R21xx-HP FlexFabric 11900 ACL and QoS Command Reference

Parameters

rule-id: Specifies a rule ID in the range of 0 to 65534. If no rule ID is specified 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.

cos vlan-pri: Matches an 802.1p priority. The vlan-pri argument can be a number in the range of 0 to 7,

or in words, best-effort (0), background (1) , spare (2), excellent-effort (3), controlled-load (4), video (5),

voice (6), or network-management (7).

counting: Counts the number of times the Ethernet frame header ACL rule has been matched. The

counting keyword enables match counting specific to rules, and the hardware-count keyword in the

packet-filter command enables match counting for all rules in an ACL. If the counting keyword is not

specified, matches for the rule are not counted.

dest-mac dest-address dest-mask: Matches a destination MAC address range. The dest-address and

dest-mask arguments represent a destination MAC address and mask in the H-H-H format.

lsap lsap-type lsap-type-mask: Matches the DSAP and SSAP fields in LLC encapsulation. The lsap-type

argument is a 16-bit hexadecimal number that represents the encapsulation format. The lsap-type-mask

argument is a 16-bit hexadecimal number that represents the LSAP mask.

type protocol-type protocol-type-mask: Matches one or more protocols in the Ethernet frame header. The

protocol-type argument is a 16-bit hexadecimal number that represents a protocol type in Ethernet_II and

Ethernet_SNAP frames. The protocol-type-mask argument is a 16-bit hexadecimal number that represents

a protocol type mask.

source-mac source-address source-mask: Matches a source MAC address range. The source-address

argument represents a source MAC address, and the sour-mask argument represents a mask in the H-H-H

format.

time-range time-range-name: Specifies a time range for the rule. The time-range-name argument is a

case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not

configured, the system creates the rule. However, the rule using the time range can take effect only after

you configure the timer range. For more information about time range, see ACL and QoS Configuration

Guide

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 no optional keywords are provided for the

undo rule command, you delete the entire rule. If optional keywords or arguments are provided, you

delete the specified attributes.

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

If an Ethernet frame header ACL is for QoS traffic classification or packet filtering, to use the lsap keyword,

the lsap-type argument must be AAAA, and the lasp-type-mask argument must be FFFF. Otherwise, the

ACL cannot be function correctly.

Examples

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