4 Web-based Switch Configuration
Configuration > Auto Surveillance VLAN > ONVIF NVR Information
The ONVIF (Open Network Video Interface Forum) NVR Information page displays the information on each
NVR connected to the switch. Including the port number, IP address, MAC address, IP-Camera number,
throughput and description relating to the cameras connected to the NVR, such as the group name, total
number of cameras and the port and IP address of each camera.

The QinQ Settings page allows user to enable or disable the Q-in-Q function. Q-in-Q is designed for service
providers to carry traffic from multiple users across a network.
Q-in-Q is used to maintain customer specific VLAN and Layer 2 protocol configurations even when the same
VLAN ID is being used by different customers. This is achieved by inserting SPVLAN tags into the
customer's frames when they enter the service provider's network, and then removing the tags when the
frames leave the network.
Customers of a service provider may have different or specific requirements regarding their internal VLAN
IDs and the number of VLANs that can be supported. Therefore customers in the same service provider
network may have VLAN ranges that overlap, which might cause traffic to become mixed up. So assigning a
unique range of VLAN IDs to each customer might cause restrictions on some of their configurations
requiring intense processing of VLAN mapping tables which may exceed the VLAN mapping limit. Q-in-Q
uses a single service provider VLAN (SPVLAN) for customers who have multiple VLANs. Customer's VLAN
IDs are segregated within the service provider's network even when they use the same customer specific
VLAN ID. Q-in-Q expands the VLAN space available while preserving the customer's original tagged packets
and adding SPVLAN tags to each new frame. Select Enabled or Disabled then click Apply to enable or
disable the Q-in-Q Global Settings.
From Port / To Port: A consecutive group of ports that are part of the VLAN configuration starting with the
selected port.
