CHAPTER 31
Bandwidth Management
31.1 Bandwidth Management Overview
Bandwidth management provides a convenient way to manage the use of various services on the
network. It manages general protocols (for example, HTTP and FTP) and applies traffic prioritization
to enhance the performance of delay-sensitive applications like voice and video.
31.1.1 BWM Type
The ZyWALL / USG supports two types of bandwidth management: shared, per-user and per-
source-ip.
The shared BWM type is selected by default in a bandwidth management rule. All users to which
the rule is applied need to share the bandwidth configured in the rule. If the BWM type is set to
per-user in a rule, every user that matches the rule can use up to the configured bandwidth by
his/her own. Set the BWM type set to per-source-ip in a rule,when you want to set the maximum
bandwidth for traffic from an individual source IP address.
31.2 Bandwidth Management Commands
The following table lists the bwm commands. You must use the configure terminal command to
enter the configuration mode before you can use these commands.
Table 115 bwm Commands
COMMAND DESCRIPTION
bwm <1..127> Enters the config-bwm sub-command mode to configure a bandwidth
management policy. See Table 116 on page 210 for the sub-commands.
[no] bwm activate Enables bandwidth management on the ZyWALL / USG.
The no command disabled bandwidth management.
bwm append Enters the config-bwm sub-command mode to add a policy to the end of the

bwm default inbound priority <1..7> Specifies a number between 1 and 7 to set the priority for incoming traffic

The smaller the number, the higher the priority. Traffic with a higher priority
is given bandwidth before traffic with a lower priority.

that matches the default policy.
bwm delete <1..127> Removes a policy.
