ATM
The ATM menu allows the user to adjust ATM Quality of Service (QoS) or traffic parameters to suit
specific traffic requirements. For applications or circumstances where packet loss or packet delay
are a concern, ATM QoS can be adjusted to minimize problems. For most accounts, it will not be
necessary to change these settings. Altering QoS settings can adversely affect performance of
some commonly used Internet applications.
If you plan to change QoS or traffic parameters, contact your ISP or network services provider for
information on what types of adjustment are available or possible for your account. Your ISP may
not support the class of service you want to use.
The ATM menu is also used to enable IGMP forwarding (IGMP Proxy).
ATM Virtual Circuit configuration menu
To set new QoS parameters, use the PVC drop-down menu to select the connection you want to
configure. Select the Service Category and type in the allowable bandwidth settings. Click the
Apply button to put the new settings into effect, remember to save the new settings and reboot
the Router.
See the table below for a description of the traffic and QoS parameters.
