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.
