50 AXIS 210A/211A - System Options
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
following types of traffic are marked:
• live video
• live audio
• event/alarm traffic
• 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.
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 addresses for your primary and secondary mail servers in the
fields provided, to enable the sending of event and error e-mail messages from the camera
to predefined addresses via SMTP.
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 com-
munity is the the group of network devices using SNMP.
• SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled.
