New in version 2.8.
| Parameter | Choices/Defaults | Comments | |
|---|---|---|---|
| client_timeout string | Specifies a timeout for Late Binding. This is the time limit for the client to provide the application data required to select a back-end server. That is, this is the maximum time that the BIG-IP system waits for information about the sender and the target. This information typically arrives at the beginning of the FIX logon packet. When 0, or immediate, allows for no time beyond the moment of the first packet transmission.When indefinite, disables the limit. This allows the client unlimited time to send the sender and target information. | ||
| description string | Description of the profile. | ||
| explicit_flow_migration boolean |
| Specifies whether a qualified late-binding connection requires an explicit iRule command to migrate down to ePVA hardware. When no, a late-binding connection migrates down to ePVA immediately after establishing the server-side connection.When yes, this parameter stops automatic migration to ePVA, and requires that the iRule explicitly trigger ePVA processing by invoking the release_flow iRule command. This allows an iRule author to control when the connection uses the ePVA hardware. | |
| idle_timeout string | Specifies the length of time that a connection is idle (has no traffic) before the connection is eligible for deletion. When creating a new profile, if this parameter is not specified, the remote device will choose a default value appropriate for the profile, based on its parent profile.When a number is specified, indicates the number of seconds that the TCP connection can remain idle before the system deletes it. When indefinite, specifies that the system does not delete TCP connections regardless of how long they remain idle.When 0, or immediate, specifies that the system deletes connections immediately when they become idle. | ||
| ip_df_mode string |
| Specifies the Don't Fragment (DF) bit setting in the IP Header of the outgoing TCP packet. When pmtu, sets the outgoing IP Header DF bit based on IP pmtu setting.When preserve, sets the outgoing Packet's IP Header DF bit to be same as incoming IP Header DF bit.When set, sets the outgoing packet's IP Header DF bit.When clear, clears the outgoing packet's IP Header DF bit. | |
| ip_tos_to_client string | Specifies, for IP traffic passing through the system to clients, whether the system modifies the IP type-of-service (ToS) setting in an IP packet header. May be a number between 0 and 255 (inclusive). When a number, specifies the IP ToS setting that the system inserts in the IP packet header. When pass-through, specifies that the IP ToS setting remains unchanged.When mimic, specifies that the system sets the ToS level of outgoing packets to the same ToS level of the most-recently received incoming packet. | ||
| ip_tos_to_server string | Specifies, for IP traffic passing through the system to back-end servers, whether the system modifies the IP type-of-service (ToS) setting in an IP packet header. May be a number between 0 and 255 (inclusive). When a number, specifies the IP ToS setting that the system inserts in the IP packet header. When pass-through, specifies that the IP ToS setting remains unchanged.When mimic, specifies that the system sets the ToS level of outgoing packets to the same ToS level of the most-recently received incoming packet. | ||
| ip_ttl_mode string |
| Specifies the outgoing TCP packet's IP Header TTL mode. When proxy, sets the outgoing IP Header TTL value to 255/64 for IPv4/IPv6 respectively.When preserve, sets the outgoing IP Header TTL value to be same as the incoming IP Header TTL value.When decrement, sets the outgoing IP Header TTL value to be one less than the incoming TTL value.When set, sets the outgoing IP Header TTL value to a specific value(as specified by ip_ttl_v4 or ip_ttl_v6. | |
| ip_ttl_v4 integer | Specifies the outgoing packet's IP Header TTL value for IPv4 traffic. Maximum TTL value that can be specified is 255. | ||
| ip_ttl_v6 integer | Specifies the outgoing packet's IP Header TTL value for IPv6 traffic. Maximum TTL value that can be specified is 255. | ||
| keep_alive_interval integer | Specifies the keep-alive probe interval, in seconds. | ||
| late_binding boolean |
| Enables intelligent selection of a back-end server or pool, using an iRule to make the selection. | |
| link_qos_to_client string | Specifies, for IP traffic passing through the system to clients, whether the system modifies the link quality-of-service (QoS) setting in an IP packet header. The link QoS value prioritizes the IP packet relative to other Layer 2 traffic. You can specify a number between 0 (lowest priority) and 7 (highest priority). When a number, specifies the link QoS setting that the system inserts in the IP packet header. When pass-through, specifies that the link QoS setting remains unchanged. | ||
| link_qos_to_server string | Specifies, for IP traffic passing through the system to back-end servers, whether the system modifies the link quality-of-service (QoS) setting in an IP packet header. The link QoS value prioritizes the IP packet relative to other Layer 2 traffic. You can specify a number between 0 (lowest priority) and 7 (highest priority). When a number, specifies the link QoS setting that the system inserts in the IP packet header. When pass-through, specifies that the link QoS setting remains unchanged. | ||

| server string / required | The BIG-IP host. You may omit this option by setting the environment variable F5_SERVER. | ||
| server_port integer | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable F5_SERVER_PORT. | |
| ssh_keyfile path | Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable ANSIBLE_NET_SSH_KEYFILE. | ||
| timeout integer | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error. | ||

| rtt_from_client boolean |
| When yes, specifies that the system uses TCP timestamp options to measure the round-trip time to the client. | |
| rtt_from_server boolean |
| When yes, specifies that the system uses TCP timestamp options to measure the round-trip time to the server. | |
| server_sack boolean |
| Specifies whether the BIG-IP system processes Selective ACK (Sack) packets in cookie responses from the server. | |

| tcp_close_timeout string | Specifies the length of time a connection can remain idle before deletion. | ||
| tcp_generate_isn boolean |
| When yes, specifies that the system generates initial sequence numbers for SYN packets, according to RFC 1948. | |
| tcp_handshake_timeout string | Specifies the acceptable duration for a TCP handshake, that is, the maximum idle time between a client synchronization (SYN) and a client acknowledgment (ACK). If the TCP handshake takes longer than the timeout, the system automatically closes the connection. When a number, specifies how long the system can try to establish a TCP handshake before timing out. When disabled, specifies that the system does not apply a timeout to a TCP handshake.When indefinite, specifies that attempting a TCP handshake never times out. | ||

| timeout_recovery string |
| Specifies how to handle client-timeout errors for Late Binding. Timeout errors may be caused by a DoS attack or a lossy connection. When disconnect, causes the BIG-IP system to drop the connection.When fallback, reverts the connection to normal FastL4 load-balancing, based on the client's TCP header. This causes the BIG-IP system to choose a back-end server based only on the source address and port. | |
