To configure MAC OUI numbers for VoIP equipment:
1. Click Configuration, Voice VLAN, OUI.
2. Click “Add new entry.”
3. Enter a MAC address that specifies the OUI for VoIP devices in the network, and enter a
description for the devices.
4. Click Save.
4.18. Quality of Service (QoS)
All switches or routers that access the Internet rely on class information to provide the same
forwarding treatment to packets in the same class. Class information can be assigned by end
hosts, or switches or routers along the path. Priority can then be assigned based on a
general policy, or a detailed examination of the packet. However, note that detailed
examination of packets should take place close to the network edge so that core switches
and routers are not overloaded.
Switches and routers along the path can use class information to prioritize the resources
allocated to different traffic classes. The manner in which an individual device handles traffic
is called per-hop behavior. All devices along a path should be configured in a consistent
manner to construct a consistent end-to-end Quality of Service (QoS) solution.
This section describes how to specify which data packets have greater precedence when
traffic is buffered in the switch due to congestion. This switch provides four priority queues for
each port. Data packets in a port's high-priority queue will be transmitted before those in the
lower-priority queues. You can set the default priority for each interface, the queuing mode,
and queue weights.
Configuring Port Classification
The switch also allows you to configure QoS classification criteria and service policies. The
switch’s resources can be prioritized to meet the requirements of specific traffic types on a
per hop basis. Each packet is classified upon entry into the network based on Ethernet type,
VLAN ID, TCP/UDP port, DSCP, ToS, or its VLAN priority tag. Based on configured network
policies, different kinds of traffic can be marked for different kinds of forwarding.
Use the QoS Ingress Port Classification page to set the basic QoS parameters for a port,
including the default traffic class, DP level (IEEE 802.1p), user priority, drop eligible indicator,
classification mode for tagged frames, and DSCP-based QoS classification.
