command puts the switch in the extended MAC access-list configuration mode.

• Source MAC address
• Destination MAC address
• EtherType
You can apply named MAC extended ACLs to VLANs and to Layer 2 interfaces.
Usage Guidelines Standard and extended MAC ACLs cannot share the same name.
Enter no mac access-list extended to remove the access list.
Examples To create a MAC extended ACL named mac1:
switch(config)# mac access-list extended mac1
switch(conf-macl-ext)#

switch(conf-macl-ext)# no mac access-list extended mac1
switch(config)#
