'Peer timed out' : No response from the peer switch. 'Peer autojoin in progress' : Peer switch is autojoin in progress. 'Peer is not autojoin eligible' : Peer switch not autojoin eligible. 'Peer with incompatible software version' : Peer switch running incompatible software version. 'Peer autojoin validations failed' : Attempt to autojoin by the peer failed. 'Peer with multiple VSF interfaces attempting to autojoin' : Attempt to autojoin via multiple VSF interfaces. 'Peer attempting to autojoin on non-provisioned interface' : Peer switch VSF interface configuration mismatch. 'Peer with non-default VSF interface attempting to autojoin' : Attempt to autojoin on non default VSF interface. 'Peer autojoin failed as there is no free member number available': Attempt to autojoin by the peer failed as there is no free member number available. 'Peer autojoin failed as it is connected in incorrect direction' : Attempt to autojoin by the peer failed as it is not connected in right direction. 'Peer with inconsistent VSF link configuration' : Peer switch with VSF link configuration mismatch.
