DESCRIPTION
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/USG 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/USG 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/USG 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.
This is how the ZyWALL/USG handles the DSCP value of the incoming and outgoing
packets that match this policy.
In - Inbound, the traffic the ZyWALL/USG sends to a connection's initiator.
Out - Outbound, the traffic the ZyWALL/USG sends out from a connection's initiator.
If this field displays a DSCP value, the ZyWALL/USG applies that DSCP value to the
route's outgoing packets.
preserve means the ZyWALL/USG does not modify the DSCP value of the route's
outgoing packets.
default means the ZyWALL/USG 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.
