Defining TOS filters
To specify the QoS for all packets that match a specific filter specification, you can define a
TOS filter locally in a Filter profile, and then apply the filter to any number of Connection
profiles or RADIUS profiles. (The Filter-ID attribute can apply a local Filter profile to
RADIUS user profiles.) Administrators can also define TOS filters directly in a RADIUS user
profile by setting the Ascend-Filter attribute.
Examples of connection-based TOS configuration
The parameter settings in this example enable TOS for incoming packets on a WAN interface.
The profile sets the priority of the packets at 6, which specifies that an upstream router that
supports priority queuing will not drop the packets until it has dropped all packets of a lower
priority. The values shown set TOS to prefer maximum throughput, which specifies that an
upstream router that supports priority queuing will choose a high bandwidth connection if one
is available, even if it has higher cost or higher latency or is less reliable than another available
link.
