Port LED
Meaning
No link, or port was administratively shut down.
Link present but not sending or receiving data.
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.
Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data.
After a port is reconfigured, the port LED can remain amber for up to 30 seconds
as STP checks the switch for possible loops.
