AXIS 216FD/FD-V - System Options

FTP

The FTP server running in the AXIS 216FD/FD-V enables the upload of e.g. new firmware,

user applications, etc. Check the box to enable the service.

Network Traffic
Connection Type
- The default setting is Auto-negotiate, which means that the correct

speed is automatically selected. If necessary, you can set the connection speed by selecting

it from the drop-down list.

Maximum bandwidth - To minimize the impact on other services running on your

network, it is possible to configure the maximum network bandwidth the product will be

allowed to use. Specify the maximum bandwidth (in Mbit/s or kbit/s) allowed, or set to

Unlimited.

QoS (Quality of service)

Quality of Service (QoS) provides the means to guarantee a certain level of a specified

resource to selected traffic on a network. Quality can be defined as e.g. a maintained level

of bandwidth, low latency, no packet losses, etc. The main benefits of a QoS-aware

network can be summarized as:

• The ability to prioritize traffic and thus allow critical flows to be served before

flows with lesser priority.

• Greater reliability in the network, thanks to the control of the amount of band-

width an application may use, and thus control over bandwidth races between

applications.

The QoS in Axis network video products marks the data packets for various types of

network traffic originating from the product. This makes it possible for network routers

and switches to e.g. reserve a fixed amount of bandwidth for these types of traffic. The

AXIS 216FD/FD-V marks the following types of traffic:

• video
• audio
• event/alarm
• management network traffic.

QoS Settings

For each type of network traffic supported by your Axis network video product, enter a

DSCP (Differentiated Services Codepoint) value. This value is used to mark the traffic’s IP

header. When the marked traffic reaches a network router or switch, the DSCP value in the

IP header tells the router or switch which type of treatment to apply to this type of traffic,

for example, how much bandwidth to reserve for it.
