Mitel 6800i Series SIP Phone Release 4.1.0 Administrator Guide
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.
When the VLAN global configuration parameter, "tagging enabled" is set to 1, VLAN priority
for IP packets is mapped to the DSCP value instead of a single priority for all packets. An
administrator can also configure VLAN priority for non-IP packets using the "priority non-ip"
parameter.
Since the default DSCP settings for SIP, RTP, and RTCP are 26, 46, and 46 respectively, this
results in corresponding default VLAN priorities of 3 for SIP, 5 for RTP, and 5 for RTCP (based
on the settings in the table
You can change the default parameters by modifying just the DSCP values, just the VLAN
priority values, or by modifying all values.
