User's Manual
Description

For Survivability mode for User-type IP Groups, the
parameter must be enabled (1 or 2).

If the parameter is enabled and the proxy uses the
TCP/TLS transport type, you can enable CRLF Keep-
Alive feature, using the UsePingPongKeepAlive
parameter.
Defines the interval (in seconds) between keep-alive
messages sent by the device when the Proxy Keep-Alive
feature is enabled (see the 'Proxy Keep-Alive' parameter in
this table).
The valid range is 5 to 2,000,000. The default is 60.
Note: The parameter is applicable only if the 'Proxy Keep-
Alive' parameter is set to Using Options.
Determines whether the device switches from a redundant
proxy to the primary proxy when the primary proxy
becomes available again.

[-1] Not configured = (Default) Proxy redundancy
method is according to the settings of the global
parameter, ProxyRedundancyMode.

[0] Parking = The device continues operating with the
redundant (now active) proxy even if the primary proxy
returns to service. If the redundant proxy subsequently
becomes unavailable, the device operates with the next
configured redundant proxy.

[1] Homing = The device always attempts to operate
with the primary proxy. The device switches back to the
primary proxy whenever it becomes available.
Notes:

To enable this functionality, you must also enable the
Proxy Keep-Alive feature (see the 'Proxy Keep-Alive'
parameter in this table).

The Homing option can only be used if the 'Proxy Keep-
Alive' parameter is set to Using Options.
Enables load balancing between proxy servers of the Proxy
Set.

[0] Disable = (Default) Disables proxy load balancing.

[1] Round Robin = A list of all possible proxy IP
addresses is compiled. This list includes all IP
addresses of the Proxy Set after DNS resolutions
(including NAPTR and SRV, if configured). After this list
is compiled, the Proxy Keep-Alive feature (enabled by
the 'Proxy Keep-Alive' and 'Proxy Keep-Alive Time'
parameters in this table) tags each entry as "offline" or
"online". Load balancing is only performed on proxy
servers that are tagged as "online". All outgoing
messages are equally distributed across the list of IP
addresses. REGISTER messages are also distributed
unless a RegistrarIP is configured. The IP address list is
refreshed every user-defined interval (see the
ProxyIPListRefreshTime parameter). If a change in the
order of the IP address entries in the list occurs, all load
statistics are erased and balancing starts over again.
