Configuring Qos Priority Settings For Voice Traffic On An Interface; Configuring A Port To Operate In Automatic Voice Vlan Assignment Mode - HP 3600 v2 series Configuration Manual

Configuring QoS priority settings for voice traffic on an
interface
In voice VLAN applications, you can improve the quality of voice traffic by configuring the appropriate
QoS priority settings, including the Class of Service (CoS) and Differentiated Services Code Point (DSCP)
values, for voice traffic. Voice traffic carries its own QoS priority settings. You can configure the device
either to modify or not to modify the QoS priority settings carried by incoming voice traffic.
Follow these steps to configure QoS priority settings for voice traffic:
To do...
Enter system view
Enter Layer 2 Ethernet interface
view
Configure the interface to trust the
QoS priority settings in incoming
voice traffic, but not to modify the
CoS and DSCP values marked for
incoming traffic of the voice VLAN
Configure the interface to modify
the CoS and DSCP values marked
for incoming traffic of the voice
VLAN into specified values
NOTE:
Configure the QoS priority settings for voice traffic on an interface before you enable voice VLAN on the
interface. If the configuration order is reversed, your priority trust setting will fail.
Configuring a port to operate in automatic voice VLAN
assignment mode
Follow these steps to set a port to operate in automatic voice VLAN assignment mode:
To do...
Enter system view
Set the voice VLAN
aging time
Enable the voice VLAN
security mode
Add a recognizable
OUI address
Use the command...
system-view
interface interface-type
interface-number
voice vlan qos trust
voice vlan qos cos-value
dscp-value
Use the command...
system-view
voice vlan aging minutes
voice vlan security enable
voice vlan mac-address oui
mask oui-mask [ description
text ]
156
Remarks

Required
Use either command
By default, an interface modifies the CoS
value and the DSCP value marked for voice
VLAN traffic into 6 and 46 respectively.
The voice vlan qos command and the voice
vlan qos trust command can overwrite each
other, whichever is configured last.
Remarks

Optional
By default, the aging time of a voice VLAN is 1440
minutes.
The voice VLAN aging time configuration is only
applicable on ports in automatic voice VLAN
assignment mode.
Optional
By default, the voice VLAN security mode is enabled.
Optional
By default, each voice VLAN has default OUI
addresses configured. For the default OUI addresses
of different vendors, see Table 15.
