Observe this guideline when using these criteria:
The Protocol variable must be left blank or set to IP.
TCP Source Ports (Layer 4)
TCP Destination Ports (Layer 4)
A traffic flow can be identified by a source and/or destination TCP port
number contained within the header of an IP frame. Observe the following
guidelines when using these criteria:
The Protocol variable must be left blank or set to IP.
The IP Protocol variable must be left blank or set to TCP.
A classifier cannot contain criteria for both TCP and UDP ports. You
may specify one in a classifier, but not both.
UDP Source Ports (Layer 4)
UDP Destination Ports (Layer 4)
A traffic flow can be identified by a source and/or destination UDP port
number contained within the header of an IP frame. Observe the following
guidelines when using these criteria:
The Protocol variable must be left blank or set to IP.
The IP Protocol variable must be left blank or set to UDP.
A classifier cannot contain criteria for both TCP and UDP ports. You
may specify only one in a classifier.
TCP Flags
A traffic flow can be based on the following TCP flags:
URG - Urgent
ACK - Acknowledgement
RST - Reset
PSH - Push
SYN - Synchronization
FIN - Finish
Observe the following guidelines when using this criterion:
The Protocol variable must be left blank or set to IP.
The IP Protocol variable must be left blank or set to TCP.
A classifier cannot contain both a TCP flag and a UDP source and/or
destination port.
