S3148 combo ports

Just to add this is what happens if i move from 47 to 49 - and going back to 47

May 31 20:30:07 %S3148P:1 %IFAGT-5-INSERT_OPTICS: Optics SFP inserted in slot 1 port 47

May 31 20:37:54 %S3148P:1 %IFAGT-5-INSERT_OPTICS: Optics SFP inserted in slot 1 port 49
May 31 20:37:56 %STKUNIT1-M:CP %IFMGR-5-OSTATE_UP: Changed interface state to up: Te 1/49

mid-rack4-sw1(conf)#May 31 20:39:55 %STKUNIT1-M:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Te 1/49
May 31 20:39:59 %S3148P:1 %IFAGT-5-REMOVED_OPTICS: Optics SFP removed in slot 1 port 49
May 31 20:40:02 %S3148P:1 %IFAGT-5-INSERT_OPTICS: Optics SFP inserted in slot 1 port 47

nothing happens on port 47 

ColinPuk,

Would you confirm which fiber transceiver you're using and what is it connecting to? Also, you may want to consider trying the auto/hybrid mode and see if that works. This is certainly odd that it works on port 49 and not 47.

Let me know what you see.

Hi Chris,

I have changed the port back to auto/hybrid - still no luck

The Transceiver is dell supplied  for this project

SFP 3080192 Diagnostic Information

From the look of it, the transceiver seems fine.

Would you confirm a couple other things, such as what you're connecting the switch to, and if it is also a 1G connection?

Also, if you run the command "show ip interface brief" does it show the status and protocol as down?

Hi at the other end is an Aruba 6000 - connected at 1gb using om4 mm - this seems not to be the issue as the link comes up using port 49.

Hi could you try this below

interface GigabitEthernet 1/47

combo-port-type fiber

no ip address

portmode hybrid

switchport

speed 1000

duplex full

no shutdown

Hmm, that makes me think, if possible, can you try with another SFP in ports 1/47 and 1/48? It could be related to SFP modules themselves. 

i have changed to another of the dell 1gb modules - still the same issue 

ColinPuk,

You may want to consider calling in to support, as it will likely require direct access to resolve the issue.
