31.2.1
The Bandwidth Management Add/Edit Screen
The
Configuration > BWM Add/Edit
screen allows you to create a new condition or edit an
existing one. To access this screen, go to the
Configuration > BWM
screen (see
Section 31.2 on
page 370
), and click either the
Add
icon or an
Edit
icon.
Incoming
Interface
This is the source interface of the traffic to which this policy applies.
Outgoing
Interface
This is the destination interface of the traffic to which this policy applies.
Source
This is the source address or address group for whom this policy applies. If
any
displays,
the policy is effective for every source.
Destination
This is the destination address or address group for whom this policy applies. If
any
displays, the policy is effective for every destination.
DSCP Code
This is
the DSCP value of the incoming or outgoing packets to which this policy applies.
any
means all DSCP values or no DSCP marker.
default
means traffic with a DSCP value of 0. This is usually best effort traffic.
Service
This is the service object to which this policy applies. If
any
displays, the policy is effective
for every service.
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 UAG 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 UAG 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 UAG
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 UAG handles the DSCP value of the incoming and outgoing packets that
match this policy.
preserve
means the UAG does not modify the DSCP value of the route’s packets.
default
means the UAG sets the DSCP value of the route’s packets to 0.
If this field displays a DSCP value, the UAG applies that DSCP value to the route’s packets.
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 12.4 on page 212
for
more details.
