BIG-IP virtual server types in f5 –>
| Virtual server type | Description of virtual server type |
| Standard | A Standard virtual server directs client traffic to a load balancing pool and is the most basic type of virtual server. It is a general purpose virtual server that does everything not expressly provided by the other types of virtual servers. For information about the configuration properties of a Standard virtual server, refer to K93017176: Overview of the Standard virtual server. |
| Forwarding (Layer 2) | A Forwarding (Layer 2) virtual server typically shares the same IP address as a node in an associated Virtual Local Area Network (VLAN). A Forwarding (Layer 2) virtual server is used in conjunction with a VLAN group. For information about Forwarding (Layer 2) virtual servers, refer to K10371011: Overview of the Forwarding (Layer 2) virtual server. |
| Forwarding (IP) | A Forwarding (IP) virtual server forwards packets directly to the destination IP address specified in the client request. A Forwarding (IP) virtual server has no pool members to load balance. For information about Forwarding (IP) virtual servers, refer to K7595: Overview of IP forwarding virtual servers. |
| Performance (Layer 4) | A Performance (Layer 4) virtual server has a FastL4 profile associated with it. A Performance (Layer 4) virtual server increases the speed at which the virtual server processes packets. For information about Performance (Layer 4) virtual servers, refer to K01155812: Overview of the Performance (Layer 4) virtual server. |
| Performance (HTTP) | A Performance (HTTP) virtual server has a Fast HTTP profile associated with it. The Performance (HTTP) virtual server and related profile increase the speed at which the virtual server processes HTTP requests. For information about Performance (HTTP) virtual servers, refer to K27310443: Overview of the Performance (HTTP) virtual server. |
| Stateless | A Stateless virtual server improves the performance of User Datagram Protocol (UDP) traffic in specific scenarios. For information about Stateless virtual servers, refer to K13675: Overview of the stateless virtual server. |
| Reject | A Reject virtual server rejects any traffic destined for the virtual server IP address. |
| DHCP | A DHCP virtual server relays Dynamic Host Configuration Protocol (DHCP) client requests for an IP address to one or more DHCP servers, and provides DHCP server responses with an available IP address for the client. |
| Internal | An Internal virtual server enables usage of Internet Content Adaptation Protocol (ICAP) servers to modify HTTP requests and responses by creating and applying an ICAP profile and adding Request Adapt or Response Adapt profiles to the virtual server. For information about the Internal virtual server, refer to K15819: Overview of the internal virtual server. |
| Message Routing | A Message Routing virtual server routes messages between connections for various application protocols and functions in accordance with the respective protocol session profile and router profile. The supported protocols include:Session Initiation Protocol (SIP)DiameterMessage Queuing Telemetry Transport (MQTT) (supported in BIG-IP 14.0.0 and later)For more information, refer to the BIG-IP Service Provider: Message Routing and BIG-IP Service Provider: Diameter Administration manuals. |
