MAC_ADDRESS] [EtherType | arp | fcoe | ipv4]}
Operands any Specifies any source MAC address.
host MAC_ADDRESS
Specifies the source host MAC address for which to set permit conditions.

Examples To create a rule in a MAC extended ACL to permit IPv4 traffic from the source MAC address
0022.3333.4444
to the destination MAC address 0022.3333.5555 and to enable the counting
of packets:
