> # VSAN Timers

> Field | Description
> --- | ---
> VSAN Id | The ID of the VSAN.
> R_A_TOV | The Resource_Allocation_Timeout Value used for FxPorts as the timeout value for determining when to reuse an NxPort resource such as a Recovery_Qualifier. It represents E_D_TOV plus twice the maximum time that a frame may be delayed within the fabric and still be delivered. Note that all switches in a fabric should be configured with the same value of this timeout.
> D_S_TOV | The Distributed_Services_Timeout Value which indicates that how long a distributed services requestor will wait for a response.
> E_D_TOV | The Error_Detect_Timeout Value used for FxPorts as the timeout value for detecting an error condition. Note that all switches in a fabric should be configured with the same value of this timeout. Note that value must be less than value of D_S_TOV.
> NetworkDropLatency | Network latency of this switch on this VSAN.
