3.6
Redundancy
This section allows you to configure 1:1 redundancy with fail over in which a secondary FX, with the same
configuration as the primary FX, polls for the existence of the primary FX, and takes over its non-
management IP addresses when the primary does not respond to the poll. When the primary FX comes
back up, the secondary FX will relinquish the IP addresses. This section also allows you to configure
shared configurations between members of an appliance pool. This is useful to synchronize
configurations in a WCCP cluster.
3.6.1 Redundancy Configuration Settings
Redundancy
This must be enabled if either the 1:1 Redundancy with fail over or "Automatically synchronize
configurations" feature is required.
Primary Appliance:
This is the host name of the primary (master) FX.
Secondary Appliance:
Enter the 'short' host name or IP address of the secondary FX that will engage if the primary FX becomes
inoperable. The secondary appliance continually polls the primary appliance and if the primary appliance
does not respond then the secondary appliance asserts control over the realm of IP addresses that
external clients connect to. When the primary appliance becomes operational again, the secondary will
relinquish control of these IP addresses. This parameter is not required if only synchronizing configuration
changes to member pool appliances is being configured.
Authentication Key:
By default, this key is generated automatically. For 1:1 Redundancy with fail over, the secondary
appliance's key must match the primary appliance's key. This requires manually copying the primary
appliance's key and pasting it into this field on the secondary appliance (after deleting the secondary
appliance's generated key).
