Revision P4
In the VoIP example above, filter pattern 1 includes only traffic from the VoIP computer.
This is done by setting the filter pattern to include the source IP address of the VoIP traffic
and a source IP netmask of 255.255.255.255. The destination IP address and netmask
should be set to 0.0.0.0 (traffic is not filtered by destination IP address). Filter pattern 1 is
then assigned to the high priority queue.
Filter pattern 2 includes all other traffic. This is done by assigning all IP addresses and
masks a value 0.0.0.0 (traffic is not filtered by source or destination IP address). Filter pat-
tern 2 is then assigned to the low priority queue.
The table below describes the parameters in the filter pattern table entries.
Table 5:
Parameter
Description
IP Source Address
The source IP address segment that will be allowed by the filter. A
mask value 0.0.0.0 indicates that traffic is not filtered by IP source
address. A mask value 255.255.255.255 indicates that only traffic from
the IP source address is allowed by the filter.
IP Source Mask
IP Destination
Address
The destination IP address segment that will be allowed by the filter. A
mask value 0.0.0.0 indicates that traffic is not filtered by IP destination
address. A mask value 255.255.255.255 indicates that only traffic from
the IP destination address is allowed by the filter.
IP Destination Mask
IP Protocol Type
The IP protocol type range that will be allowed by the filter. A mask
value of 0x00 indicates that traffic is not filtered by protocl type. A
mask value of 0xFF indicates that only traffic from this protocol type is
allowed by the filter
IP Protocol Type
Mask
IP TOS Field
The IP Type Of Service range that will be allowed by the filter. A mask
value of 0x00 indicates that traffic is not filtered by type of service. A
mask value of 0xFF indicates that only traffic from this type of service
is allowed by the filter.
IP TOS Field Mask
TCP/UDP Source
Port Number
The TCP/UDP Source Port Number range that will be allowed by the
filter. A mask value of 0x00 indicates that traffic is not filtered by TCP/
UDP source port. A mask value of 0xFF indicates that only traffic from
this TCP/UDP source port number is allowed by the filter
TCP/UDP Source
Port Number Mask
TCP/UDP Destina-
tion Port Number
The TCP/UDP Destination Port Number range that will be allowed by
the filter. A mask value of 0x00 indicates that traffic is not filtered by
TCP/UDP destination port. A mask value of 0xFF indicates that only
traffic from this TCP/UDP destination port number is allowed by the
filter

tion Port Number

Filter Pattern Sit
Queue Table Entry
Number
Assign the filter pattern to a queue table entry previously defined (see
section 2.4.1
above).
Filter Pattern Status
"Not in Service" indicates that the filter pattern has been disabled.
"Active" means that the filter pattern is operational.
