Media traffic type is assigned ‘Premium media’ CoS, Management traffic type is assigned
‘Bronze’ CoS, and Control traffic type is assigned ‘Premium control’ CoS. For example,
RTP/RTCP traffic is assigned the Media VLAN ID and ‘Premium media’ CoS, whereas Web
traffic is assigned the Management VLAN ID and ‘Bronze’ CoS. Each of these parameters
can be configured with a 802.1p/Q value: traffic type to VLAN ID, and CoS to 802.1p
priority.
Figure 8-2: Multiple Network Interfaces and VLANs
Notes:
•
For security, the VLAN mechanism is activated only when the device is
loaded from the flash memory. Therefore, when using BootP:
Load an
ini
file with VlanMode set to 1 and SaveConfiguration set to 1.
Then (after the device is active) reset the device with TFTP disabled or
by using any method except for BootP.
•
For information on how to configure VLAN parameters, refer to
''Configuring the IP Settings'' on page
50 .
•
•
The device must be connected to a VLAN-aware switch and the switch’s
PVID must be equal to the device’s native VLAN ID.
The mapping of an application to its CoS and traffic type is shown in the table below:
