system having to instruct it to do so. When the standby system assumes the active role, it can notify a network
management system through an SNMP trap.
The communication between the active member and standby member (life line, transfer of the configuration via FTP) goes
through an IP connexion, as explained here-below.
In the event of an outage of the active member, the IP audio services is interrupted a few seconds..
13.2 Installation of a HA pair of IQOYA SERV/LINK
⚠
The two IQOYA SERV/LINKs must be identical : same model, same type and same number of I/Os.
One network interface of the IQOYA SERV/LINK’s must be reserved for the devices to advertise their current state and
health to one another (life line). The network interface can be a dedicated Eth interface, or a logical interface belonging to a
VLAN. This network interface is called the HA network interface. Another network interface must be dedicated to all the other
IP services and in particular the IP audio services. It is called the audio network interface. The floating IP address will be
shared by these audio network interfaces.
To install a HA pair of IQOYA SERV/LINK, follow these steps:
1. Choose and set the IP configuration of the HA network interface on both devices. The two HA interfaces must be in
the same subnetwork.
2. Choose and set the IP configuration of the audio network interface on both devices. The two audio interfaces must
be in the same subnetwork.
⚠
The subnetwork of the HA interfaces and the subnetwork of the audio interfaces must be separated
subnetworks.
3. Choose a free IP address in the same subnetwork as the audio network interfaces. This IP address will be the
floating IP Address (VIP) shared by the two audio network interfaces.
4. Establish the physical network connections.
⚠
The connection between the HA network interfaces must be very reliable. For better reliability, it is
strongly recommended to establish the physical connection between the HA network interfaces using only a
network cable (as in the example below). However the physical connection between the HA network
interfaces can be established via network switches provided that these switches are themselves part of a
network HA system (like STP for instance).
It is also strongly recommended to force the HA network link at 100M Full Duplex.
Here is an example of an installation:
