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):
Input filters...
In filter NN
Type=TOS
IPTOS...
Src Mask=0.0.0.0
Src Adrs=0.0.0.0
Dst Mask=0.0.0.0
Dst Adrs=0.0.0.0
Protocol=0
Src Port Comp=None
Src Port #=0
Dst Port Cmp=None
Dst Port #=0
Precendence=000
Type of Service=Normal
Parameter Specifies
Src Mask A mask to be applied to the Src Adrs value before comparing that
value to the source address of a packet.
Src Adrs 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.
Dst Mask A mask to be applied to the Dst Adrs value before comparing that
value to the destination address of a packet.
Dst Adrs 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.
Protocol 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.
Src Port Cmp 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
packets source port number is Less (less than), Eql (equal to), Gtr
(greater than), or Neq (not equal to) the Src Port # value.
