Defining Type of Service filters
Defining Type of Service filters
To enable proxy-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. For TOS filters, the forwarding action in the filter
has no effect.
Settings in a local Filter profile
Following are the relevant Filter parameters (shown with their default settings):

Specifies
A mask to be applied to the Src Adrs value before comparing that
value to the source address of a packet.
An IP address. After applying the Src Mask value, the MAX unit
compares the result to the source address in a packet. For details,
see "Filtering by source or destination address" on page 15-14.
A mask to be applied to the Dst Adrs value before comparing that
value to the destination address of a packet.
An IP address. After applying the Dst Mask value, the MAX unit
compares the result to the source address in a packet.For details,
see "Filtering by source or destination address" on page 15-14.
A protocol number. A value of zero matches all protocols. If you
specify a nonzero number, the MAX unit compares it to the
Protocol field in each packet. For list of protocol numbers, see
RFC 1700.
Type of comparison to perform when comparing source port
numbers. With a setting of None (the default), no comparison is
made. You can specify that the filter matches the packet if the
packet's source port number is Less (less than), Eql (equal to), Gtr
(greater than), or Neq (not equal to) the Src Port # value.
