bits are ignored.
• Destination — Destination MAC Address.
— MAC Address — Matches the destination MAC Address to which packets are
addressed to the rule.

used to mask all or part of a destination MAC address. Wildcard masks specify
which bits are used and which are ignored. A wildcard mask of FF:FF:FF:FF:FF
indicates that no bit is important. A wildcard mask of 00.00.00.00.00.00
indicates that all bits are important. For example, if the destination MAC
address is E0:00:AB:22:11:33:00 and the wildcard mask is 00:00:00:00:00:FF,
the last two bits are ignored.

— Shutdown — Drops packet that meet the ACL criteria, and disables the port to
which the packet was addressed. Ports are reactivated from the Port
