Configure a filter with a specific sequence number.
Syntax
seq

{deny | permit} {any | host
mac-address

mac-source-address mac-source-address-mask
} {any | host
mac-

] [count [byte]]
Parameters
sequence-
number
Enter a number as the filter sequence number. The range is
from zero (0) to 65535.
deny
Enter the keyword
deny
to drop any traffic matching this
filter.
permit
Enter the keyword
permit
to forward any traffic matching
this filter.
any
Enter the keyword
any
to filter all packets.
host
mac-
address
Enter the keyword
host
and then enter a MAC address to
filter packets with that host address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
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.
mac-source-
address-mask
Specify which bits in the MAC address must be matched.
mac-
destination-
address
Enter the destination MAC address and mask in
nn:nn:nn:nn:nn:nn format.
mac-
destination-
address-mask
Specify which bits in the MAC address must be matched.
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.
ethertype
operator
(OPTIONAL) To filter based on protocol type, enter one of
the following Ethertypes:
•
ev2
- is the Ethernet II frame format.
•
llc
- is the IEEE 802.3 frame format.
•
snap
- is the IEEE 802.3 SNAP frame format.
count
(OPTIONAL) Enter the keyword
count
to count packets the
filter processes.
byte
(OPTIONAL) Enter the keyword
byte
to count bytes the filter
processes.
