No link, or port was administratively shut down.
Green
Link present, no activity.
Blinking green
Activity. Port is sending or receiving data.
Alternating
green-amber
Link fault. Error frames can affect connectivity, and errors such as excessive collisions, CRC
errors, and alignment and jabber errors are monitored for a link-fault indication.
Amber
Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data.
After a port is reconfigured, the port LED can be amber for up to 30 seconds as STP checks the
switch for possible loops.
