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	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.

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.

Diameter
Identity	Sets the value of Diameter AVP 264. This AVP can be a character string and specifies the identity of the originating host for Diameter messages. ADC will modify the origin-host avp on client request with the setting value, then transfer it to RS. ADC will modify the origin-host avp on server response with the setting value, then transfer it to the client. Specify the identity in the following format: vs.realm The host is a string unique to the client. The realm is the Diameter realm, specified by the Realm option (described below). If Identity is set with an empty value (nothing), ADC will not change the value of the origin-host in the client or server when it transfer thems The default is empty value.
Realm	Sets the value of Diameter AVP 296. This AVP can be a character string and specifies the Diameter realm from which Diameter messages, including requests, are originated. ADC will modify the origin-realm avp on client request with the setting value, then transfer it to RS. ADC will modify the origin-realm avp on server response with the setting value, then transfer it to the client. If Realm is set with an empty value(nothing),ADC will not change the value of the origin-realm in the client or server when it transfers them. The default is empty value.
product-name	Sets the value of Diameter AVP 269. This AVP can be a character string and specifies the product; for example, “fortiadc”. ADC will modify the Product-Name avp on client request with the setting value, then transfer it to RS. ADC will modify the Product-Name avp on server response with the setting value, then transfer it to the client. If product-name is set with an empty value(nothing), ADC will not change the value of the origin-realm in the client or server when it transfers them. The default is empty value.
Vendor-id	Sets the value of Diameter AVP 266. This AVP can be a character string and specifies the vendor; for example, “156”. ADC will modify the vendor-id avp on client request with the setting value, then transfer it to RS. ADC will modify the vendor-id avp on server response with the setting value, then transfer it to the client. If vendor-ide is set to 0, ADC will not change the value of vendor-id in the client or server when it transfers them. The default is 0.The valid range is 0-4294967295.
Idle-timeout	Default, for different requests with the same session_id avp, if their interval is less than idle-timeout, ADC will dispatch them to the same RS. The default is 300 seconds. The valid range is 1-86400. When this parameter is set, ADC will act in proxy mode.
server-close-propagation	When transfering diameter traffic with server-close-propagation enabled, if one of the servers resets or sends DPR to ADC, ADC will close connection with the client and other servers at the same time. When transfering diameter traffic with server-close-propagation disabled, if one of the servers resets or sends DPR to ADC, ADC will transfer the requests from the client to the other servers. Disabled by default.
