110 Matrix PRASAR UCS System Manual
AMP100/VARTA ADR100/ VARTA WIN200 with the server using a secure protocol. The system will listen
for the configuration request from the VARTA clients on this port. You must also configure the Secure
SPARSH port value as the Server Port along with the Server Address in the VARTA clients.
Valid range: 443 or any value ranging from 1025 to 60000. Default: 443.
When the system is set to default, the port values of HTTPS Port, SPARSH Port and Secure SPARSH Port
are not set to default.
Layer 2 VLAN/Cos

• Layer 2 VLAN/CoS: This parameter is to be configured if the WAN port is to be connected in VLAN
network.
This parameter enables the PRASAR UCS to add VLAN header to the packets generated by it. The VLAN
header consists of the VLAN ID (12-bit) and Class of Service (CoS, 3-bit) for prioritization of
traffic
13
.
VLAN Tag is applied on all packets generated by system (SIP, RTP, DNS, ARP, etc.), whereas CoS bits are
applied only for SIP and RTP packets generated by system.
The corresponding meaning of CoS bits with respect to traffic type is as follows:
• Enable Layer 2 VLAN/CoS: Select this check box, if you want all packets generated by the system
(SIP, RTP, DNS, ARP, etc.) to be tagged with VLAN ID as configured. The CoS bits as configured for
SIP and RTP packets will be included in the VLAN header. Default: Disabled.
13. The IEEE 802.1P standard allows Layer2 switches to prioritize the traffic, thus providing Quality of Service (QoS), better handling
of data that pass over a network, thereby resulting in greater reliability and quality. Quality of Service (QoS) on Layer2 is referred to
as Class of Service (CoS) which is defined by IEEE 802.1P.
