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: Protocol carried by IPv4. It can be a number in the range of 0 to 255, or in words, gre (47), icmp (1), igmp (2), ip, ipinip (4), ospf (89), tcp (6), or udp (17). Table 6 describes the parameters that you can specify regardless of the value that the protocol argument takes. 18

IPv4 advanced ACL view
Default level
2: System level
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
: Protocol carried by IPv4. It can be a number in the range of 0 to 255, or in words,
gre
(47),
icmp
(1),
igmp
(2),
ip
,
ipinip
(4),
ospf
(89),
tcp
(6), or
udp
(17).
Table 6
describes the parameters that you
can specify regardless of the value that the
protocol
argument takes.
