Network and System Settings
This section describes network services and settings related options that appear under the System menu of the web
interface. These options enable you to configure the VCS in relation to the network in which it is located, for example
its IP settings, firewall rules, intrusion protection and the external services used by the VCS (for example DNS, NTP
and SNMP).

Network Settings
Configuring Ethernet Settings
Use the Ethernet page (System > Network interfaces > Ethernet) to configure the speed of the connections between
the VCS and the Ethernet networks to which it is connected. The speed and duplex mode must be the same at both
ends of the connection. If you installed the Advanced Networking option, you can configure the speed and duplex
mode for each Ethernet port.
the VCS and the Ethernet networks to which it is connected. The speed and duplex mode must be the same at both
ends of the connection. If you installed the Advanced Networking option, you can configure the speed and duplex
mode for each Ethernet port.
The default Speed is Auto, which means that the VCS and the connected switch will automatically negotiate the
speed and duplex mode.
speed and duplex mode.
Note:
We recommend Auto unless the connected switch is unable to auto-negotiate. A mismatch in speed/duplex
mode between the two ends of the connection will cause packet loss and could make the system inaccessible.
Configuring IP Settings
The IP page (System > Network interfaces > IP) is used to configure the IP protocols and network interface settings
of the VCS.
of the VCS.
IP Protocol Configuration
You can configure whether the VCS uses IPv4, IPv6 or Both protocols. The default is Both.
■
IPv4: it only accepts registrations from endpoints using an IPv4 address, and only takes calls between two
endpoints communicating via IPv4. It communicates with other systems via IPv4 only.

Both: it accepts registrations from endpoints using either an IPv4 or IPv6 address, and takes calls using either
protocol. If a call is between an IPv4-only and an IPv6-only endpoint, the VCS acts as an IPv4 to IPv6
gateway. It communicates with other systems via either protocol.

Some endpoints support both IPv4 and IPv6, however an endpoint can use only one protocol when registering with
the VCS. Which protocol it uses is determined by the format used to specify the IP address of the VCS on the
