This read-only DateAndTime object reports when the last vPC peer-keepalive message was received, containing a special all-zero-based value if a message has never been received. Administrators use it to confirm the local switch is actually still hearing from its peer on schedule, complementing the last-send-time object for the transmit side. For example, a stale last-receive-time despite the local switch continuing to send keepalives would indicate the problem lies with the peer's transmission or the return network path, not the local device.
