Traffic Groupings and Creating a QoS Policy
103
MAC-Based Traffic
Groupings
QoS profiles can be assigned to destination MAC addresses. The various
options that fall into this category are as follows:
■
Permanent
■
Dynamic
■
Blackhole
■
Broadcast/unknown rate limiting
MAC-based traffic groupings are configured using the following
command:
create fdbentry <mac_address> vlan <name> [blackhole | port
<portlist> | dynamic] qosprofile <qosname>
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
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 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.
