'Load Balancing
Mode'
load-balancing-
mode
[UpstreamGroup_
LoadBalancingMode]
Defines the load-balancing of traffic method for the hosts belonging to
the Upstream Group.
■ [0] Round Robin = (Default) Traffic requests are balanced across
all hosts. Every consecutive request is sent to the next available
host.
■ [1] IP Hash = All requests from a given client (by IP address) is
sent to the same host, regardless of current load.
■ [2] Least Connections = New requests are sent to the host with
the fewest active connections.
Note: The NGINX directive for this parameter is "ip-hash (1)", "least-
conn (2)", and "round-robin (0)".
Configuring Upstream Hosts
The Upstream Hosts table lets you configure up to 50 Upstream Hosts. The Upstream Hosts table
is a "child" of the Upstream Group table (see Configuring Upstream Groups on page282) and
therefore, Upstream Hosts are configured per Upstream Group. Up to 5 Upstream Hosts can be
configured per Upstream Group.
The following procedure describes how to configure Upstream Hosts through the Web interface.
You can also configure it through ini file [UpstreamHost] or CLI (configure network > http-
proxy > upstream-host).
➢ To configure an Upstream Host:
1. Open the Upstream Groups table (Setup menu > IP Network tab > HTTP Proxy folder >
Upstream Groups).
2. In the table, select the required Upstream Group index row, and then click the Upstream
Hosts link located below the table; the Upstream Hosts table appears.
3. Click New; the following dialog box appears:
