楼主参考一下下面表格
Table 11. Meaning of Switch LED Colors in Different Modes






Port Mode
Port LED Color
Meaning
STAT (port status)
Off
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.








Color
Network Module Link Status
Off
Link is off.
Green
Link is on; no activity.
Blinking green
Activity on a link; no faults.


Note
The LED will blink green even when there is very little control traffic.
Blinking amber
Link is off due to a fault or because it has exceeded a limit set in the switch software.


Caution
Link faults occur when noncompliant cabling is connected to an SFP/SFP+/SFP28 port. Use only standard-compliant cabling to connect to Cisco SFP/SFP+/SFP28 ports. You must remove from the network any cable or device that causes a link fault.
Amber
Link for the SFP/SFP+/SFP28 has been disabled.
