R0106-HP MSR Router Series ACL and QoS Command Reference(V7)

Usage guidelines

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 fails.

You can edit ACL rules only when the match order is config.

• If you do not specify any optional keywords, the undo rule command deletes the entire rule.

• If you specify optional keywords or arguments, the undo rule command deletes the specified

attributes.

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

Examples

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

<Sysname> system-view

[Sysname] acl number 4000

[Sysname-acl-ethernetframe-4000] rule permit type 0806 ffff

[Sysname-acl-ethernetframe-4000] rule deny type 8035 ffff
