Virtual LAN (optional)
Virtual Local Area Network (VLAN) is a feature on the IP phone that allows for multiple logical Ethernet interfaces to send
outgoing RTP packets over a single physical Ethernet as described in IEEE Std 802.3. On the IP phone, you configure a
VLAN ID that associates with the physical Ethernet port.
By configuring specific VLAN parameters, the IP phones have the capability of adding and removing tags, and processing
the ID and priority information contained within the tag.
VLAN on the IP phones is disabled by default. When you enable VLAN, the IP phone provides defaults for all VLAN param-
eters. If you choose to change these parameters, you can configure them using the configuration files, the IP Phone UI, or
the Aastra Web UI.
The following sections describe the VLAN features you can configure on the IP phones.
Type of Service (ToS), Quality of Service (QoS), and DiffServ QoS
ToS is an octet as a field in the standard IP header. It is used to classify the traffic of the different QoSs.
QoS provides service differentiation between IP packets in the network. This service differentiation is noticeable during
periods of network congestion (for example, in case of contention for resources) and results in different levels of network
performance.
Port 0 is the Ethernet LAN Port connected to the network. Port 1 is the Ethernet PC Port used for passthrough to a PC.
Differentiated Service (DiffServ) QoS is class-based where some classes of traffic receive preferential handling over other
traffic classes.
The Differentiated Services Code Point (DSCP) value is stored in the first six bits of the ToS field. Each DSCP specifies a par-
ticular per-hop behavior that is applied to a packet.
The following parameters allow an administrator to configure ToS, QoS, and DiffServ QoS for VLAN:
5. If you require the download of User-provided certificates in a .PEM formatted file, enter the file name in the format <filename.pem> in the
“Trusted Certificates Filename” field. For example:
trustedCerts.pem
This parameter specifies a file name for a .PEM file located on the configuration server. This file contains the User-provided certificates in
PEM format. These certificates are used to validate peer certificates.
Notes:
• You must disable the “Validate Certificates” field in order for the phone to accept the User-provided certificates.
• This parameter requires you restart the phone in order for it to take affect.
6. Click Save Settings to save your changes.
7. If you entered a filename in the “Trusted Certificates Filename” field, click on Operation->Reset, and restart the phone for the changes
to take affect.
Note:
All latest VLAN functionality is backwards compatible with IP Phone Releases 1.3 and 1.3.1.
