CLI Reference

config load-balance profile

config load-balance profile

Use this command to configure virtual server profiles. A profile is a configuration object that defines how you want the FortiADC virtual server to handle traffic for specific protocols. Virtual server profiles determine settings used in network communication on the client-FortiADC segment, in contrast to real server profiles, which determine the settings used in network communication on the FortiADC-real server segment.

Table 10 describes usage for profile type, including compatible virtual server types, load balancing methods, and persistence methods.

Profile usage

Profile Usage VS Type LB Methods Persistence

FTP

Use with FTP servers.

Note: The setting client-address (in GUI, "Source Address") only works for layer 7 and layer 2. Under layer 7 and layer 2, only client-address and timeout_tcp_session are effective.

Layer 7, 4, 2

Round Robin, Least Connections, Fastest Response

Source Address, Source Address Hash

HTTP

Use for standard, unsecured web server traffic.

Layer 7, Layer 2

Layer 7: Round Robin, Least Connections, URI Hash, Full URI Hash, Host Hash, Host Domain Hash

Layer 2: Same as Layer 7, plus Destination IP Hash

Source Address, Source Address Hash, Source Address-Port Hash, HTTP Header Hash, HTTP Request Hash, Cookie Hash, Persistent Cookie, Insert Cookie, Embedded Cookie, Rewrite Cookie

HTTPS

Use for secured web server traffic when offloading TLS/SSL from the backend servers. You must import the backend server certificates into FortiADC and select them in the HTTPS profile.

Layer 7, Layer 2

Same as HTTP

Same as HTTP, plus SSL Session ID

HTTP Turbo

Use for unsecured HTTP traffic that does not require advanced features like caching, compression, content rewriting, rate limiting, Geo IP blocking, or source NAT. The profile can be used with content routes and destination NAT, but the HTTP request must be in the first data packet.

This profile enables packet-based forwarding that reduces network latency and system CPU usage. However, packet-based forwarding for HTTP is advisable only when you do not anticipate dropped packets or out-of-order packets.

Layer 7

Round Robin, Least Connections, Fastest Response

Source Address

RADIUS

Use with RADIUS servers.

Layer 7

Round Robin

RADIUS attribute

RDP Use with Windows Terminal Server (remote desktop protocol). Layer 7 Round Robin, Least Connections Source Address, Source Address Hash, Source Address-Port Hash, RDP Cookie
SIP Use with applications that use session initiation protocol (SIP), such as VoIP, instant messaging, and video. Layer 7 Round Robin, URI Hash, Full URI Hash Source Address, Source Address Hash, Source Address-Port Hash, SIP Call ID

TCP

Use for other TCP protocols.

Layer 4, Layer 2

Layer 4: Round Robin, Least Connections, Fastest Response

Layer 2: Round Robin, Least Connections, Fastest Response, Destination IP Hash

Source Address, Source Address Hash

TCPS

Use for secured TCP when offloading TLS/SSL from the backend servers. Like the HTTPS profile, you must import the backend server certificates into FortiADC and select them in the TCPS profile.

Layer 7, Layer 2

Layer 7: Round Robin, Least Connections

Layer 2: Round Robin, Least Connections, Destination IP Hash

Source Address, Source Address Hash, Source Address-Port Hash, SSL Session ID

UDP

Use for other UDP protocols.

Layer 4, Layer 2

Layer 4: Round Robin, Least Connections, Fastest Response

Layer 2: Round Robin, Least Connections, Fastest Response, Destination IP Hash

Source Address, Source Address Hash

DNS

Used with DNS servers

Layer 7

Round Robbin, Least Connections Not supported.

IP

Combines with Layer 2 TCP/UDP/HTTP virtual server to balance the rest of the IP packets passed through FortiADC. When running the IP protocol 0 virtual servers, the traffic always tries to match none protocol 0 virtual servers first.

Layer 2

Round Robbin only Source Address, Source Address Hash

DIAMETER

Used with Diameter server.

Layer 7

Round Robbin only Source Address
MySQL Used with MySQL service to load- balance MySQL requests among the MySQL servers. It has two working modes: one is "single-primary" and the other is "sharding-data". Creating an MySQL profile also adds the MySQL-type health-check. Layer 7 Round Robbin, Least Connections Not supported
RTMP Used to configure RTSP profiles. Layer 7 Round Robbin, Least Connections Source Address, Source Address Hash
RTSP Used to configure RTMP profiles. Layer 7 Round Robbin, Least Connections Source Address, Source Address Hash
SMTP Used with SMTP servers. Layer 7 Round Robbin, Least Connections Source Address, Source Address Hash

EXPLICIT_HTTP

A simple explicit/forward HTTP proxy mode.

In this mode, you don’t need to add backend real server pool. The destination IP address of the downstream is specified by the URL or Host field of the client request.

Layer 7

Specify a Geo IP allowlist configuration object.

client-address Use the original IP address as the source address in the connection to the real server.

HTTP

buffer-pool

Enable to use buffering.

tune-bufsize

Specify the buffer size for a session when buffer-pool is enabled. Specify lower values to allow more sessions to coexist in the same amount of RAM, and higher values for traffic with larger HTTP body content. The default is 8,030 bytes. The valid range is 128 to 2,147,483,647.

caching

Specify the name of the caching configuration object.

client-address

Use the original client IP address as the source address in the connection to the real server.

client-timeout

Client-side TCP connection timeout. The default is 50 seconds. The valid range is from 1 to 3,600.

http-keepalive-timeout

The default is 50 seconds. The valid range is 1 to 3,600.

http-mode

  • KeepAlive. Do not close the connection to the real server after each HTTP transaction. Instead, keep the connection between FortiADC and the real server open until the client-side connection is closed. This option is required for applications like Microsoft SharePoint.
  • OnceOnly. An HTTP transaction can consist of multiple HTTP requests (separate requests for an HTML page and the images contained therein, for example). To improve performance, the "once only" flag instructs the FortiADC to evaluate only the first set of headers in a connection. Subsequent requests belonging to the connection are not load balanced, but sent to the same server as the first request.
  • ServerClose. Close the connection to the real server after each HTTP transaction.

http-request-timeout

Client-side HTTP request timeout. The default is 50 seconds. The valid range is 1 to 3,600.

http-x-forwarded-for

Enable this option to append the client IP address found in IP layer packets to the HTTP header, for example, X-forwarded-for: 192.168.161.100.

http-x-forwarded-for-header

Specify a custom name for the HTTP header which carries the client IP address. Do not include the 'X-' prefix. Examples: Forwarded-For, Real-IP, or True-IP.

queue-timeout

Specifies how long connection requests to a backend server remain in a queue if the server has reached its maximum number of connections. If the timeout period expires before the client can connect, FortiADC drops the connection and sends a 503 error to the client. The default is 5 seconds. The valid range is 1 to 3,600.

server-timeout

Server-side IP session timeout. The default is 50 seconds. The valid range is 1 to 3,600.

Use this command to configure virtual server profiles. A profile is a configuration object that defines how you want the FortiADC virtual server to handle traffic for specific protocols. Virtual server profiles determine settings used in network communication on the client-FortiADC segment, in contrast to real server profiles, which determine the settings used in network communication on the FortiADC-real server segment.

Table 10 describes usage for profile type, including compatible virtual server types, load balancing methods, and persistence methods.

Profile usage

Profile Usage VS Type LB Methods Persistence

FTP

Use with FTP servers.

Note: The setting client-address (in GUI, "Source Address") only works for layer 7 and layer 2. Under layer 7 and layer 2, only client-address and timeout_tcp_session are effective.

Layer 7, 4, 2

Round Robin, Least Connections, Fastest Response

Source Address, Source Address Hash

HTTP

Use for standard, unsecured web server traffic.

Layer 7, Layer 2

Layer 7: Round Robin, Least Connections, URI Hash, Full URI Hash, Host Hash, Host Domain Hash

Layer 2: Same as Layer 7, plus Destination IP Hash

Source Address, Source Address Hash, Source Address-Port Hash, HTTP Header Hash, HTTP Request Hash, Cookie Hash, Persistent Cookie, Insert Cookie, Embedded Cookie, Rewrite Cookie

HTTPS

Use for secured web server traffic when offloading TLS/SSL from the backend servers. You must import the backend server certificates into FortiADC and select them in the HTTPS profile.

Layer 7, Layer 2

Same as HTTP

Same as HTTP, plus SSL Session ID

HTTP Turbo

Use for unsecured HTTP traffic that does not require advanced features like caching, compression, content rewriting, rate limiting, Geo IP blocking, or source NAT. The profile can be used with content routes and destination NAT, but the HTTP request must be in the first data packet.

This profile enables packet-based forwarding that reduces network latency and system CPU usage. However, packet-based forwarding for HTTP is advisable only when you do not anticipate dropped packets or out-of-order packets.

Layer 7

Round Robin, Least Connections, Fastest Response

Source Address

RADIUS

Use with RADIUS servers.

Layer 7

Round Robin

RADIUS attribute

RDP Use with Windows Terminal Server (remote desktop protocol). Layer 7 Round Robin, Least Connections Source Address, Source Address Hash, Source Address-Port Hash, RDP Cookie
SIP Use with applications that use session initiation protocol (SIP), such as VoIP, instant messaging, and video. Layer 7 Round Robin, URI Hash, Full URI Hash Source Address, Source Address Hash, Source Address-Port Hash, SIP Call ID

TCP

Use for other TCP protocols.

Layer 4, Layer 2

Layer 4: Round Robin, Least Connections, Fastest Response

Layer 2: Round Robin, Least Connections, Fastest Response, Destination IP Hash

Source Address, Source Address Hash

TCPS

Use for secured TCP when offloading TLS/SSL from the backend servers. Like the HTTPS profile, you must import the backend server certificates into FortiADC and select them in the TCPS profile.

Layer 7, Layer 2

Layer 7: Round Robin, Least Connections

Layer 2: Round Robin, Least Connections, Destination IP Hash

Source Address, Source Address Hash, Source Address-Port Hash, SSL Session ID

UDP

Use for other UDP protocols.

Layer 4, Layer 2

Layer 4: Round Robin, Least Connections, Fastest Response

Layer 2: Round Robin, Least Connections, Fastest Response, Destination IP Hash

Source Address, Source Address Hash

DNS

Used with DNS servers

Layer 7

Round Robbin, Least Connections Not supported.

IP

Combines with Layer 2 TCP/UDP/HTTP virtual server to balance the rest of the IP packets passed through FortiADC. When running the IP protocol 0 virtual servers, the traffic always tries to match none protocol 0 virtual servers first.

Layer 2

Round Robbin only Source Address, Source Address Hash

DIAMETER

Used with Diameter server.

Layer 7

Round Robbin only Source Address
MySQL Used with MySQL service to load- balance MySQL requests among the MySQL servers. It has two working modes: one is "single-primary" and the other is "sharding-data". Creating an MySQL profile also adds the MySQL-type health-check. Layer 7 Round Robbin, Least Connections Not supported
RTMP Used to configure RTSP profiles. Layer 7 Round Robbin, Least Connections Source Address, Source Address Hash
RTSP Used to configure RTMP profiles. Layer 7 Round Robbin, Least Connections Source Address, Source Address Hash
SMTP Used with SMTP servers. Layer 7 Round Robbin, Least Connections Source Address, Source Address Hash

EXPLICIT_HTTP

A simple explicit/forward HTTP proxy mode.

In this mode, you don’t need to add backend real server pool. The destination IP address of the downstream is specified by the URL or Host field of the client request.

Layer 7

N/A

N/A

Table 11 provides a summary of the predefined profiles. You can select predefined profiles in the virtual server configuration, or you can create user-defined profiles, especially to include configuration objects like certificates, caching settings, compression options, and IP reputation.

  • OnceOnly. An HTTP transaction can consist of multiple HTTP requests (separate requests for an HTML page and the images contained therein, for example). To improve performance, the "once only" flag instructs the FortiADC to evaluate only the first set of headers in a connection. Subsequent requests belonging to the connection are not load balanced, but sent to the same server as the first request.
  • ServerClose. Close the connection to the real server after each HTTP transaction.
