Schedule

Select a schedule that defines when the policy applies or select Create
Object to configure a new one. Otherwise, select none to make the
policy always effective.

User

Select a user name or user group to which to apply the policy. Use
Create new Object if you need to configure a new user account. Select
any to apply the policy for every user.

From

Select the source zone of the traffic to which this policy applies.

Select the destination zone of the traffic to which this policy applies.

Source

Select a source address or address group for whom this policy applies.
Use Create new Object if you need to configure a new one. Select any
if the policy is effective for every source.

Destination

Select a destination address or address group for whom this policy
applies. Use Create new Object if you need to configure a new one.
Select any if the policy is effective for every destination.

Access

This field controls what the NXC does with packets for this application
that match this policy. Choices are:

forward - the NXC routes the packets for this application.

Drop - the NXC does not route the packets for this application and does
not notify the client of its decision.

Reject - the NXC does not route the packets for this application and
notifies the client of its decision.

DSCP Marking

Set how the NXC handles the DSCP value of the outgoing packets that
match this policy. Inbound refers to the traffic the NXC sends to a
connection’s initiator. Outbound refers to the traffic the NXC sends out
from a connection’s initiator.

Select one of the pre-defined DSCP values to apply or select User
Defined to specify another DSCP value. The “af” choices stand for
Assured Forwarding. The number following the “af” identifies one of four
classes and one of three drop preferences.

Select preserve to have the NXC keep the packets’ original DSCP value.

Select default to have the NXC set the DSCP value of the packets to 0.

The “wmm” entries are for QoS. For more information on QoS and WMM
categories, see

page 209

Bandwidth
Management

Configure these fields to set the amount of bandwidth the application
can use. These fields only apply when Access is set to forward.

You must also enable bandwidth management in the main application
patrol screen (AppPatrol > General) in order to apply bandwidth
shaping.
