Configuring FDB Entries
To configure entries in the FDB, use the commands listed in Table 29.
Table 29: 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.
