# Refresh a logical switch

The refresh action reclaims the top-of-rack switches in a logical switch. This can be useful when the switch firmware is updated. If a switch in a logical switch is in an unmanaged state due to a firmware version mismatch, it can be brought into the `Monitored` state by refreshing the logical switch.
