Usage Guidelines
• Use the no form of this command to remove established from a condition; however, at least one classi-
fication parameter must be associated with a condition.
• When an initial TCP connection packet is received only the syn flag is set. As a result, TCP packets are 
only examined if they are not the starting packet.
• Typically this condition is used in combination with source ip, destination ipsource portdestina-
tion portsource TCP port, or destination TCP port conditions. 
• The source macdestination mac, and ethertype conditions cannot be combined with the estab-
lished condition parameter.
• Note that even though established can be used with most action parameters, it is mainly intended for 
ACL use. 
Examples
-> policy condition cond2 source ip 192.168.5.10 established
-> policy condition cond3 destination ip 10.255.11.40
