Information
The order option is relevant in the context of the Policy QoS feature only. See the “Quality of
Service” chapter of the FTOS Configuration Guide for more information.
When you use the log option, CP processor logs details about the packets that match. Depending on
how many packets match the log entry and at what rate, the CP may become busy as it has to log these
packets’ details.
The monitor option is relevant in the context of flow-based monitoring only. See the Chapter 44, Port
Monitoring .
You cannot include IP, TCP or UDP filters in an ACL configured with ARP filters.
permit ether-type
e
Configure a filter that allows traffic with specified types of Ethernet packets. This command is
supported only on 12-port GE line cards with SFP optics; refer to your line card documentation for
specifications.
Syntax permit ether-type protocol-type-number

To remove this filter, use one of the following:
• Use the
no seq sequence-number
command syntax if you know the filter’s sequence number
or
• Use the
no permit ether-type protocol-type-number
{
destination-mac-address
mac-address-mask
|
any
}
vlan vlan-id
{
source-mac-address mac-address-mask
|

command.
Parameters
Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.
Version 8.1.1.0 Introduced on E-Series ExaScale
Version 7.4.1.0
Added support for non-contiguous mask and added the
monitor
option.
Version 6.5.10
Expanded to include the optional QoS
order
priority for the ACL entry.
Note:
When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.
protocol-type-number Enter a number from 600 to FFF as the specific Ethernet type traffic to drop.
destination-mac-address
mac-address-mask Enter a MAC address and mask in the nn:nn:nn:nn:nn format.
For the MAC address mask, specify which bits in the MAC address must
match.
The MAC ACL supports an inverse mask, therefore, a mask of ff:ff:ff:ff:ff:ff
allows entries that do not match and a mask of 00:00:00:00:00:00 only allows
entries that match exactly.
any
Enter the keyword
any
to match and drop specific Ethernet traffic on the
interface.
