Chapter 28 Application Patrol

Table 133 AppPatrol > Other (continued)

LABEL

DESCRIPTION

Destination

This is the destination address or address group for whom this policy

 

applies. If any displays, the policy is effective for every destination.

 

 

Protocol

This is the protocol of the traffic to which this policy applies.

 

 

Access

This field displays what the ZyWALL does with packets that match this

 

policy.

 

forward - the ZyWALL routes the packets.

 

Drop - the ZyWALL does not route the packets and does not notify the

 

client of its decision.

 

Reject - the ZyWALL does not route the packets and notifies the client

 

of its decision.

 

 

DSCP Marking

This is how the ZyWALL handles the DSCP value of the outgoing packets

 

that match this policy.

 

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

 

Out - Outbound, the traffic the ZyWALL sends out from a connection’s

 

initiator.

 

If this field displays a DSCP value, the ZyWALL applies that DSCP value

 

to the route’s outgoing packets.

 

preserve means the ZyWALL does not modify the DSCP value of the

 

route’s outgoing packets.

 

default means the ZyWALL 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.

 

See Assured Forwarding (AF) PHB for DiffServ on page 293 for more

 

details.

 

 

BWM

These fields show the amount of bandwidth the traffic 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 matching traffic to use. Inbound refers to the traffic the

 

ZyWALL sends to a connection’s initiator. If no displays here, this policy

 

does not apply bandwidth management for the inbound traffic.

 

Out - This is how much outgoing bandwidth, in kilobits per second, this

 

policy allows the matching traffic to use. Outbound refers to the traffic

 

the ZyWALL sends out from a connection’s initiator. If no displays here,

 

this policy does not apply bandwidth management for the outbound

 

traffic.

 

Pri - This is the priority for the traffic that matches this policy. The

 

smaller the number, the higher the priority. Traffic with a higher priority

 

is given bandwidth before traffic with a lower priority. The ZyWALL

 

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.
