H.323 User's Manual 9. Networking Capabilities
Version 5.0 287 December 2006
For the mapping of an application to its class-of-service and traffic type, refer to Table 9-1
on page 287.
Media traffic type is assigned ‘Premium media’ class of service, Management traffic type is
assigned ‘Bronze’ class of service, and Control traffic type is assigned ‘Premium control’
class of service.
For example, RTP/RTCP traffic is assigned the Media VLAN ID and ‘Premium media’ class
of service, whereas Web traffic is assigned the Management VLAN ID and ‘Bronze’ class
of service. Each of these parameters can be configured with an 802.1p/q value: traffic type
to VLAN ID, and class of service to 802.1p priority.
Notes:
• As a safety measure, the VLAN mechanism is activated only when the
gateway is loaded from the flash memory. Therefore, when using
BootP:
Load an ini file with ‘VlanMode = 1’ and ‘SaveConfiguration = 1’. Then
(after the gateway is active) reset the gateway with TFTP disabled, or
by using any method except for BootP.
• The gateway must be connected to a VLAN-aware switch, and the
switch’s PVID must be equal to the gateway’s native VLAN ID.
For information on how to configure VLAN parameters, refer to Section 5.6.1.5 on page
138.
