Description

Creates or modifies a MAC traffic class to match specified packets. Class is composed of one or more class entries ordered and prioritized by sequence numbers. With this command, each class can classify traffic based on MAC header information.

The no form of the command can be used to delete either a MAC traffic class (use no with the class command) or an individual MAC traffic class entry (use no with the sequence number).

Command context

config

The class mac <CLASS-NAME> command takes you into the config-class-mac context where you enter the class entries.

Parameters

mac

Specifies create or modify a MAC class.

<CLASS-NAME>

Specifies the name of this class.

<SEQUENCE-NUMBER>

Specifies a sequence number for the class entry. Optional. Range: 1-4294967295.

{match|ignore}

Creates a rule to match or ignore specified packets.

comment

Stores the remaining entered text as a class comment.

{any|<SRC-MAC-ADDRESS>[/<ETHERNET-MASK>}]}

Specifies the source host MAC address (xxxx.xxxx.xxxx), OUI, or the keyword any. You can optionally include the following:

<ETHERNET-MASK> - The address bits to mask (xxxx.xxxx.xxxx).

{any|<DST-MAC-ADDRESS>[/<ETHERNET-MASK>}]}

Specifies the destination host MAC address (xxxx.xxxx.xxxx), OUI, or the keyword any. You can optionally include the following:

<ETHERNET-MASK> - The address bits to mask (xxxx.xxxx.xxxx).

Protocol

Select an ethertype protocol from the following (enter one only):

any - Any ethertype protocol
<NUMBERIC-ETHERTYPE> - Enter an EtherType protocol number. Range: 0x600-0xffff.
Or enter an EtherType protocol name from the following list:

- wake-on-lan

pcp <PCP-VALUE>

Specifies matching on QoS Priority Code Point. Range: 0-7.

vlan <VLAN-ID>

Specifies matching on a VLAN ID. Enter a VLAN ID or the VLAN name, if configured.

count

Keeps the hit counts of the number of packets matching this class entry.
