Cisco ASA Series CLI Configuration Guide
Chapter 1 Adding an EtherType Access List
Configuring EtherType Access Lists
Step 1
Create an access list by adding an ACE and applying an access list name, as shown in the
EtherType Access Lists” section on page 1-3
Step 2
Apply the access list to an interface. (See the
“Configuring Access Rules” section on page 1-7
for more
information.)
Adding EtherType Access Lists
To configure an access list that controls traffic based upon its EtherType, perform the following steps:
Detailed Steps
Command
Purpose
access-list
access_list_name
ethertype
{
deny
|
permit
}
{
ipx
|
bpdu
|
mpls-unicast
|
mpls-multicast
|
any
|
hex_number
}
Example:
hostname(config)# hostname(config)#
access-list ETHER ethertype permit ipx
Adds an EtherType ACE.
The
access_list_name
argument lists the name or number of an access list.
When you specify an access list name, the ACE is added to the end of the
access list. Enter the
access_list_name
in upper case letters so that the
name is easy to see in the configuration. You might want to name the access
list for the interface (for example, INSIDE) or for the purpose (for
example, MPLS or PIX).
The
permit
keyword permits access if the conditions are matched.
deny
denies access.
The
ipx
keyword specifies access to IPX.
The
bpdu
keyword specifies access to bridge protocol data units, which are
allowed by default.
The
deny
keyword denies access if the conditions are matched. If an
EtherType access list is configured to deny all, all ethernet frames are
discarded. Only physical protocol traffic, such as auto-negotiation, is still
allowed.
The
mpls-multicast
keyword specifies access to MPLS multicast.
The
mpls-unicast
keyword specifies access to MPLS unicast.
The
any
keyword specifies access to any traffic.
The
hex_number
argument indicates any EtherType that can be identified
by a 16-bit hexadecimal number greater than or equal to 0x600. (See RFC
1700, “Assigned Numbers,” at http://www.ietf.org/rfc/rfc1700.txt for a list
of EtherTypes.)
Note
To remove an EtherType ACE, enter the
no
access-list
command
with the entire command syntax string as it appears in the
configuration.
