Blinking orange light on ports

Hello everyone,

I found several ports blinking orange all the time. The other ports are blinking green normally.

GigabitEthernet2/0/11 is up, line protocol is up (connected)
Hardware is Gigabit Ethernet, address is 2c86.d219.638b (bia 2c86.d219.638b)

sw-241#sho interfaces statu | in 2/0/11

Port            Name          Status        Vlan   Duplex Speed    Type
Gi2/0/11 link to office  connected   trunk     full      1000    1000BaseLX SFP

There is no errors, half-duplex  , drops , I can't find any abnormal place.

Why the port blinking orange? Any suggestions?

Thank you for any answers

Post the complete output to the command "sh controll e Gi 2/0/11".

I don't see anything here.
This is an SFP port, right? Does the patch cable go from Duplex to Simplex?

[marce1000]

 - Disconnect the(a) port and re-connect it, after it starts blinking orage issue show logging on the switch. Are there any error messages ?

[tianwen.zhao]

Thank you for your reply

There is no error messages in show logging

Thanks

[marce1000]

- Ok, further more 1) Connect a console and followup on console output, watch for error message  2) Better : configure a syslog server, check the syslog server periodically for error messages coming from the switch 3)                       Check the spanning-tree status per-vlan (!)
