FDB Configuration Examples
The following example adds a permanent entry to the FDB:
create fdbentry 00:E0:2B:12:34:56 vlan marketing port 4
The permanent entry has the following characteristics:
• MAC address is 00:E0:2B:12:34:56.
• VLAN name is marketing.
• 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.
Displaying FDB Entries
To display FDB entries, use the following command:
show fdb {<mac_address> | vlan <name> | ports <portlist> | permanent}
where:
If you enter this command with no options specified, the command displays all FDB entries.
disable learning port <portlist> Disables MAC address learning on one or more
ports for security purposes. If MAC address
learning is disabled, only broadcast traffic, EDP
traffic, and packets destined to a permanent MAC
address matching that port number, are forwarded.
The default setting is enabled.
enable learning port <portlist> Enables MAC address learning on one or more
ports.
