switch connected on 802.1x port

Hi All, can any body tell me what happens when a switch/hub is connected to a 802.1x port which is configured for guest vlan if switch does not receive 802.1x request on that port from switch/hub..all the pcs connected to that port will be part of guest vlan or there will not be any connectivity between 802.1x switch & NON 802.1X SWITCH/HUB..

If IEEE 802.1x authentication times out while waiting for an EAPOL message exchange and MAC authentication bypass is enabled, the switch can use the client MAC address for authorization. If the client MAC address is valid and the authorization succeeds, the switch grants the client access to the network. If the client MAC address is invalid and the authorization fails, the switch assigns the client to a guest VLAN that provides limited services if a guest VLAN is configured.
