Qos Classifier-Map Oui 00:12:3B Qos - Black Box SmartPath LWN602A User Manual

QoS Policy: "voice"
Voice
The policy assigns the highest priority to voice traffic (class 6). For each voice session up to
512 Kbps, cluster members provide "strict" forwarding; that is, they forward traffic immediately
without queuing it.
Streaming
Media
Because streaming media (class 5) needs more bandwidth than voice does, the policy
defines a higher forwarding rate for it: 20,000 Kbps. It sorts streaming media into forwarding
queues using the WRR (weighted round robin) mechanism. It also prioritizes streaming media
by assigning a higher weight (90) than it assigns data traffic (class 3 = 60, class 2 = 30).
Data
The policy sorts class 3 and 2 traffic into forwarding queues using WRR and defines the highest
forwarding rate: 54,000 Kbps or 1,000,000 Kbps, depending on the SmartPath AP model that
you are configuring. It gives class 3 (for e-mail protocols SMTP and POP3) a higher WRR
weight (60) so that the SmartPath AP queues more e-mail traffic in proportion to other types of
traffic in class 2, which has a weight of 30 by default. As a result, e-mail traffic has a better
chance of being forwarded than other types of traffic when bandwidth is scarce.
Class 2 is for all types of traffic not mapped to an Black Box class—such as HTTP for example.
NOTE: This example assumes that the RADIUS and AD servers were previously configured and populated with user accounts and
have been serving a wired network (not shown). The only additional configuration is to enable the RADIUS server to accept
authentication requests from the SmartPath APs.
Finally, you create a user profile "employee-net" and apply the QoS policy "voice" to the user profile on each cluster member.
You also configure the RADIUS server to return attributes in its authentication responses to indicate the user group to which the
cluster members then assign users.
Step 1: Map traffic types to QoS classes on SmartPath AP-1.
1. Map the MAC organizational unit identifier (OUI) of network users' VoIP phones to Class 6.

qos classifier-map oui 00:12:3b qos 6

In this example, all network users use VoIP phones from the same vendor whose OUI (that is, the MAC address prefix ) is
00:12:3b. When SmartPath AP-1 receives traffic from a client whose source MAC address contains this OUI, it assigns it to Class
6.

* You do not need to enter this command because it just sets the default
values for class 2. It is shown to provide contrast with the previous command.
