NSTALLATION
•
From a
menu
where it can be manually set (both the phone- and
the PC port).
It is possible to change the different VLAN options from the menu in the
boot sequence. The following menu is shown (for DBC 425 as an
example):
Figure 56: Start up menu in DBC 425
Enter the administrator mode, go down in the
Network
list until the line
VLAN for Phone Port
occurs. Change the value to one of the options
below:
•
No VLAN
. VLAN shall not be used, but if a VLAN identity is read
from the configuration file, VLAN will be used.
•
Auto.
This is the default value when the phone is delivered from the
factory. If the phone receives a VLAN identity list from DHCP (in
option 43) or if there is a VLAN identity defined in the configuration
file it will be used. The VLAN identity received from DHCP has
priority over the configuration file. For more information, 7.20.1
Automatic VLAN detection with DHCP on page 53 and 7.20.2
Assigning the VLAN identity via the configuration file on page 53.
•
Manually
. The manually entered VLAN identity will be used, 7.20.3
Manual setting of the VLAN identity on page 54. If the manually
entered VLAN identity shall be used, the [L2QOS] header in the
configuration file has to be omitted.
Even when VLAN is not used this parameter can have the default value
Auto
.
Concerning the priority of the frames: For outgoing frames the following
priorities will be set at level 2 for each frame by default, when VLAN is
used:
•
For frames
originating in the phone
the default value will be 6,
meaning voice traffic with less than 10 ms latency.
•
For frames
originating in the PC
the default value is 0, meaning
best effort.
The priorities can be changed via the configuration file, see the descrip-
tion for
CONFIGURATION FILE FOR DBC 42X
.
