Forwarding Database (FDB)
FDB Configuration Examples
The following example adds a permanent entry to the FDB:
create fdbentry 00:E0:2B:12:34:56 vlan marketing port 1:4
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 1:4.
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 the following is true:
• mac_address — Displays the entry for a particular MAC address.
• vlan <name> — Displays the entries for a VLAN.
• ports <portlist> — Displays the entries for a slot and port combination.
• permanent — Displays all permanent entries, including the ingress and egress QoS profiles.
With no options, the command displays all FDB entries.
enable learning port <portlist> Enables MAC address learning on one or more
ports.
