Chapter 26 Bandwidth Management Priority and Over Allotment of Bandwidth Effect Server A has a configured rate that equals the total amount of available bandwidth and a higher priority. You should regard extreme over allotment of traffic with different priorities (as shown here) as a configuration error. Even though the UAG still attempts to let all traffic get through and not be lost, regardless of its priority, server B gets almost no bandwidth with this configuration. Table 117 Priority and Over Allotment of Bandwidth Effect POLICY CONFIGURED RATE MAX. B. U. PRIORITY A 1000 kbps Yes 1 B 1000 kbps Yes 2 ACTUAL RATE 999 kbps 1 kbps Finding Out More • See DSCP Marking and Per-Hop Behavior on page 155 for a description of DSCP marking. 26.2 The Bandwidth Management Screen The Bandwidth management screens control the bandwidth allocation for TCP and UDP traffic. You can use source interface, destination interface, destination port, schedule, user, source, destination information, DSCP code and service type as criteria to create a sequence of specific conditions, similar to the sequence of rules used by firewalls, to specify how the UAG handles the DSCP value and allocate bandwidth for the matching packets. Click Configuration > BWM to open the following screen. This screen allows you to enable/disable bandwidth management and add, edit, and remove user-defined bandwidth management policies. The default bandwidth management policy is the one with the priority of "default". It is the last policy the UAG checks if traffic does not match any other bandwidth management policies you have configured. You cannot remove, activate, deactivate or move the default bandwidth management policy. Figure 215 Configuration > Bandwidth Management UAG715 User's Guide 311
