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, 4 for RTP, and 4 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.
The following table shows the DSCP range/VLAN priority mapping.

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. When the LAN Port (vlan id) and the PC Port (vlan id port 1)
parameters have the same value, VLAN functionality is compatible with
earlier IP phone software releases.
If you set the PC Port (vlan id port 1) to 4095, all untagged packets are
sent to this port. For configuring this feature via the Phone UI and the
Aastra Web UI, see "Configuring VLAN (optional)"
configuring this feature using the configuration files, see Appendix A, the
section, "Virtual Local Area Network (VLAN) Settings"
