Usage
Information
The number of entries allowed per ACL is hardware-dependent. For detailed specifications on entries
allowed per ACL, refer to your line card documentation.
If you configure an extended MAC ACL to be used only to filter protocol traffic for CoPP, you must enter
the keyword cpu-qos.
Use this command in Configuration Terminal Batch mode to configure an extended MAC access control
list in a dual-homing setup.
Example
Dell(conf)#mac-access-list access-list extended TestMATExt
Dell(config-ext-macl)#remark 5 IPv4
Dell(config-ext-macl)#seq 10 permit any any ev2 eq 800 count bytes
Dell(config-ext-macl)#remark 15 ARP
Dell(config-ext-macl)#seq 20 permit any any ev2 eq 806 count bytes
Dell(config-ext-macl)#remark 25 IPv6
Dell(config-ext-macl)#seq 30 permit any any ev2 eq 86dd count bytes
Dell(config-ext-macl)#seq 40 permit any any count bytes
Dell(config-ext-macl)#exit
Dell(conf)#do show mac accounting access-list snickers interface te 0/47
in

Commands
mac access-list standard — configures a standard MAC access list.
show mac accounting access-list — displays MAC access list configurations and counters (if configured).
permit
To pass packets matching the criteria specified, configure a filter.
C9000 Series
Syntax
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 [interval minutes]
[threshold-in-msgs [count]] [monitor]
To remove this filter, you have two choices:
● Use the no seq sequence-number command if you know the filter’s sequence number.
● Use the no permit {any | host mac-address | mac-source-address mac-source-
address-mask} {any | mac-destination-address mac-destination-address-
mask} command.
Parameters
any Enter the keyword any to forward all packets.
host Enter the keyword host then a MAC address to forward packets with that host
address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
mac-source-
address-mask
(OPTIONAL) 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.
