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:
1. You must disable the "Validate Certificates" field in order for the phone to
2. 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 Opera-
tion->Reset, and restart the phone for the changes to take affect.
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.
Note: All latest VLAN functionality is backwards compatible with IP Phone Releases 1.3
and 1.3.1.
VLAN on the IP phones is disabled by default. When you enable VLAN, the IP phone provides
defaults for all VLAN parameters. If you choose to change these parameters, you can configure
them using the configuration files, the IP Phone UI, or the Mitel 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.
