Parameters • Use the no permit tcp {source mask | any | host ip-address} {destination mask | any | host ip-address} command. source mask any host ip-address bit dscp operator port port destination mask Enter the IP address of the network or host from which the packets were sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or noncontiguous. Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host and then enter the IP address to specify a host IP address. Enter a flag or combination of bits: • ack: acknowledgement field • fin: finish (no more data from the user) • psh: push function • rst: reset the connection • syn: synchronize sequence numbers • urg: urgent field Enter the keyword dscp to deny a packet based on the DSCP value. The range is 0 to 63. (OPTIONAL) Enter one of the following logical operand: • eq = equal to • neq = not equal to • gt = greater than • lt = less than • range = inclusive range of ports (you must specify two ports for the port parameter) Enter the application layer port number. Enter two port numbers if you are using the range logical operand. The range is 0 to 65535. The following list includes some common TCP port numbers: • 23 = Telnet • 20 and 21 = FTP • 25 = SMTP • 169 = SNMP Enter the IP address of the network or host to which the packets are sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or noncontiguous. 249
