Module configuration parameters

  • SOPKEY 1 (default active): Fill in the sopkey of the default active SOP.
  • Standby IP 1: Fill in the eth0 standby ip address of the default active SOP. This IP address will always be bound on the interface.
  • SOPKEY 2: Fill in the sopkey of the first standby SOP.
  • Standby IP 2: Fill in the eth0 standby ip address of the first standby SOP. This IP address will always be bound on the interface.
  • SOPKEY 3: Fill in the sopkey of the second standby SOP.
  • Standby IP 3: Fill in the eth0 standby ip address of the second standby SOP. This IP address will always be bound on the interface.
  • SOPKEY 4: Fill in the sopkey of the third standby SOP.
  • Standby IP 4: Fill in the eth0 standby ip address of the third standby SOP. This IP address will always be bound on the interface.
  • Standby IP 1 eth1 and an optional subnet mask: Fill in the eth1 standby ip address of the default active SOP. This IP address will always be bound on the interface. Optionally you can also specify a subnet mask with a comma in between. No spaces are allowed. (e.g. 192.168.0.1,255.255.255.0)
  • Standby IP 2 eth1 and an optional subnet mask: Fill in the eth1 standby ip address of the first standby SOP. This IP address will always be bound on the interface. Optionally you can also specify a subnet mask with a comma in between. No spaces are allowed. (e.g. 192.168.0.2,255.255.255.0)
  • Standby IP 3 eth1 and an optional subnet mask: Fill in the eth1 standby ip address of the second standby SOP. This IP address will always be bound on the interface. Optionally you can also specify a subnet mask with a comma in between. No spaces are allowed. (e.g. 192.168.0.3,255.255.255.0)
  • Standby IP 4 eth1 and an optional subnet mask: Fill in the eth1 standby ip address of the third standby SOP. This IP address will always be bound on the interface. Optionally you can also specify a subnet mask with a comma in between. No spaces are allowed. (e.g. 192.168.0.4,255.255.255.0)
  • Sanity Check Timer: Number of second after which the status of the HA need to be done
  • Admin Email: Email to which a report need to be sent in case of HA status change or if the sanity check failed
ALERT! The optional subnet mask for eth1 is only taken into account when there is no active IP configured in the network module for eth1. This allows a configuration where there is a shared address on eth0, but no shared address on eth1.
