DESCRIPTION

#

This field is a sequential value, and it is not associated with a specific

 

condition.

 

Note: The ZyWALL checks conditions in the order they appear in

 

the list. While this sequence does not affect the functionality,

 

you might improve the performance of the ZyWALL by putting

 

more common conditions at the top of the list.

 

 

Destination

This field displays the specific port number to which this policy applies.

Port

 

 

 

Schedule

This is the schedule that defines when the policy applies. any means the

 

policy always applies.

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

 

 

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 309 for more

 

details.
