Chapter 26 Bandwidth Management Table 119 Configuration > Bandwidth Management > Add/Edit LABEL Inbound Marking Outbound Marking DESCRIPTION Inbound refers to the traffic the UAG sends to a connection's initiator. Outbound refers to the traffic the UAG 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 163 for more details. Select preserve to have the UAG keep the packets' original DSCP value. Bandwidth Management Inbound kbps Select default to have the UAG 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 UAG sends to a connection's initiator. If you enter 0 here, this policy does not apply bandwidth management for the matching traffic that the UAG 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). Outbound kbps 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. Type how much outbound bandwidth, in kilobits per second, this policy allows the traffic to use. Outbound refers to the traffic the UAG sends out from a connection's initiator. If you enter 0 here, this policy does not apply bandwidth management for the matching traffic that the UAG sends out from the initiator. Traffic with bandwidth management disabled (inbound and outbound are both set to 0) is automatically treated as the lowest priority (7). Priority 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. This field displays when the inbound or outbound bandwidth management is not set to 0. Enter a number between 1 and 7 to set the priority for 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 uses a fairness-based (round-robin) scheduler to divide bandwidth between traffic flows with the same priority. Maximize Bandwidth Usage The number in this field is ignored 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 field displays when the inbound or outbound bandwidth management is not set to 0. Enable maximize bandwidth usage to let the traffic matching this policy "borrow" any unused bandwidth on the out-going interface. OK Cancel After each application or type of traffic gets its configured bandwidth rate, the UAG uses the fairness- based scheduler to divide any unused bandwidth on the out-going interface amongst applications and traffic types that need more bandwidth and have maximize bandwidth usage enabled.

Chapter 26 Bandwidth Management
UAG715 User’s Guide

Inbound
Marking
Outbound
Marking
Inbound refers to the traffic the UAG sends to a connection’s initiator. Outbound refers to
the traffic the UAG 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 163
for more details.
Select
preserve
to have the UAG keep the packets’ original DSCP value.
Select
default
to have the UAG set the DSCP value of the packets to 0.
Bandwidth
Management
Configure these fields to set the amount of bandwidth the matching traffic can use.
Inbound
kbps
Type how much inbound bandwidth, in kilobits per second, this policy allows the traffic to
use. Inbound refers to the traffic the UAG sends to a connection’s initiator.
If you enter
0
here, this policy does not apply bandwidth management for the matching
traffic that the UAG 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.
Outbound
kbps
Type how much outbound bandwidth, in kilobits per second, this policy allows the traffic to
use. Outbound refers to the traffic the UAG sends out from a connection’s initiator.
If you enter
0
here, this policy does not apply bandwidth management for the matching
traffic that the UAG sends out from 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.
Priority
This field displays when the inbound or outbound bandwidth management is not set to 0.
Enter a number between 1 and 7 to set the priority for 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 uses a fairness-based (round-robin) scheduler to divide bandwidth between
traffic flows with the same priority.
The number in this field is ignored 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.
Maximize
Bandwidth
Usage
This field displays when the inbound or outbound bandwidth management is not set to 0.
Enable maximize bandwidth usage to let the traffic matching this policy “borrow” any
unused bandwidth on the out-going interface.
After each application or type of traffic gets its configured bandwidth rate, the UAG uses
the fairness- based scheduler to divide any unused bandwidth on the out-going interface
amongst applications and traffic types that need more bandwidth and have maximize
bandwidth usage enabled.
