Source This is the source address or address group, including geographic address and FQDN
(group) objects, for whom this policy applies. If
any displays, the policy is effective for
every source.
Destination This is the destination address or address group, including geographic address and FQDN
(group) objects, for whom this policy applies. If
any displays, the policy is effective for
every destination.
DSCP Code These are the DSCP code point values of incoming and outgoing packets to which this
policy applies. 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 ” options stand for Assured Forwarding. The number following the “ af ” identifies
one of four classes and one of three drop preferences.
Service App and the service name displays if you selected Application Object for the service
type. An Application Object is a pre-defined service.
Obj and the service name displays if you selected Service Object for the service type. A
Service Object is a customized pre-defined service or another service. Mouse over the
service object name to view the corresponding IP protocol number.
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 Zyxel Device 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 Zyxel Device 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
Zyxel Device 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 Zyxel Device handles the DSCP value of the incoming and outgoing
packets that match this policy.
In - Inbound, the traffic the Zyxel Device sends to a connection’s initiator.
Out - Outbound, the traffic the Zyxel Device sends out from a connection’s initiator.
If this field displays a DSCP value, the Zyxel Device applies that DSCP value to the route’s
outgoing packets.
preserve means the Zyxel Device does not modify the DSCP value of the route’s
outgoing packets.
default means the Zyxel Device 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.
