User's Manual 32. HA Configuration
32 HA Configuration
This section describes the configuration of the HA system.
32.1 Initial HA Configuration
By default, HA is disabled on the device. When a device is loaded with valid HA
configuration and it is the first device to be loaded, it becomes the active device. The
second device that is loaded with HA configuration becomes the redundant (standby)
device.
32.1.1 Network Topology Types and Rx/Tx Ethernet Port Group
Settings
The initial configuration of HA depends on how you want to deploy your HA system in the
network. The Maintenance Interface, used for the HA link between Active and Redundant
units, should be configured on a dedicated Ethernet Port Group, separate from the other
interfaces. The required receive (Rx) and transmit (TX) mode for the port pair in the
Ethernet Port Group used by the Maintenance interface is as follows:

For Geographical HA (both units are located far from each other), 2Rx/1Tx port mode
connected to a port aggregation switch is the recommended option:


If the Maintenance ports of both devices are connected directly to each other without
intermediation of switches, configure the mode to
2RX/1TX :
