Configuring FDB Entries

To configure entries in the FDB, use the commands listed in Table38.

Table 3 8: FDB Configuration Commands

Command Description
clear fdb [{<mac_address> | vlan <name>
| ports <portlist>}] Clears dynamic FDB entries that match the filter.
When no options are specified, the command
clears all FDB entries.
config fdb agingtime <number> Configures the FDB aging time. The range is 15
through 1,000,000 seconds. The default value is
300 seconds. A value of 0 indicates that the entry
should never be aged out.
create fdbentry <mac_address> vlan
<name> ports [<portlist> | all] {{qosprofile
<qosprofile> {ingress-qosprofile
<qosprofile>}} | {ingress-qosprofile
<qosprofile> {qosprofile <qosprofile>}}
Creates a permanent static FDB entry. Specify the
following:
•mac_address — Device MAC address, using
colon separated bytes.
•name — VLAN associated with MAC address.
•portlist — Port numbers associated with
MAC address.
•qosprofile — QoS profile associated with
destination MAC address of the egress port.
•ingress-qosprofile — QoS profile
associated with the source MAC address of the
ingress port.
If more than one port number is associated with a
permanent MAC entry, packets are multicast to the
multiple destinations.
create fdbentry <mac_address> vlan
<name> dynamic {{qosprofile <qosprofile >
{ingress-qosprofile <qosprofile>}} |
{ingress-qosprofile <qosprofile> {qosprofile
<qosprofile>}}
Creates a permanent dynamic FDB entry. Assigns
a packet with the specified MAC address and VLAN
to a specific QoS profile. If you only specify the
ingress QoS profile, the egress QoS profile defaults
to none, and vice-versa. If both profiles are
specified, the source MAC address of an ingress
packet and the destination MAC address of an
egress packet are examined for QoS profile
assignment.
create fdbentry <mac_address> vlan
<name> blackhole {source-mac | dest-mac
| both}
Creates a blackhole FDB entry. Specify:
•source-mac — The blackhole MAC address
matches the ingress source MAC address.
•dest-mac — The blackhole MAC address
matches the egress destination MAC address.
•both — The blackhole MAC address matches
the ingress source MAC address or the egress
destination MAC address.
delete fdbentry {<mac_address> vlan
<name> | all} Deletes one or all permanent 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.
