ROUPINGS
IP-based traffic groupings are based on any combination of:
• IP source or destination address
• TCP/UDP or other Layer 4 protocol
• TCP/UDP port information
IP-based traffic groupings are defined using access lists. Access lists are discussed in
detail in Chapter 16. 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 no impact on performance.

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
• Broadcast/unknown rate limiting
P
ERMANENT 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 (spell out) (FDB)
entry. For example:
create fdbentry 00:11:22:33:44:55 vlan default port 4:1 qosprofile qp2
