometimes, the NXC cannot identify the application. For example, the application
might be a new application, or the packets might arrive out of sequence. (The NXC
does not reorder packets when identifying the application.)
The Other (applications) screen controls the default policy for TCP and UDP traffic
that the NXC cannot identify. You can use source zone, destination zone,
destination port, schedule, user, source, and destination information as criteria to
create a sequence of specific conditions, similar to the sequence of rules used by
firewalls, to specify what the NXC should do more precisely. You can also control

DESCRIPTION
Type how much inbound bandwidth, in kilobits per second, this policy
allows the application to use. Inbound refers to the traffic the NXC sends
to a connection's initiator.
If you enter 0 here, this policy does not apply bandwidth management
for the application's traffic that the NXC sends to the initiator. Traffic with
bandwidth management disabled (inbound and outbound are both set to
0) is automatically treated as the lowest priority (7).
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.
Type how much outbound bandwidth, in kilobits per second, this policy
allows the application to use. Outbound refers to the traffic the NXC
sends out from a connection's initiator.
If you enter 0 here, this policy does not apply bandwidth management
for the application's traffic that the NXC sends out from the initiator.
Traffic with bandwidth management disabled (inbound and outbound are
both set to 0) is automatically treated as the lowest priority (7).
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.
This field displays when the inbound or outbound bandwidth
management is not set to 0. Enable maximize bandwidth usage to let
the traffic matching this policy "borrow" any unused bandwidth on the
out-going interface.
After each application gets its configured bandwidth rate, the NXC uses
the fairness- based scheduler to divide any unused bandwidth on the
out-going interface amongst applications that need more bandwidth and
have maximize bandwidth usage enabled.
Select whether to have the NXC generate a log (log), log and alert (log
alert) or neither (no) when the application's traffic matches this policy.
