36.7 Enabling MAC Filtering

You can create a filter to drop packets based on the MAC address of the source or the
destination.

Syntax:

mac-filter name mac vlan drop dst/both>

=

Specifies the network IP address of the final destination.

=

Specifies the subnet mask of this destination.

=

Specifies the IP address of the gateway. The gateway is an
immediate neighbor of your switch that will forward the
packet to the destination. The gateway must be a router on
the same segment as your switch.

[metric ]

=

The metric represents the “cost” of transmission for routing
purposes. IP routing uses hop count as the measurement of
cost, with a minimum of 1 for directly connected networks.
Enter a number that approximates the cost for this link. The
number need not be precise, but it must be between 1 and
15. In practice, 2 or 3 is usually a good number.

[name ]

=

Specifies a descriptive name (up to 32 printable ASCII
characters) for identification purposes.

[inactive]

=

Deactivates a static route
