M4300-24X24F Simplex SFP not working
Hey Guys, I´ve got an M4300-24x24F (Version: 12.0.9.3) switch with several SFP and Copper working fine. Now i want to use a simplex SFP, but get an error: "1/0/14 Port programming failed with e...
I got new FS Simplex SFPs. I tried them in the Switch but they didn´t worked at first.
I checked the port configuration again to recognize that the port-speed is configured for 10G, when I change it to 1000 the link comes up.
When I change the SFP it falls back too 10G. I think the switch identify it as an 10G SFP and change the port automatically to 10G even if it is set to 1000 by hand.
Hi Chris
Sorry about this, it looks like an interoperability issue with this third-party transceiver. Can you confirm it's a <<GLC-BX-U-C PROLABS GE/FC, SFP-BiDi, 1000BASE-BX, Single LC Connector, Tx1310nm/Rx1490nm, 10-20KM, with DOM function>>? Also can you confirm this very transceiver (and its SMF simplex fiber link) is up when plugged in another switch? I just want to isolate the issue first.
Next we'll need the output of these four commands in the console if the transceiver is inserted in port 1/0/14, if not please specify the right port as described starting page 202 of the CLI admin manual:
M4300-24X24F #show fiber-ports optics 1/0/14
M4300-24X24F #show fiber-ports optics-info 1/0/14
M4300-24X24F #show fiber-ports optics-eeprom 1/0/14
M4300-24X24F #show fiber-ports optics-diag 1/0/14
With this info we'll see, I hope, where the problem is and if we can fix it or not.
