To do… Use the command… Remarks

Create an Ethernet frame
header ACL and enter its view
acl number acl-number [ name
acl-name ] [ match-order
{ auto | config } ]

config.
If you specify a name for an
ACL when creating the ACL,
you can use the acl name
acl-name command to enter
the view of the ACL later.
Create or modify a rule
rule [ rule-id ] { deny | permit }
[ cos vlan-pri | dest-mac
dest-addr dest-mask | { lsap
lsap-type lsap-type-mask | type
protocol-type
protocol-type-mask } |
source-mac sour-addr

Configure a description for the
Ethernet frame header ACL

header ACL has no ACL
description.
Configure a rule description
rule rule-id comment text
Optional
By default, an Ethernet frame

Note that:
z You can only modify the existing rules of an ACL that uses the match order of config. When
modifying a rule of such an ACL, you may choose to change just some of the settings, in which
case the other settings remain the same.
z You cannot create a rule with, or modify a rule to have, the same permit/deny statement as an
existing rule in the ACL.
z When the ACL match order is auto, a newly created rule will be inserted among the existing rules in
the depth-first match order. Note that the IDs of the rules still remain the same.
