deny — configures a MAC ACL filter to drop packets.
seq — configure a MAC ACL filter with a specified sequence number.
seq
Configure a filter with a specific sequence number.
Syntax
seq sequence-number {deny | permit} {any | host mac-address |
mac-source-address mac-source-address-mask} {any | host mac-
address
| mac-destination-address mac-destination-address-mask}
[ethertype operator] [count [byte]] [log] [monitor]
To delete a filter, use the no seq sequence-number command.
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.
