> # About Link State Record Defaults

> Each time a new switch enters the fabric, a link state record (LSR) is sent to the neighboring switches, and then flooded throughout the fabric. Table 23-1 displays the default settings for switch responses.

> Table 23-1 LSR Default Settings
> LSR Option | Default | Description
> --- | --- | ---
> Acknowledgment interval (RxmtInterval) | 5 seconds | The time a switch waits for an acknowledgment from the LSR before retransmission.
> Refresh time (LSRefreshTime) | 30 minutes | The time a switch waits before sending an LSR refresh transmission.
> Maximum age (MaxAge) | 60 minutes | The time a switch waits before dropping the LSR from the database.

> The LSR minimum arrival time is the period between receiving LSR updates on this VSAN. Any LSR updates that arrive before the LSR minimum arrival time are discarded.

> The LSR minimum interval time is the frequency at which this switch sends LSR updates on a VSAN.
