Quality of Service (QoS)
IP-Based Traffic Groupings
IP-based traffic groupings are based on any combination of the following items:
•
IP source or destination address
• TCP or UDP protocols
•
TCP/UDP port information
IP-based traffic groupings are defined using access lists. Access lists are discussed in detail in “IP Access
Lists (ACLs)” on page 142. 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.
For example, to create an IP-based traffic grouping, use the following commands:
create access-mask amask source-ip / 24 dest-ip / 24 precedence 2000
create access-list alist "amask" dest-ip 10.1.2.1/24 source-ip 10.1.1.1/24 permit
qosprofile qp3
To create a MAC-based traffic grouping, use this command:
create fdbentry 00 : 11 : 22 : 33 : 44 : 55 vlan "Default" dynamic qosprofile "QP3"
MAC-Based Traffic Groupings
QoS profiles can be assigned to destination MAC addresses. MAC-based traffic groupings are
configured using the
create fdb...
command:
The MAC address options, defined below, are as follows:
•
Permanent
• Dynamic
• Blackhole
NOTE
On the Summit 400 broadcast MAC entries may not be associated with a QoS.
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 using the following command:
create fdbentry <mac_address> vlan <vlan name> ports [<portlist> | all] {qosprofile
<qosprofile>}{ingress-qosprofile <inqosprofile>}
For example:
create fdbentry 00:11:22:33:44:55 vlan default port 4:1 qosprofile qp2
