deny (MAC)

Use the deny command in MAC Access List Configuration mode to set deny

conditions (ACEs) for a MAC ACL.

{any | source source-wildcard} {any | destination destination-wildcard}

[{eth-type 0}| aarp | amber | dec-spanning | decnet-iv | diagnostic | dsm |

etype-6000] [vlan vlan-id] [cos cos cos-wildcard] [time-range time-range-name]

[disable-port | log-input]

source—Source MAC address of the packet.

source-wildcard—Wildcard bits to be applied to the source MAC address.

Use ones in the bit position that you want to be ignored.

destination—Destination MAC address of the packet.

destination-wildcard—Wildcard bits to be applied to the destination MAC

address. Use 1s in the bit position that you want to be ignored.

eth-type—The Ethernet type in hexadecimal format of the packet.

vlan-id—The VLAN ID of the packet. (Range: 1–4094)

cos—The Class of Service of the packet.(Range: 0–7)

cos-wildcard—Wildcard bits to be applied to the CoS.

time-range-name—Name of the time range that applies to this permit

statement.(Range: 1–32)

disable-port—The Ethernet interface is disabled if the condition is matched.

log-input—Sends an informational syslog message about the packet that

matches the entry. Because forwarding is done in hardware and logging is

done in software, if a large number of packets match a deny ACE containing

a log-input keyword, the software might not be able to match the hardware

processing rate, and not all packets will be logged.

Default Configuration

No MAC access list is defined.
