■ Network-wide Configuration — applies the selected configuration
to all of the supported 3Com devices in the current inventory file.
3Com recommends that you use this configuration type whenever
you intend to make changes to your selection or when you are first
configuring traffic prioritization on your network. If a new
configuration is not applied across all of the devices then end-to-end
traffic prioritization may not be possible.
■ Device Type Configuration — applies the selected configuration to
all of the devices of a specific type in the current inventory file. 3Com
recommends that you only use this configuration type when you have
added a large number of devices of a particular type to your network
and you wish to configure them to participate in a previously
configured end-to-end traffic prioritization.
■ Custom Configuration — allows you to choose which of the
supported 3Com devices in your network that the wizard should apply
the selected configuration to. 3Com recommends that you only use
this configuration type when you have added new devices to your
network and you wish to configure them to participate in a previously
configured end-to-end traffic prioritization.
Servers Step
You can select servers for prioritization or blocking. In terms of the
Prioritize Network Traffic Wizard, a server can be any device with an IP
address regardless of whether or not the device is present in the 3Com
Network Administrator inventory file. This enables you to perform actions
such as blocking traffic to and from streaming media servers that are
external to your company or to prioritize traffic to and from your partners
websites.
■ Prioritized Servers — when a server is prioritized, two things occur:
■ Traffic to or from the prioritized server will be treated as more
important than non-prioritized traffic by the configured devices.
Traffic will, therefore, flow through the network faster and with
less chance of being dropped.
■ Prioritizing the server overrides application blocking, so a server
selected for prioritization will still be able to use applications that
are selected for blocking without the devices in the network
dropping the application’s traffic.
