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.
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.
the 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.
IP protocol configuration
You can configure whether the VCS uses IPv4, IPv6 or Both protocols. The default is Both.
n
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.

n
IPv6: it only accepts registrations from endpoints using an IPv6 address, and only takes calls between two
endpoints communicating via IPv6. It communicates with other systems via IPv6 only.

n
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.

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 endpoint. After the endpoint has registered using either IPv4 or IPv6, the VCS only sends
calls to it using this addressing scheme. Calls made to that endpoint from another device using the other
addressing scheme are converted (gatewayed) by the VCS.

All IPv6 addresses configured on the VCS are treated as having a /64 network prefix length.
IPv4 to IPv6 gatewaying (interworking)
The VCS can act as a gateway for calls between IPv4 and IPv6 devices. To enable this feature, select an IP
protocol of Both. Calls for which the VCS is acting as an IPv4 to IPv6 gateway are traversal calls and
require a traversal call license.
