5.5.2 VLAN Settings
Enable users to define devices (e.g. Base station, etc.) with different physical connection to communicate as if they are
connected on a single network segment.
The VLAN settings can be used on a managed network with separate Virtual LANs (VLANs) for sending voice and data
traffic. To work on these networks, the base stations can tag voice traffic it generates on a specific “voice VLAN” using
the IEEE 802.1q specification.

PARAMETER
DEFAULT VALUES
DESCRIPTION
VLAN ID
0
Is a 12-bit identification of the 802.1Q VLAN.
Permitted value(s): 0 to 4094 (only decimal values are accepted)
A VLAN ID of 0 is used to identify priority frames and ID of 4095 (i.e. FFF)
is reserved.
Null means no VLAN tagging or No VLAN discovery through DHCP.
VLAN USER
PRIORITY
0
This is a 3-bit value that defines the user priority.
Values are from 0 (best effort) to 7 (highest); 1 represents the lowest
priority. These values can be used to prioritize different classes of traffic
(voice, video, data, etc.).
Permitted value(s): 8 priority levels (i.e. 0 to 7)
VLAN
SYNCHRONIZATION
Disabled
Default disabled. By enabled the VLAN ID is automatic synchronized
between the bases in the chain. Bases will be automatic rebooted during
the synchronization.
For further help on VLAN configuration refer to Appendix.
5.5.3 DHCP Options

PARAMETER
DEFAULT VALUES
DESCRIPTION
PLUG-N-PLAY
Enabled
Enabled: DHCP option 66 to automatically provide PBX IP address to base.
5.5.4 Static IP settings
If there is no DHCP server present you need to set a static IP. When you plug-in the LAN cable and the Base station
don’t get IP from a DHCP server it uses RFC3927 Static IP fall back.
Static IP address fall back - RFC3927
If a base station boots without a DHCP server on the network, it boots up using static IP as defined in RFC3927.
Base continuously request IP and after 3min. the base enters static IP address in range: 169.254.x.x
