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.
Parameter
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
IP Source Mask
the IP source address is allowed by the filter.
IP Destination
The destination IP address segment that will be allowed by the filter. A
Address
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
IP Destination Mask
the IP destination address is allowed by the filter.
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
IP Protocol Type
mask value of 0xFF indicates that only traffic from this protocol type is
Mask
allowed by the filter
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
IP TOS Field Mask
is allowed by the filter.
TCP/UDP Source
The TCP/UDP Source Port Number range that will be allowed by the
Port Number
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
TCP/UDP Source
this TCP/UDP source port number is allowed by the filter
Port Number Mask
TCP/UDP Destina-
The TCP/UDP Destination Port Number range that will be allowed by
tion Port Number
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
TCP/UDP Destina-
traffic from this TCP/UDP destination port number is allowed by the
tion Port Number
filter
Mask
Filter Pattern Sit
Assign the filter pattern to a queue table entry previously defined (see
Queue Table Entry
section 2.4.1
Number
"Not in Service" indicates that the filter pattern has been disabled.
Filter Pattern Status
"Active" means that the filter pattern is operational.
