1) means your router is sending a SABME message to the network.
http://www.cisco.com/en/US/tech/tk713/tk628/technologies_tech_note09186a00801509d7.shtml

2.If Layer 2 is stable, the router and switch must begin to synchronize with each other. The Set Asynchronous Balanced Mode Extended (SABME) message appears on the display. This message indicates that Layer 2 tries to initialize with the other side. Either side can send the message and try to initialize with the other side. If the router receives the SABME message, it must send back an Unnumbered Acknowledge frame (UAf). The router then changes the Layer 2 status to MULTIPLE_FRAME_ESTABLISHED


2) Not sure what the second one is, but seems people who get that message have their config wrong. Most likely clocking issue.
