Parameters
rule-id: Specifies a rule ID in the range of 0 to 65534. If no rule ID is provided when you create an ACL
rule, the system automatically assigns it a rule ID. This rule ID takes the nearest higher multiple of the
numbering step to the current highest rule ID, starting from 0. For example, if the rule numbering step is
5 and the current highest rule ID is 28, the rule is numbered 30.
deny: Denies matching packets.
permit: Allows matching packets to pass.
protocol: Specifies a protocol number in the range of 0 to 255, or specifies a protocol by its name, gre
(47), icmp (1) , igmp (2), ip, ipinip (4), ospf (89), tcp (6), or udp (17) . The ip keyword specifies all
protocols. Table 6 de
scribes the parameters that you can specify regardless of the value that the protocol
argument takes.
