Auto Surveillance VLAN
Auto Surveillance Properties
This window is used to configure the auto surveillance VLAN global settings and display the ports
surveillance VLAN information.
To view the following window, click L2 Features > VLAN > Auto Surveillance VLAN > Auto
Surveillance Properties, as shown below:
The fields that can be configured for Global Settings are described below:
Parameter Description
Surveillance VLAN State
Select this option to enable or disable the surveillance VLAN state.
Surveillance VLAN ID
Enter the surveillance VLAN ID. The range is from 2 to 4094.
Surveillance VLAN CoS
Select the priority of the surveillance VLAN from 0 to 7.
Aging Time
Enter the aging time of surveillance VLAN. The range is from 1 to
65535 minutes. The default value is 720 minutes. The aging time
is used to remove a port from surveillance VLAN if the port is an
automatic surveillance VLAN member. When the last surveillance
device stops sending traffic and the MAC address of this
surveillance device is aged out, the surveillance VLAN aging timer
will be started. The port will be removed from the surveillance
VLAN after expiration of surveillance VLAN aging timer. If the
surveillance traffic resumes during the aging time, the aging timer
will be reset and stop.
ONVIF Discover Port
Enter the TCP/UDP port number here. The range is either 554, or
from 1025 to 65535. This is used to configure the TCP/UDP port
number for RTSP stream snooping. ONVIF-capable IPC and
ONVIF-capable NVR utilize WS-Discovery to find other devices.
Once IPCs are discovered, the Switch can further discover NVRs
by snooping RTSP, HTTP, and HTTPS packets between NVRs
and IPCs. These packets cannot be snooped if the TCP/UDP port
is not equal to the RTSP port number.
