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.
Note After a port is reconfigured, the port LED can remain amber
for up to 30 seconds as STP checks the switch for possible
loops.
Flashing amber Port is blocked by STP and is transmitting or receiving packets.
