Parameters
  • 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) Enter the keyword any to specify any source or destination IP address.
    NOTE: The control-plane ACLs do not support the any parameter.
  • host ip-address — (Optional) Enter the IPv4 address to use a host address only.
  • ack — (Optional) Set the bit as acknowledgement.
  • fin — (Optional) Set the bit as finish—no more data from sender.

  • byte — (Optional) Count bytes the filter processes.
  • dscp value — (Optional) Permit a packet based on the DSCP values, 0 to 63.
  • fragment — (Optional) Use ACLs to control packet fragments.
  • log — (Optional) Enables ACL logging. Information about packets that match an ACL rule are logged.
  • operator — (Optional) Enter a logical operator to match the packets on the specified port number. The following options are available:
    • eq — Equal to
    • gt — Greater than
    • lt — Lesser than
    • neq — Not equal to
