26.5.2.1 Ethernet Frame Priority Header
The Mediant 8000 supports Ethernet frame Priority header as defined in the IEEE
802.1p and 802.1q standards. 3-bit priority value (from 0 to 7) may be assigned to
each network service class, applicable to the Mediant 8000 .
Ethernet Switch (ES) boards are configured to strictly prioritize processed traffic,
based on the Priority header. Packets with a higher priority value will be processed
prior to packets with a lower priority (within the same VLAN).
Note: Ethernet Frame Priority Header configuration will be activated only when
VLAN tagging is enabled for the corresponding subnet. See 'Working with VLANs'
on page 188 for details.
The Ethernet Frame Priority Header may be configured as follows:
For OAM subnet (Network, Gold and Bronze service classes) – open the Media
Gateway’s Network Settings configuration screen and configure parameters in
the Quality Of Service tab.
Note: This feature is not supported for an SC board configured with the ES-2
switch (only supported for the ES/6600 switch). In the case of the Media Gateway
board, both ES boards are supported.
For Media and Control subnets – open Network Profile’s configuration screen and
configure parameters in the Quality Of Service tab.
