DESCRIPTION
Select the destination interface of the traffic to which this policy applies.
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.
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.
Select a DSCP code point value of incoming packets to which this policy
route applies or select User Defined to specify another DSCP code point. The lower
the number the higher the priority with the exception of 0 which is usually given only
best-effort treatment.
any means all DSCP value or no DSCP marker.
default means traffic with a DSCP value of 0. This is usually best effort traffic
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
Use this field to specify a custom DSCP code point.
This field is available if you selected Service Object as the service type.
Select a service or service group to identify the type of traffic to which this policy
applies. any means all services.
Set how the ZyWALL handles the DSCP value of the incoming and outgoing packets
that match this policy. Inbound refers to the traffic the ZyWALL sends to a connection's
initiator. Outbound refers to the traffic the ZyWALL 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. See
Section 10.4 on page 208 for more details.
Select preserve to have the ZyWALL keep the packets' original DSCP value.
Select default to have the ZyWALL set the DSCP value of the packets to 0.
Configure these fields to set the amount of bandwidth the matching traffic can use.
Type how much inbound bandwidth, in kilobits per second, this policy allows the traffic
to use. Inbound refers to the traffic the ZyWALL sends to a connection's initiator.
If you enter 0 here, this policy does not apply bandwidth management for the
matching traffic that the ZyWALL sends to the initiator. Traffic with bandwidth
management disabled (inbound and outbound are both set to 0) is automatically
treated as the lowest priority (7).
If the sum of the bandwidths for routes using the same next hop is higher than the
actual transmission speed, lower priority traffic may not be sent if higher priority
traffic uses all of the actual bandwidth.
