QoS (Quality of Service)
Quality of Service (QoS) guarantees a certain level of a specified resource to selected traffic on a network. Quality can be
defined as a maintained level of bandwidth, low latency, and no packet losses. 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 bandwidth 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 reserve a fixed amount of bandwidth for these types of
traffic. The video encoders mark the following types of traffic:
• video
• 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 the type of treatment to apply to this type
of traffic, for example, how much bandwidth to reserve for it. Note that DSCP values can be entered in decimal or hex form,
but saved values are always shown in decimal.

SMTP (email)
Enter the host names (or IP addresses) and port numbers for your primary and secondary mail servers in the fields provided, to
enable the sending of notifications and image email messages from the video encoder to predefined addresses via SMTP.
If your mail server requires authentication, check the box for Use authentication to log in to this server and enter the
necessary information. See the online help
SNMP
The Simple Network Management Protocol (SNMP) allows remote management of network devices. Depending on the level of
security required, select the version of SNMP to use. The three levels of security are:
• SNMP v1 - includes no security.
• SNMP v2c - uses very simple security. The community name can be specified as a password for read or read/write access
to all supported SNMP objects. The community is the group of network devices using SNMP.
• SNMP v3 - provides encryption and secure passwords. HTTPS must be enabled.
Traps for SNMP v1/v2/v3
Traps are used by the video encoder blade to send messages to a management system for important events or status changes.
These settings are used with SNMP v1/v2. To activate trap reporting, enter the IP address of the management server, and
choose the trap community to use when sending a trap message to the management system.
SNMP v3 is a more secure version providing encryption and secure passwords. To use SNMP v3, HTTPS must be activated. To
use traps with SNMP v3 an SNMP v3 management application is needed.
See the online help for more information.
UPnP™
The video encoder blade includes support for UPnP™. UPnP™ is enabled by default, and the video encoder blade then is
automatically detected by operating systems and clients that support this protocol.
