C H A P T E R 8 Quality of Service (QoS)
135
• TCP/UDP port information
IP-based traffic groupings are defined by the use of access lists. By
supplying a named QoS profile at the end of the access list
command syntax, you can prescribe the bandwidth management
and priority handling for that traffic grouping. This level of packet
filtering has zero negative impact on performance.
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
<qosprofile>
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
4:1 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
