R3166-R3206-HP High-End Firewalls Access Control Command Reference-6PW101

Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating

or editing has the same deny or permit statement as another rule in the ACL, your creation or editing

attempt will fail.

To view rules in an ACL and their rule IDs, use the display acl all command.

Related commands: acl, display acl, step, and time-range.

Examples

# Create a rule in ACL 4000 to permit ARP packets and deny RARP packets.

Parameters

rule-id: Specifies a rule ID, which ranges from 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 0 to 255, or in words, gre (47), icmp

(1) , igmp (2), ip, ipinip (4), ospf (89), tcp (6), or udp (17) . Table 3 de

scribes the parameters that you can

specify regardless of the value that the protocol argument takes.
