This example adds a permanent entry to the FDB:

create fdbentry 00:E0:2B:12:34:56 vlan marketing port 3:4

The permanent entry has the following characteristics:

• MAC address is 00E02B123456.

• VLAN name is marketing.

• Slot number for this device is 3.

• Port number for this device is 4.

This example associates the QoS profile qp2 with a dynamic entry that will be learned

by the FDB:

create fdbentry 00:A0:23:12:34:56 vlan net34 dynamic qosprofile qp2

This entry has the following characteristics:

• MAC address is 00A023123456.

• VLAN name is net34.

• The entry will be learned dynamically.

• QoS profile qp2 will be applied when the entry is learned.

config fdb agingtime <number> Configures the FDB aging time. The range is 15

through 1,000,000 seconds. The default value is

300 seconds. A value of 0 indicates that the entry

should never be aged out.

enable learning port <slot:portlist> Enables MAC address learning on one or more

ports.

disable learning port <slot:portlist> Disables MAC address learning on one or more

ports for security purposes. If MAC address

learning is disabled, only broadcast traffic and

packets destined to a permanent MAC address

matching that port number, are forwarded. The

default setting is enabled.
