Chapter 19 Application Patrol

NXC5200 User’s Guide

Access

This field displays what the NXC does with packets for this application
that match this policy.

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

This is how the NXC handles the DSCP value of the outgoing packets
that match this policy.

In - Inbound, the traffic the NXC sends to a connection’s initiator.

Out - Outbound, the traffic the NXC sends out from a connection’s
initiator.

If this field displays a DSCP value, the NXC applies that DSCP value to
the route’s outgoing packets.

preserve means the NXC does not modify the DSCP value of the
route’s outgoing packets.

default means the NXC sets the DSCP value of the route’s outgoing
packets to 0.

The “af” choices stand for Assured Forwarding. The number following
the “af” identifies one of four classes and one of three drop
preferences.

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

page 209

BWM

These fields show the amount of bandwidth the application’s traffic that
matches the policy can use. These fields only apply when Access is set
to forward.

In - This is 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 no displays here, this policy
does not apply bandwidth management for the application’s incoming
traffic.

Out - This is 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 no displays here, this
policy does not apply bandwidth management for the application’s
outgoing traffic.

Pri - This is the priority for this application’s traffic that matches this
policy. The smaller the number, the higher the priority. The traffic of an
application with higher priority is given bandwidth before traffic of an
application with lower priority. The NXC ignores this number if the
incoming and outgoing limits are both set to 0. In this case the traffic is
automatically treated as being set to the lowest priority (7) regardless
of this field’s configuration.
