Protected Station Virtual IP Address (PVIP)
The Protected Station Virtual IP Address (PVIP) is the IP Address of the active radio whether it is the primary
radio or the secondary radio.
The PVIP is available in both bridge and router modes.
In router mode, the PVIP can be used as ‘next hop’ IP address by external routers to reach the protected
station so the protection station switch will always be transparent to the external devices and routers.
In both bridge and router modes, the PVIP is used in terminal server mode in remote protected stations.
The PVIP is used to reach the protected remote radio from the SCADA master connected to base station in
terminal server mode.
Note: The radio IP address should be used for SNMP management as using the PVIP for SNMP management
will result in undefined behaviour if a switch-over occurs during an SNMP transaction. Thus, using PVIP for
SNMP network management is not recommended.
After a switch-over, new active radio owns the PVIP and will send out a gratuitous ARP to clear the MAC
learning tables of upstream switches/routers.
Set the static IP Address of the PVIP using the standard format xxx.xxx.xxx.xxx. The default IP address is
0.0.0.0.
Subnet Mask
Set the Subnet Mask of the radio using the standard format xxx.xxx.xxx.xxx. The default subnet mask is
255.255.0.0.
Gateway
Set the Gateway address of the radio, if required, using the standard format xxx.xxx.xxx. The default
Gateway is 0.0.0.0.
