Mitel 6867i Administrator's Manual page 197

The Differentiated Services Code Point (DSCP) value is stored in the first six bits of the ToS
field. Each DSCP specifies a particular per-hop behavior that is applied to a packet.
The following parameters allow an administrator to configure ToS, QoS, and DiffServ QoS for
VLAN:
PARAMETERS IN CONFIGURATION FILES
GLOBAL
tagging enabled
priority non-ip
LAN PORT
vlan id
tos priority map
tos priority map
tos priority map
PC PORT
vlan id port 1
QoS eth port 1 priority
Notes:
1. In order for the software to successfully maintain connectivity with a network using
VLAN functionality, the IP phone reboots if you modify the "tagging enabled" (VLAN
Enable in the Web UI), "vlan id", or "vlan id port 1" parameters.
2. Setting the LAN Port VLAN ID (vlan id) to 4095 and PC Port VLAN ID (vlan id port
1) to any ID from 1 to 4094 will allow frames from the PC Port (containing a VLAN
ID) to be untagged before being forwarded to the LAN Port and frames from the
LAN Port (without a VLAN ID) to be tagged with the configured VLAN ID before
being forwarded to the PC Port. For configuring this feature via the Phone UI and
the Mitel Web UI, see
this feature using the configuration files, see Appendix A, the section,
Area Network (VLAN) Settings"
3. Alternatively setting the LAN Port VLAN ID (vlan id) to any ID from 1 to 4094 and
PC Port VLAN ID (vlan id port 1) to 4095 will allow frames from the LAN Port
(containing a VLAN ID) to be untagged before being forwarded to the PC Port and
frames from the PC Port (without a VLAN ID) to be tagged with the configured VLAN
ID before being forwarded to the LAN Port. For configuring this feature via the Phone
UI and the Mitel Web UI, see
configuring this feature using the configuration files, see Appendix A, the section,
"Virtual Local Area Network (VLAN) Settings"
DSCP Range/VLAN Priority Mapping
DSCP bits in the ToS field of the IP header are set for RTP, RTCP, and SIP packets using either
the default values or the values configured via the "tos sip", "tos rtp", and "tos rtcp"
parameters.
