Forwarding Database (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
How you display FDB entries depends on whether the switch is non-stacked or whether the switch is
configured in a stacked set of switches.
On a Non-stacked Switch
To display FDB entries on a non-stacked switch, use the following command:
show fdb {<mac_address> | vlan <name> | ports <portlist> | permanent | slot<n>}
where:
If you enter this command with no options specified, the command displays all FDB entries.
On a Stacked Set of Switches
To display the entire FDB on a slot including the local statistics, use the following command:
show fdb slot <n>
where:
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.
slot <n>
Displays the entries for a slot on a stack of switches.
