Syntax
seq sequence-number deny tcp [A.B.C.D | A.B.C.D/x | any | host ip-address
[operator]] [[A.B.C.D | A.B.C.D/x | any | host ip-address [operator] ] [ack |
fin | psh | rst | syn | urg] [capture | dscp value | fragment]
Parameters
• sequence-number — Enter the sequence number to identify the route-map for editing and sequencing
number, from 1 to 16777214.
• A.B.C.D — Enter the IPv4 address in dotted decimal format.
• A.B.C.D/x — Enter the number of bits that must match the dotted decimal address.
• any — (Optional) Set all routes which are subject to the lter:
– capture — (Optional) Capture packets the lter processes.
– dscp value — (Optional) Deny a packet based on the DSCP values, from 0 to 63.
– fragment — (Optional) Use ACLs to control packet fragments.
– ack — (Optional) Set the bit as acknowledgement.
– fin — (Optional) Set the bit as nish—no more data from sender.
– psh — (Optional) Set the bit as push.
– rst — (Optional) Set the bit as reset.
– syn — (Optional) Set the bit as synchronize.
– urg — (Optional) Set the bit set as urgent.
• operator — (Optional) Enter a logical operator to match the packets on the specied port number. The
following options are available:
– eq — Equal to
– gt — Greater than
– lt — Lesser than
– neq — Not equal to
– range — Range of ports, including the specied port numbers.
• host ip-address — (Optional) Enter the IPv4 address to use a host address only.
Default
Not congured
Command Mode IPV4-ACL
Usage Information The no version of this command removes the lter, or use the no seq sequence-number command if you
know the lter’s sequence number.
