prescribe the bandwidth management and priority handling for that traffic grouping. This level of
packet filtering has no impact on performance.

MAC-Based Traffic Groupings

QoS profiles can be assigned to destination MAC addresses. MAC-based traffic groupings are
configured using the following command:

create fdbentry <mac_address> vlan <name> [blackhole | port <portlist> | dynamic]

qosprofile <qosprofile>

The MAC address options, defined below, are as follows:

Permanent

Dynamic

Blackhole

Permanent MAC addresses

Permanent MAC addresses can be assigned a QoS profile whenever traffic is destined to the MAC
address. This can be done when you create a permanent FDB entry. For example:

create fdbentry 00:11:22:33:44:55 vlan default port 1:4 qosprofile qp2

Dynamic MAC Addresses

Dynamic MAC addresses can be assigned a QoS profile whenever traffic is destined to the MAC
address. For any port on which the specified MAC address is learned in the specified VLAN, the port is
assigned the specified QoS profile. For example:

create fdbentry 00:11:22:33:44:55 vlan default dynamic qosprofile qp3

The QoS profile is assigned when the MAC address is learned. If a client's location moves, the assigned
QoS profile moves with the device. If the MAC address entry already exists in the FDB, you can clear
the forwarding database so that the QoS profile can be applied when the entry is added again. Use the
following command to clear the FDB:

clear fdb

Blackhole MAC Address

Using the

blackhole

option configures the switch to not forward any packets to the destination MAC

address on any ports for the VLAN specified. The

blackhole

option is configured using the following

command:

create fdbentry 00:11:22:33:44:55 vlan default blackhole

Verifying MAC-Based QoS Settings

To verify any of the MAC-based QoS settings, use either the command

show fdb permanent

or the command

show qosprofile <qosprofile>
