Src Port #

A port number to be compared with the source port of a packet. 
TCP and UDP port numbers are typically assigned to services. For 
more details, see “Filtering by port numbers” on page 15-14.

Dst Port Cmp

Type of comparison to perform when comparing destination 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 destination port number is Less (less than), Eql (equal to), 
Gtr (greater than), or Neq (not equal to) the Dest Port # value.

Dest Port #

A port number to be compared with the destination port of a 
packet. TCP and UDP port numbers are typically assigned to 
services. For more details, see “Filtering by port numbers” on 
page 15-14.

Precedence

Priority level of the data stream. The three most significant bits of 
the TOS byte are priority bits used to set precedence for priority 
queuing. When TOS is enabled and the packet matches the filter, 
the bits can be set to one of the following values (most significant 
bit first):

•

000—Normal priority

•

001—Priority level 1

•

010—Priority level 2

•

011—Priority level 3

•

100—Priority level 4

•

101—Priority level 5

•

110—Priority level 6

•

111—Priority level 7 (the highest priority)

Type of Service

Type of Service of the data stream. The value of this attribute sets 
the four bits following the three most significant bits of TOS byte. 
The next four bits of the TOS byte are used to choose a link 
according to the type of service. When TOS is enabled and the 
packet matches the filter, one of the following values can be set in 
the packet:

Normal—Normal service

Cost—Minimize monetary cost

Reliability—Maximize reliability

Throughput—Maximize throughput

Latency—Minimize delay.
