DESCRIPTION

 

 

BWM In/Pri/Out/Pri

This field shows the amount of bandwidth the traffic can use.

 

 

 

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 incoming (the first Pri value) or outgoing (the second

 

 

 

Pri value) 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.

 

 

 

 

 

 

DSCP Marking

This is how the ZyWALL handles the DSCP value of the incoming and 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 Section 10.4 on

 

 

 

page 208 for more details.
