Nortel Business Secure Router 252 Configuration — Basics
Configuring class setup
The class setup screen displays the configured bandwidth classes by individual
interface. Select an interface and click the buttons to perform the actions
described next. Click + to expand the class tree or click - to collapse the class tree.
Each interface has a permanent root class. The bandwidth budget of the root class
is equal to the speed you configured on the interface (see “Configuring summary”
on page 302 to configure the speed of the interface). Configure subclass layers for
the root class.
To add or delete child classes on an interface, click BW MGMT, then the Class
Setup tab. The screen appears as shown in Figure 99.
Speed (kbps) Enter the amount of bandwidth for this interface that you want to allocate
using bandwidth management.
This appears as the bandwidth budget of the interface root class (see
“Configuring class setup” on page 303). Nortel recommends that you set
this speed to match what the device connected to the port can handle.
For example, set the WAN interface speed to 1 000 kb/s (or less) if the
broadband device connected to the WAN port has an upstream speed of
1 000 kb/s.
