The keepalive speed is a global configuration that applies to all Aviatrix gateways. Aviatrix gateways send periodic keepalive messages to the Aviatrix Controller that enables the Controller to determine when a gateway’s state changes to monitor when a gateway is down. The following table shows how frequently gateways send keepalive messages and how often the Controller processes these messages.

By default, the keepalive speed is set to Medium. A gateway is considered to be in the UP state if the Controller receives at least 2 (out of a possible 5) messages from that gateway between two consecutive health checks. For example: When set to Fast, the gateway down detection time is between 7 seconds and 14 seconds. When set to Medium, the gateway down detection time is between 1 minute to 2 minutes.
