112 Summit 200 Series Switch Installation and User Guide
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.
