Cisco SG300-10 spf module not recognized

[MayteGarcia]

Hi all, I have 2 Cisco SG300-10 switches with MFEFX1 spf modules. Although these modules should be supported, it seems they are not working properly.

If I execute SH fiber-ports optical-transceiver I get

SwInter1#show fiber-ports optical-transceiver interface gi10

   Port      Temp  Voltage Current Output Input LOS
                                   Power  Power
----------- ------ ------- ------- ------ ----- ---
   gi10      N/S     N/S     N/S    N/S    N/S  N/S

 Temp         - Internally measured transceiver temperature
 Voltage      - Internally measured supply voltage
 Current      - Measured TX bias current
 Output Power - Measured TX output power in milliWatts
 Input Power  - Measured RX received power in milliWatts
 LOS          - Loss of signal
 N/A - Not Available, N/S - Not Supported, W - Warning, E - Error

Could you help me with this?

Thanks in advance

Hi

yes those sfps are supported , whats the led on the port show  when there connected ?

Have you a spare cable incase the fibre is bad ?  What does it show you under the view log and ip configuration section in the GUI when the sfps are connected ? Whats the current port configuration on each side

Hi Mark,

The led is green, also the status is connected

When I insert the spf module, this appears in the log

6-Mar-2014 19:04:22 %Fiber-I-SFP-PRESENT-CHNG: gi10 SFP status is present.
06-Mar-2014 19:04:23 %HAL_config_phy-I-CHNGCOMBOMEDIA: Media changed from copper

06-Mar-2014 19:04:29 %STP-W-PORTSTATUS: gi10: STP status Forwarding

The ports are simply configured with speed 100. It's being used only  vlan 1.

Thanks

Is there any logs further after spanning-tree goes into forwarding state when you connect the sfp , it show the interface come up , vlan come up ,  go into forwarding mode is there anything further ?

Is there any other physical connections connecting these 2 switches , just to rule out stp disabling the port due to l2 loop

Are you running the latest f/w 1.3.5.8

Do you get the same result if you connect by copper

[MayteGarcia]

There are no more logs after that and there are no other physical connections between these switches.

I'll try to upgrade the firmware, thanks.

I haven't tried yet with fiber converters. I hoped to avoid them. But I'll try.

[Mark Malone]

Yes i would go with the fw upgrade first , the fact that your fiber output shows not supported but your led is green and connected doesn't seem right , even though Cisco say they support these sfps there seems to be a lot of different forums out there saying they have hardware/compatibility issues and not only on the sg300s but also on the srw models as well

good luck

[Mark Malone]

This list also confirms your sfp is supported for sg300-10 as well so it has to be some compatibility issue , i have attached latest fw for you from last August
