[syn] [time-range name] [urg] 

(Optional) Define a TCP access list and the access conditions. 

Enter tcp for Transmission Control Protocol. The parameters are the same as 
those described in Step 3a, with these additional optional parameters: 

ack—Acknowledgment bit set.

established—An established connection. A match occurs if the TCP 
datagram has the ACK or RST bits set. 

fin—Finished bit set; no more data from sender.

neq {port | protocol}—Matches only packets that are not on a given port 
number.

psh—Push function bit set.

range {port | protocol}—Matches only packets in the port number range.

rst—Reset bit set.

syn—Synchronize bit set.

urg—Urgent pointer bit set.

(Optional) Define a UDP access list and the access conditions.

Enter udp for the User Datagram Protocol. The UDP parameters are the same as 
those described for TCP, except that the [operator [port]] port number or name 
must be a UDP port number or name, and the established parameter is not valid 
for UDP.

(Optional) Define an ICMP access list and the access conditions.

Enter icmp for Internet Control Message Protocol. The ICMP parameters are the 
same as those described for most IP protocols in Step 3a, with the addition of the 
ICMP message type and code parameters. These optional keywords have these 
meanings:

icmp-type—Enter to filter by ICMP message type, a number from 0 to 255.

icmp-code—Enter to filter ICMP packets that are filtered by the ICMP 
message code type, a number from 0 to 255.

icmp-message—Enter to filter ICMP packets by the ICMP message type 
name or the ICMP message type and code name. To see a list of ICMP 
message type names and code names, use the ? key or see command 
reference for this release.

Return to privileged EXEC mode.
